How much fuel is needed for 400 kilometers?

[CharlieAnn]

Approximately 18L of fuel is needed for 400 kilometers. Factors affecting fuel consumption: Air conditioning has a significant impact on a car's fuel consumption. Vehicle weight also notably affects fuel consumption, and tires along with tire pressure similarly influence fuel efficiency. Fuel-saving methods: Regularly check the tire system; insufficient tire pressure increases friction between the tires and the ground, leading to higher fuel consumption. Therefore, it's important to frequently check tire pressure, as different car models and tires have varying standard pressure levels. Also, regularly inspect the braking system, as some cars may experience slight brake drag, which increases the vehicle's load during driving and raises fuel consumption. Hence, periodic checks are necessary. Reduce load by minimizing unused items in the trunk to lower fuel consumption.
