Another Trip to Malaysia Rain forest- Selancar

We have again organised another 4x4 trips extreme adventure to explore Malaysia rain forest to the toughest trail to SELANCAR, in Pahang. Very popular off road trail among the 4x4 enthusiast in Malaysia, it took almost 4 hour to reach the destination. After take a bit nap and morning meal, we continue the journey to test our 4x4.With 6 Mitsubishi Pajero 2.5 Diesel and a Land Rover and led by ex-man Rain Forest Challenge (RFC), the journey will take us approximately 7 to 8 hours depending on route condition to reach the first camp site.

Along the route we have to overcome many obstacles that challenged our mental, team spirit and 4x4 vehicle. V gullies, mud pool,winching and river crossing become normal scenario before we reach the camp site at approximately 6.30 p.m.

After set our camp site and having our dinner, we planned to go for night fishing as the rivers are famous to have plenty type of white water fishes. However,heavy rain has pouring the first night and make us spent most of our night in the tent talking about our adventure.

Second day, the night rain has flooded the river and now we are worried how to plan our journey back because crossing the rivers is dangerous due to high water level and rapid rivers which may submerge our 4 wheels and it is the only way back.The decision has been made to stay for another night and wait for the rapid river to be at safe level for us to cross. So on the second day, fishing and repairing our wheels has become our main activities.However, the 2nd night again the heavy rain has become our great enemy and we have to re-plan our journey either to stay or packed and start our journey escape.

3rd day, decision has been made,pack and prepare for our back and the plan is to take a different route which according to our guide and leader may be a bit tougher.After cleared the camp site area, we start to roll at about 10.30 a.m with hope no rain. This back journey we experienced more on handling our 4 wheels on long 'mud pool', more winching techniques using the snatch block, crossing a rapid river and most important lesson were the teams spirit on our escape.

LESSON from trips: Rescue techniques, winching, winching angle, 50 feet winching techniques,mud pool, snatch block, crossing rapid river, snatch trap, v gullies, teams radio and for us most important were not just the off road tips but being a good team with a high team spirit to overcome the obstacles a long our trips and these made these trip a memorable trips. Another lesson, a good off road team is where everybody play their own role and not being so selfish.

To all Blackwind members and other we have a tremendous trip and a very good lesson too.

Over and out.

4x4 Convoy Rules

Certain rule or procedure need to be practiced when move in big convoy. This is to ensure that your fellow drivers not left behind or lost. These also make your team look well organized.

These rules are crucial to ensuring the safety of participants and members of the public, and to ensure participants arrive at the destination as a group.

Prior to departure

Make sure your vehicle has enough fuel, oil, water well before the run, and is mechanically able to complete the journey. If your four wheel uses excessive fuel, let the Trip Leader know so a fuel stop can be planned.

Convoy Structure: Trip Leader/Convoy Leader

Should be in in front and also as a trip guide. Convoy leader play an essential role to ensure the condition of the convoy.

1. The Trip Leader must obey speed limits at all times, remembering that the rear of the convoy may be a long way back.
2. Constantly view mirrors to ensure the convoy is not spacing out too far.
3. If a lot of traffic lights are encountered, it may be necessary to pull over somewhere safely to reform.
4. A generous use of indicators when changing direction.
5. Inform the group prior to departure of the destination and any stops (perhaps a map).
6. If the convoy is too large to keep together form a couple of groups.

Members' Four Wheel

1. Do not pass other convoy vehicles except in emergency.
2. Watch the leader for passing (use indicators)
3. Maintain a safe distance from the car in front (1 car length for every 16kph/10mph)
4. Do not let the car in front get out of sight.
5. Flash your lights if in trouble.
6. Non-Corvettes at the rear of the convoy, but in front of Tail-end Charlie/Sweeper.

Tail-end Charlie/Sweeper

1. Keep visual contact with the Trip Leader (if possible).
2. Use radios or mobiles to contact Trip Leader when necessary.
3. Contact Trip Leader if there a vehicles at the rear have to travel too fast to keep up.

Type of Convoy

Loose Convoy or Open Convoy

Usually applicable for off roader who has mastered the route or equipped with map or compass and has been detailed brief about the destination.

Close Convoy

All 4x4 members moving within the safe distance and speed depends on the route and trips condition.

