1. Make sure your tires are set to the proper inflation. Properly inflated tires can reduce fuel consumption by up to 3%.
2. Tune up your engine. A properly tuned engine maximizes power and can greatly enhance fuel efficiency.
3. Don't accelerate too quickly. Accelerating smoothly keeps the engine at lower rpm's thus using less fuel.
4. Don't speed. The faster you move the harder your engine has to work to push through the wind. Speeding can reduce fuel efficiency by up to 33%.
5. Check the condition of your engine air filter. A dirty filter will reduce fuel economy.
6. Replace your fuel filter according to your manufacturers recommended schedule. This will go a long way to enhancing fuel efficiency.
7. Avoid excessive idling. Idling a vehicle wastes a significant amount of fuel. The best way to warm up a vehicle is to drive it slowly until it reaches proper operating temperature.
8. Remove excess weight from the truck and/or back seat. An extra 100 pounds reduces fuel consumption by 1-2%.
9. Use cruise control. In most situations using your cruise control reduces fuel consumption by maintaining a constant speed.
10. Although necessary at times, avoid using the air conditioner all the time as it causes the engine to work hard and consume more fuel.
11.Don't use your car for short distances.When a car engine is cold and doesn't have enough time to heat up,it consumes over 50% more than it does in normal driving
