Car lubricant teach you how to save fuel?

The cost of car maintenance is higher than others, a large part of the reason is that owners will make the following 9 mistakes, the next car lubricant is to talk about how to save fuel?

1, dirty air filtration will damage the engine intake system

If the air filter is too dirty, it will lead to poor air intake, too much dust impurities into the oil cylinder, aggravating the wear of parts, increasing the possibility of trouble; If severe congestion, will also lead to the normal operation of the vehicle. 20,000km or 1 year air conditioning filter is necessary for timely cleaning and maintenance.

2, oil for a long time does not damage the smooth system

Irregular replacement of oil will lead to excessively high temperature of the engine piston. After oil disintegration, it is easy to lead to overheating and melting of the piston and to shorten the service life of the cylinder and damage the engine.

3. The cleaning method of engine room is not proper

Some motorists are wrong to think that the engine compartment can be extensively cleaned with water cannons. Especially after the car has just driven for a period of time, the engine cylinder is in a high temperature condition, at this time the cold water will make the cylinder "excited" although the car engine cylinder is now made of pressurized cast iron or aluminum, not as easy to crack as the general cast iron. But even then, we should not flush hot nacelle to avoid shortening its service life. And, when the engine room is washed with water at high temperature, a lot of water vapor will occur. If the water vapor penetrates into the circuit and the safety and other equipment, the damage to the car can be large or small.

4, the engine fault light is not timely check and repair

The engine fault alarm light is not repaired in time, and the engine fault light is on. Generally, if there is no particularly significant fault, it is still possible to be careful at low speed. It may be some minor faults, but if the engine has significant faults such as abnormal sound severe, vibration severe, engine smoke, etc., must not go on the road, it is best to contact the repair shop or wait for rescue.

5, with air conditioning car damage engine

Check whether the air conditioner is turned on before starting the vehicle to avoid the engine starting with the load of air conditioning. The correct approach is to start the vehicle for two or three minutes, the engine gets smooth, and then turn on the air conditioning.

6, cold car start directly on the road without preheating

Part of the owners of the heat fare comfort cold car to start the engine, cold car engine directly lead to its parts increased resistance, wear, unstable performance, etc., driving it is necessary to preheat the engine to extend the service life.

Overload operation may be severe drag

This is mainly for novice drivers. When driving, we should try to keep the engine speed below the red scale of the tachometer and switch to the appropriate gear in time to avoid overload operation of the engine under high speed. For some manual gear owners, do not drag gear as far as possible when driving.

8, the use of residual antifreeze damage cooling system

Antifreeze on the market is full of beautiful things in eyes, often the quality of good and bad. Some owners do not understand the common sense of this aspect may not pay attention to the quality of coolant, the use of residual antifreeze and comfort to add general water to the water tank. Severe will lead to engine cooling circulation system problems. Auto repair master said that high quality antifreeze is not only low freezing point, and its added ingredients can also inhibit foam, rust, electrolytic and scale prevention.

9, water tank boiling pot at a loss directly add cold water cooling

Some drivers see the water tank "boiling pot" after worrying about the engine temperature rise again, quenching and cold water, which is likely to cause the cylinder head suddenly cold and cracking. After parking, the car owner should let the engine idle heat dissipation and turn over the engine cover for heat dissipation. If a lack of cooling water is found, it should also be increased slowly to prevent the cylinder head from cracking due to sudden cold.