On Road Convoy

When in a convoy, we are on display to the public and it is expected that all participants are courteous to all traffic and pedestrians. Burnouts and similar displays are prohibited except during specified events. Speed limits and all traffic rules must be obeyed.

It would be expected that general traffic would at times join or hold up a convoy. It is not essential that all convoy members be strictly together if general traffic has broken the convoy. Provided that members can clearly see and are not excessively behind the next corvette in front, members should continue in that lane and not overtake and risk cutting in front of the car you are overtaking.

Stay aware of the vehicle both in front and behind you. If you find that the vehicles behind you have been split, then slow down or wait safely at any turnoff for those that are following.

When stopping, move off the road as quickly as possible. Do not stop on the roadway.

When approaching RED lights take up as many lanes legally as possible, once past the lights reform into single file again. If you want to go slower than the speed limit or look around let your trip leader know so that you are not holding up the convoy.

Off Road Convoy

1. It is very important during the off road trips to follow these rules to ensure your trips going according as planned and smoothly.
2. Once you're on off road route, your vehicle should be arranged according to the capability of each 4x4 and their recovery equipments.This method is vital for recovery purpose.
3. Ensure you see the vehicle behind you.Don't follow too close and maintained safe distance.
4. The vehicle should take turn one by one when ascending or descending hill or narrow corner.
5. The Trip Leader should guide or inform all team members from time to time on the route condition as a precautionary action.
6. Do not stop or park your four wheel on the middle of the hill, narrow corner,steep hill or route.
7. Do not leave your team member alone in the middle of off road trips.

In case of difficulties or problems:

If a vehicle breaks down or you experience any problems requiring you to pull over and stop, stay with your vehicle and contact the Trip Leader or another member by radio.

Please drive safely and happy off roading! Read more from this post

4x4 Trips with Family

It has been quiet some time I have not taking my family for a trips. We decided to take just a short journey to explore in Malaysian rain forest. So we planned to spend a weekend at place we called 'DUSUN' which we (BLACKWIND) group bought for our special vacation.

Being away from busiest day doing work and spending time in tranquility and peaceful place relieved the stress on our day. Besides inculcating importance of nature preservation to our children, they are also enjoying the beautiful nature in wild stream, cold and peaceful environment hearing the birds chipping.

Snatch Strap

Snatch Strap is a vital equipment for many 4x4 enthusiast when going off road. Don't leave home without it.

A snatch strap is a piece of equipment used to help in the recovery of vehicles bogged in sand or mud. Snatch straps are manufactured from webbing that is capable of approximately 20% stretch under load. This stretching property allows the strap to store kinetic energy, which is used to pull vehicles from a bog. Snatch straps are typically between 6m (20') and 15m (50') in length, with 9m (30') being a common size. Snatch straps also have ratings of permissible working load - e.g. 8000kg.

A snatch strap is used by attaching one end to a rated recovery point on the bogged vehicle (e.g. a recovery hook or loop on the chassis). A second vehicle is required to do the recovery. The snatch strap is laid out on the ground in the direction the bogged vehicle is to be recovered (either forwards or backwards), with an "S" bend in the middle approximately 1m in length. The recovery vehicle is backed up so that the snatch strap can be attached to a second rated recovery point on the rear of the recovery vehicle. The recovery vehicle then drives off, and the strap begins to stretch, building up kinetic energy, until the force keeping the vehicle bogged is overcome, at which point the bogged vehicle is pulled forward (or "snatched", hence the name).

It is essential that proper rated recovery points be used, as snatch straps store dangerous amounts of kinetic energy when under load, and numerous fatalities have resulted from improper use, such as attaching to towbars or towballs not designed to be used as recovery points. Care should also be taken when joining snatch straps, and snatch straps should never be joined using a shackle, as in the event of a failure, the shackle will be flung with great force towards the vehicle who's strap it is still attached to. This has also resulted in several fatalities.

If the snatch strap is to be attached to a loop instead of a hook on the vehicle, a bow shackle should be used.If the strap was to break, the bow shackle will remain attached to the recovery loop, and not be flung as a projectile.

A snatch strap should not be used for towing or winching purposes.

Recovery Equipment-Glove

It is important to use a durable hand glove to protect hand injury during recovery process. Advisable to use recognized and high quality glove such as produced by WARN or ARB.

