What should I do if the Elantra car costs too much gas? I'm an Elantra taxi, and my car consumes too much gas.

Engine power performance decreases, fuel consumption increases, and nozzle is blocked.

Cause of illness: This is probably due to insufficient fuel combustion and increased carbon deposition in the engine due to long-term failure to replace the oil, oil filter and air filter.

Green maintenance: It is recommended to replace the oil and the oil triple filter every 5,000 km, and the air filter and the oil triple filter every 1000 km. Otherwise, impurities in air, fuel and engine oil will cause parts to wear and block the oil circuit, thus affecting the normal operation of the engine.

The fuel system and the three filters have been cleaned, but the engine is still underpowered, the tail gas emits black smoke and the fuel consumption is high.

Cause of disease: It is likely that the dirt of air filtration hinders air circulation, which reduces power and increases fuel consumption.

Green maintenance: The function of air filter is to purify the air entering the cylinder. Dirty air may cause engine performance failure. Therefore, every 1000 to 2000 kilometers, it is necessary to check whether there is dust or water in the air filter and the hose at its lower end, and if there is, it should be maintained in time. The air filter needs to be replaced after driving 10000 km or 1 year.

The fuel consumption of cars is increasing.

Cause of illness: There are many reasons for the increase in fuel consumption. But the most common and easily overlooked is the inspection of tire pressure. Insufficient tire pressure will not only increase driving resistance and fuel consumption, but also affect the service life of tires.

Green maintenance: bring your own tire pressure gauge and check the tire pressure frequently. Don't forget to check the spare tire so as not to find it flat when it is in urgent need of replacement. The tire pressure will be higher than usual when the temperature is high, so it is more accurate to measure the tire pressure in cold weather or in the shade. Generally, the tire position should be changed every 65,438+00,000 kilometers to avoid a big difference in the degree of wear before and after. If it is necessary to replace severely worn tires, it is best to replace two or four tires together, and tires with the same grain can be replaced alternately. In addition, the dotted tire helps to save fuel.
