Why is the fuel consumption of new cars high?

For the newly bought car, the running resistance of the engine is greater than that of the running-in car, because the parts in the engine of the new car have not been fully run-in, and the gaps between the parts are relatively small.

So you can be patient and wait until after the first insurance to see if the fuel consumption will change. If the fuel consumption after the running-in period is higher than before, it may be that the fuel injector and throttle valve are too dirty to be cleaned in time.

2. Poor oil circuit

The main reason why the oil circuit is not smooth when the engine has too much carbon deposit, and the main reason why the engine has too much carbon deposit in a short period of time is the use of inappropriate oil products.

3. Improper driving habits

If you step on the accelerator with your big foot or brake frequently during driving, the fuel consumption of the car will increase, and if you start, refuel and shift gears at a normal pace, you can save a lot of oil over time. In addition, master the following distance between you and the car in front and try to reduce unnecessary braking action.

4. Vehicle overload

For car owners who just bought a new car, many people like to stick various decorations and appearance parts on the car, and even worse, they simply move their offices and homes to the car, which increases the fuel consumption of the car. It is reported that the self-weight of the vehicle will increase and the fuel consumption will increase accordingly. Therefore, it is necessary to minimize the load of the vehicle and clean up the items that are not commonly used in the trunk in time.

5. The air filter element is too dirty.

The air filter must be replaced regularly when the vehicle is in use. If it is not replaced for a long time, it will become dirty and greasy, which will affect the use and send an error message to the engine control unit, resulting in insufficient fuel combustion and increased carbon deposition in the engine.

6. The tire pressure is abnormal

According to statistics, when the tire is under-inflated, it will affect fuel consumption. When the tire pressure is too low, the contact area between the tire and the ground will increase, the driving resistance will be greater, and the vehicle will naturally waste more oil.