Advisable to use your glove when handling winch cable or other equipment to avoid severe hand injury.

Principal of 4x4 Vehicle Recovery

When going off road it is normal for 4x4 enthusiast to experience many obstacles to make their trips more challenging and remembered. However, to successfully overcome the obstacles they have to follow the basic principal.

A successful and smooth recovery of your 4x4 should depend on this principal :-

• Mind sanity
• Techniques and knowledge
• Experience
• Precaution Action
• Recovery Equipment
• Safety First

The principal should applies to ensure the recovery process going smooth, fast and safe without severe damage on yourself and your 4x4.

Please don't handle your recovery equipment if you not sure how to use them or read and understand your recovery equipment manual before use it to avoid any injury.

Note: Make sure to store your recovery equipment for fast accession because time is very important to secure your vehicle within a minimum time. Strict "Jungle Code" should applied to preserve and protect the environment during the recovery process.

Normal Recovery Equipment

1. Glove
2. Snatch strap
3. Tree trunk protector
4. Bow or D Shackle
5. Choker Chain
6. Snatch Block
7. Hi-lift jack
8. Ground Anchor

Also prepare yourself mentally and physically before going off road.

Why we like 4x4 ?

Why we like 4x4 adventure?May be because the adventure, the vehicle, result and performance of your 4x4 modification, the mother nature challenge or it can be many thought BUT to experience it is to own it.

My first thought about 4WD is that it just meant for people who works in construction field who always require suitable vehicle to carry their heavy load or equipments. Furthermore, in Malaysia the road tax for this kind of vehicle is tremendously high especially those with diesel engine.

When my friend bought a secondhand 4x4, I asked him why you need this vehicle for? The answer is just to experience the fun of riding 4x4. Good answer but is he financially prepare for the high maintenance, daily fuel consumption, road tax etc. Then, one day I was invited to join the off road adventure event and start to love it.

A month later, I bought a my first 4x4, a Mitsubishi Pajero LO49 1991 Model with diesel engine.

For first time I was amazed how useful this vehicle are, you can carry heavy loads, long endurance and for me with 5 kids, this vehicle is also suitable for family use or trips. You don't have to worry about the road anymore, on road or off road not a problem. I am also lucky because the Malaysia government has reduced the yearly road tax, diesel price and for monthly maintenance 'DO IT YOURSELF'.

With six of us, we have formed a Mitsubishi Pajero club called BLACKWIND

Now we have our own workshop, mechanic, club house and last December 2008, BLACKWIND has joined as a Team Media in the Rainforest Challenge Malaysia 2008 (RFC), the most challenging 4x4 off road adventure event in the world. A very good experience and we have gained a lot of information about off roading, vehicles handling techniques, environment, team spirit etc.

K3,K1 and K7 with Mr Luis/Founder of RFC

Next year, we aimed to join again in the RFC but not as a Media Team but as a challenger in the RFC.

Basic Technique- Offroad Driving

Many of 4x4 owner are really good in understanding their vehicle capability and most of them are well prepared before going off road. However, you are also need to know the basics of your four wheel drive vehicle. To know the basic is will lead you to understand more of your 4x4.

Before proceed with off road activities, first we must know the characteristic of our 4WD including how the 4WD system operating, driving character, your vehicle size, angle and height.Every 4WD have their own advantages and disadvantages. Know your own 4WD and your capability will reduce the risk of your 4WD being in severe damage and most important your safety.

Setting your 4 wheel Gear

First rule is to set your 4 wheel gear. It depend on type of your 4WD either full time 4 wheel or half time 4 wheel gear. For half time 4 wheel normally the hub key located on your front wheel. After locking the hub key, set the gear to either 4 Low (4L) or 4 High (4H) depends on the trek grade.

Setting a suitable gear for different type of obstacles require competence and experience.

Just remember,

Don't change gear in the middle of obstacle, river crossing or descending hill.

If not sure which gear to choose, set at the lowest (1st gear 4L Mode)

Vehicle Angle

Know your vehicle angle is one of the important factor to determine the ability of your 4WD to go through the obstacle when go off-roading.

There 4 type of vehicle angle to know

1. Approach Angle - angle to be consider for climbing

2. Ramp Break Over Angle - angle to measure vehicle height or ground clearance

3. Departure Angle

4. Side Tilt Angle

For safety purpose, do check the route or obstacles before decided to go through it.

