The diesel fuel consumption of Great Wall Fengjun 3 and 5 pickup trucks is approximately 7 liters per 100 kilometers.

What does the fuel consumption of a car depend on:

1. If refrigeration and air conditioning are used

2. Driving conditions are the most fuel efficient. at constant speed and at economical speed

3. The lighter the vehicle, the more fuel efficient it is.

4. The more electricity it consumes, the greater the magnetism. generator resistance.

5. Driving habits, braking too much will certainly not save fuel.

6. The best engine temperature is around 70 degrees. If it is too low, the viscosity of the oil. will be high and lubrication will not be good. When the temperature is too high, oil adhesion is poor and lubrication is reduced. At the same time, the cooling fan turns on, which consumes energy and then oil.

7. Engine oil performance

8. Tire strength, wide tires have greater strength and the resistance also increases when they are short of air

9. Aerodynamics of body design
