The fuel consumption of a car will increase inexplicably after driving for a long time. Many drivers mistakenly think that it is the cause of the natural aging of the car. It is not. The culprit is the following situations, secretly “eating” your oil.
Tires
Don’t think that tires have nothing to do with fuel consumption, when tire pressure is too low When the tire and the ground contact area is too large, it is when the tire wear is more serious, which not only increases the fuel consumption, but also has the danger of a tire blowout.
Carbon deposits on spark plugs
If carbon deposits on spark plugs increase or deteriorate, It is more difficult to ignite the car, which leads to an increase in fuel consumption. It is recommended to clean it every 3~4 kilometers, or replace the spark plug regularly.
Air intake system
The car air intake system consists of air filter, air flow It consists of meter, throttle valve, intake pressure sensor, air valve, etc. The air filter and throttle valve also need to be replaced regularly, otherwise the air intake effect of the car is not good and the fuel is wasted.
Insufficient amount of lubricating oil
Too much lubricating oil, oil is involved in combustion, The combustion of the mixture is incomplete, carbon deposits on the spark plugs, mufflers, etc., the fuel consumption increases, the growth rate is slow, and the power decreases; too little lubricating oil will cause dry friction between the fittings, which will cause the engine to overheat, reduce power, and increase fuel consumption.
There are many reasons for the increase in fuel consumption. If there is a problem, it must be solved quickly, otherwise the more and more consumption, the more and more expensive, So be sure to pay more attention!