Off Road to PEDU

For the first time Blackwind represented by K3 and K6 has joined an off road trip to Pedu, Kedah. Accompanied by 2 RFC ex-man and 4 other 4WD, they have undergone tough trip for first time. The 2006 RFC route at Pedu became their training ground to learn and understand other off road techniques especially handling 4WD in muddy route. For us the best off road knowledge is learn from experience and to equip our vehicles and ourselves before go off roading.

4WD diesel engine or petrol engine?

I have received a comment on which to choose either diesel engine or petrol engine.

There are a few criteria that we need to take into consideration before choosing to buy diesel engine or petrol engine.

Here some tips that I can suggest and hope they are useful.

Engine Price

Usually in Malaysia diesel engine is more expensive compare than petrol engine especially with turbo intercooler system. I am not very sure about the other country pricing.

Engine power

Only diesel engine supported with turbo system able to produce more power and sometimes as good as petrol engine. Petrol engine normally have more power compared with diesel engine roughly about 25%.

Torque

Diesel engine able to generate more torque in low r.p.m and therefor capable to carry more load and have ability to go for long distance journey. Petrol engine have more horsepower and high acceleration but low torque.

Maintenance

Simple maintenance, pay attention on your engine oil (high frequency of changing your engine oil) and if properly maintained it may take longer time for major overhauls. Petrol engine may require more complex maintenance.

Life time Engine

For diesel it may take between 350,000 km to 500,000 km for general overhauls. As for petrol it may take between 200,000 to 350,000 km for general overhauls.

Fuel Consumption

I think when thinking of buying a car or 4WD you may find that diesel engine able to save about 20% to 50% compare with petrol engine

Exhaust Temperature

For diesel engine the exhaust temperature about 600 degree celcius and as for petrol engine about 800 degree celcius. The high temperature of your 4WD the more inflammable.

There are other tips in my opinion that you may find it useful such as how easy to find a mechanic, price, car insurance, availability and price of 4WD spare parts and in Malaysia you may include also roadtax and etc.

But if you buying a 4WD for offroad then you have to take consideration on basic tips such as engine breaking, endurance, torque, maintenance, body lifting, suspension and etc.

What is 4WD System?

The main component that differentiate the 2WD (normal vehicles) and 4WD is on their transmission system or an automotive drive system in which mechanical power is transmitted from the drive shaft to all four wheels.

Normal vehicles only powered by main gear transmission box as compared with 4WD vehicle is also attached additional gear box or transfer case/gear which usually located behind the gear transmission box.

Transfer case main function is as a housing for drive shaft/propeller shaft to move the wheel forward and backward. Transfer case box possess 2 additional set ratio gear that are high (4 High/4H) and low (4 Low/4L).

When you choose a low gear ratio that mean you are doubling the torque to the wheel. Low torque circle with the mechanical transmission system enable all four wheel advantage to climb or to carry heavy load. Please remember that with 4 Low gear ratio does not give you wheel grasp but only to supply more torque for your wheel.

There are two type of 4 wheel system that is full time 4WD and part time 4WD.

In my case,my Mitsubishi Pajero is classified as a part time 4WD and this type of 4WD become more popular in Malaysia.

When to use 4H:

• for traction when the area isn't steep
• when stuck in sand
• extremely slippery conditions
• snow
• ice
• rocky, gravel roads
• gullies
• extremely muddy areas
• ridges

Low Range 4WD

4L is for creeping along at slow speeds. It reduces the strain on your vehicle, just remember to stay below 25mph in low range. While it does not provide more traction, it does provide 2-3 times more torque at about 1/2 or 1/3 of the speeds in high range. Low range gear ratios are approximately half that of high range.

When to use 4L:

• on wet, slippery surfaces
• passing through sandy areas
• on rough trails
• through shallow water
• rock-climbing
• climbing steep hills
• through mud
• descending steep hills

Additional Tips:

Don't change gears in the middle of a water crossing, going up or down hills, or in sand dunes.

Be prepared: Engage low-range 4WD before you need it.

Don't operate 4WD on hard dry surfaces.

When in doubt, use a lower gear!

4WD Diesel Engine

For some 4x4 enthusiast they have a few criteria on which to choose either diesel or petrol engine. Petrol engine capable to generate more acceleration thus more powerful and more fuel consumption as compare with diesel engine. There are advantages and disadvantages of these two engine and as for me, I would prefer a diesel engine.

Diesel Engine

1. Diesel engine was designed for heavy load capacity and long journey as it able to endure high engine compression ratio i.e 20:1
2. Able to produce good engine breaking especially when descending hill's slope
3. Non-complex maintenance, just pay attention on your engine oil and timing
4. Longer life expectancy if properly maintained (350,000 km for overhaul)
5. Diesel is cheaper and able to generate more mileage
6. For long journey expedition, diesel engine is more suitable
7. Diesel engine be able to supply more tork with low r.p.m especially in challenging off road situation
8. Inflammable
9. Non friendly to environment

Petrol Engine

1. Normally able to produce 25% more power compare with diesel
2. Less torque but more acceleration
3. Complex maintenance but easy to find an expert mechanic
4. High consumption on fuel

Simple Wheel drive definition!

4x4, 4wd and four wheel drive and AWD all these terms are define the four-wheel vehicles drive train that allows all four wheels to receive power from the engine simultaneously. Many state people associate the term with off-road vehicles. In additionally these cars are popular in the broader sport utility vehicles category.

Four-wheel drive term suggest huge truck like vehicles that driver that manually drive in switch between street , four-wheel drive mode for low traction conditions such as mud, ice or loose gravel. 4WD systems there are three basic options:

Part-time 4WD

That it must be continually engaged and then disengaged in conditions of light rain or snow. This type of system is best for people, who really don't need 4WD.

Full-time 4WD

This 4x4 more advanced convenient form of 4WD allows you to choose between all of the same settings, but can remain engaged while on dry pavement. Added to the High and Low settings is an automatic or full-time 4WD setting.

All-wheel drive (AWD)

Same as to full-time 4WD in that the system is always sending power to the wheels with the most traction. Little differentiate the AWD has no 2WD switch. It’s operates like 4WD mode. Sometimes the road gets greasy than AWD control the system locks the axles and automatically distributes power to all four of the tires. If the AWD system allows the driver to switch to a "low" range gearing setting, like in the Dodge Durango and Toyota 4Runner, then it is probably planned for severe off-road use.

4wd vehicles found help in the gearing option with equipment of off-road driving. Following are a variety of conditions in which you would want to use 4WD to avoid downhill or spinning:

Hi Range 4WD

If we have necessary than four wheels given facilities to drive full speed. Naturally 4wd mode ratios are very high compare than the gear ratios of 2WD.

Low Range 4WD

Reduces the strain on your vehicle and very slow speed. Every time you just remember to stay below 25mph in low range. Low range gear ratios are approximately half that of high range.

Winching

Winch Challenge

This is the most recent, and usually the most difficult, form of course trialling. Again, a course is laid out with a series of gates and vehicles must complete as many gates in a course as possible. However, these events take place on very difficult terrain- difficult to the extent that vehicles are not expected to be able to complete the course without the use of a recovery winch. Winching is a definite skill in itself, aside from off-road driving, and brings elements of team-playing into the trial, as a successful (and safe) vehicle recovery needs at least 2 people to complete. Some trials are for teams of 2 or 3 vehicles, each helping to recover the others through obstacles. A Winch Challenge may extend to other off-road driving skills, such as building a log bridge to cross a river.

At its most basic, a Winch Challenge vehicle will be a CCV-spec machine with a front-mounted recovery winch. However, a distinct breed of vehicles adapted for Winch Challenges has evolved. The small, open-topped CCV vehicles is not well suited to carrying the often large range of equipment needed for winch recovery in difficult terrain. A larger vehicle with some form of protection from the elements is desired (the short-wheelbase Land Rover Defender, especially in 'Hard Top' guise, is a typical and common basis for a Winch Challenge vehicle). Vehicles often require extensive modification. Under-body protection is needed, given the severity of the terrain involved, and suspension and drive train upgrades are used to get vehicles as far as possible before winching is needed. Roll-cages and 'snorkel' air intakes are required to prevent vehicle damage. The vehicle's electrical system often needs upgrading, with multiple battery banks and high-output alternators being needed to cope with the large currents drawn by a winch. Vehicles increasingly sport winches mounted at the front and rear to greatly increase the options available for recovery.

Modification for Off Road 4WD

There are a few modification to be done on your 4WD before go off-roading (for mild Off-road). While many off-road vehicles can greenland or "two track" most unpaved roads, the desire of many off-roading enthusiasts is to attempt much more challenging terrain. The following listings show the modifications that are done and why:

Vehicle Lifts

A vehicle lift is when the normal height of a vehicle is lifted to increase the amount of clearance between the ground and the bottom of the body or frame of the vehicle. There are numerous types of vehicle lifts:

Body Lift: A simple and cheap way to lift a vehicle that has a body on frame design such as a pickup truck or some SUVs. A body lift consists of larger spacers that replace the normal mounting points of the vehicle's body on its frame. These typically are between 1 - 4 inches. Any more than four inches (102 mm) will create a less sturdy set up. Body lifts are not possible on vehicles with a "Uni-body" construction. Uni-body vehicles have the frame formed into the body, such as on a Jeep Cherokee.

Suspension lift: A suspension lift is when modifications are done to the vehicle's springs, shocks, controlling arms and steering linkage. In this case small or short pieces of the suspension are replaced with longer or larger items of similar construction. Lifting a vehicle changes its driving dynamics and a suspension lift adds to the vehicle's handling capabilities in relation to the increased height.

Remember that all service stations have their storage tanks burried below ground. The colder the ground, the denser the fuel, when it gets warmer petrol expands, so buying in the afternoon or in the evening....your litre is not exactly litre.

In the petroleum business, the specific gravity and the temperature of the petrol, diesel and jet fuel, ethanol and other petroleum products play an important role. A 1 degree rise in temperature is a big deal for this business. But the service stations do not have temperature compensation at the pumps.

When you are filling up, do not squeeze the trigger of the nozzle to a fast mode

If you look, you will see that the trigger has three (3) stages: Low, Middle and High. In slow mode, you should be pumping on low speed, thereby minimizing the vapours that are created, while you are pumping. All hoses at the pump have a vapour return. If you are pumping on the fast rate, some of the liquid that goes to your tank becomes vapour. Those vapours are being sucked up and back into the underground storage tank so you're getting less worth for your money.

One of the most important tips is to fill up when your tank is half full

The reason for this is, the more fuel you have in your tank, the less air occupying its empty space. Petrol evaporates faster than you can imagine. Petroleum storage tanks have an internal floating roof. This roof serves as zero clearance between the petrol and the atmosphere, so it minimizes the evaporation. Unlike service stations, fuel tankers is temperature compensated, so that every litre is actually the exact amount.

Another Reminder, If there is a fuel truck pumping into the storage Tanks, when you stop to buy, do not fill up

Most likely the petrol/diesel is being stirred up as the fuel is being delivered, and you might pick up some of the dirt that normally settles on the bottom.

Hope, with the Tips given will help you get maximum value of your money. Read more from this post

Take the extra mile: Fuel Efficiency Tips

Increases in the price of gas, accompany the increase in the number of fuel-saving scams.

Continuous increase in the price of gas is common news nowadays. This is accompanied by an upsurge in advertising exposures for “gas saving” gadgets. These products attract potential buyers searching for methods to maximize fuel efficiency.

There are important procedures car owners can take in consideration to improve gas mileage.According to the Better Business Bureau, the public should be critical in assessing products that claim gas saving features for vehicle devices or additives for gas and oil.

There are products that feature gas-saving features that really work.In addition to that, consumers could be facing a major engine trouble or a nullified creator’s warranty by putting devices to the engine. Consumers should be wary of these specific advertising slogans: “20 percent fuel efficiency improvement”

A hundred or more devices that feature gas-saving qualities are proven untrue by the Environmental Protection Agency. Worse, there are so-called “gas-saving” devices that may cause a harmful effect to a vehicle’s engine.

Another side effect is more smoke emissions. Examples of these devices are Engine Modifiers, Additives, Fuel Line Gadgets, Liquid Injection, Vapor and Air Release Devices and a lot more.

Consumer testimonials are common in fuel saving ads. Assuming these testimonials are not made up, few consumers test the fuel consumption of their vehicle before putting on the gadget. Therefore, an objective comparison of the fuel consumption before and after the product was added will not be attained.

The following are practical tips to conserve gas:

Efficient driving

Just drive reasonably within the speed limit. Remember that speeds of more than 60 miles per hour increase fuel consumption.

Do not do sudden starts, accelerations and stops.

Acceleration should be done gradually. The gas pedal should not be stepped on more than one fourth of the way down. This will allow the engine to function most efficiently. Gas conservation could reach up to 5 percent if sudden stops, jerks and accelerations are avoided.

Make use of gears for overdrive and cruise control as needed. Fuel efficiency is attained when moving on the highway.

Windows should be closed on highways. Windows that are open can create air drag that can decrease the fuel consumption by 10%.

Take out unnecessary baggage. The trunk should be kept clean, any gadget, tools or loads that are not needed should be taken out. 100 pounds of extra baggage can affect fuel economy by two percent.

The car should always be maintained. The engine should be given a regular tune up, the tires should always have the right air pressure and efficiently aligned, the oil should be changed when needed and air filters replaced regularly. Clogged filters can affect gas consumption adversely by up to ten percent.

Turn off the engine whenever there is an opportunity. Idle engine wastes fuel. There are instances where the engine could be turned off; stopping for gas, waiting for someone, changing tire pressure, caught in traffic and a lot more.

Engine warm-up fuel conservation tips:

Lengthy warming up of the engine should be avoided. 30 to 45 seconds should be enough time.Check if the automatic check is removed after warming up the engine. This is usually stuck which could usually cause poor gas and air combination.

Do not rev the engine. This is usually done before turning off the engine. This causes unnecessary fuel loss and also washes the oil within the cylinder walls. As an effect, there is air pressure loss and consequently fuel loss as well.

Educate yourself as a consumer. Prepare a list of your needs. Prioritize between the necessities and determine the budget and the kind of car that would best fit. Make a selection by models and types. Narrowing them will be helpful. Research both online and offline by dealers. Know the value of the second hand car in the market.

Bringing a mechanic along is always a good strategy. Make sure your mechanic inspects the totality of the car, from the history down to its last screw.

It should be parked on a level spot. You should make certain that it was driven for about an hour. This should make it a good time to make the inspection. Always make it on a well lit surrounding and in broad daylight.

How to inspect it thoroughly:

Checking the exterior Walk around to see if there is damage to the body.The corners of the 4WD should shaken and bounced up and down to see if the shock absorbers are still in good condition.Make sure that the wheel bearings do not make any sound when trying to pull the front tires by tugging them. Open the doors lift the hood and the trunk to see if all the rubber seals are still in place. This will also tell if there's anything loose around the hinges. Check for signs of repaint.There will be difference in the color because shops can never duplicate the original paint of the vehicles. Ask someone to turn on all the lights outside of the car and look if all are working.Vehicles with only 30,000 miles of travel must still have its original tires.Beware if you find a vehicles with only a few miles of travel but has new tires.When the test drive is done, check the discs of the brakes, this should still be clean and smooth.Check the windshield for cracks.

Checking the Interior Though it sounds odd, smell the insides of the car.Sniff under mats and the carpet.If it smells like mildew then it's a sign that there is a leak somewhere or that the car may have undergone flood damage. Switch on the air-conditioning to make sure that it really turns the whole inside of the car cold. Try out all lights inside as well and never forget to blow the horn.Also try all the seat adjustments.The upholstery should still be in good shape too. There will be a lot more to check and here is where the mechanic can help Checking under the hood.Feel the wiring for any cracks or brittleness.Squeeze the hoses and the fan belt for any cuts and possible electrical tape patches. Do not take off the cap of the radiator until its cool enough.The greenish color indicates a good condition where the coolant is.Beware of stains and dirty-whitish color on the radiator.Again, let the rest be checked by the mechanic like the batteries.

Checking under the vehicles Lie down if you must and use an emergency light to see the engine underneath. Feel any signs of residue.Check the pipes and examine any possibility of heavy rusting.The owner or dealer should not stop a buyer from going over about twenty minutes of test drive.This is a special time to thoroughly look for any problems with the air-conditioning,heater, steering wheel, brakes, transmission, and most importantly,the comfort.Feel everything; it’s okay to try it on a hump or a slight bumpy road to really experience the performance. Listen carefully to check any rattles. Have a pen and paper,flashlight,gloves,magnet,towel,blanket and even CD or tape when checking a vehicles out.
