1.Frequently run at high speeds, and add a bottle of special gasoline additives for every 25,000 kilometers run. It can prevent carbon deposition and prolong the life of the engine oil seal.

2. Clean the throttle every 10,000 kilometers, clean the idle valve every 20,000 kilometers, and use the pipeline for engine exhaust gas. It can ensure the normal operation of the engine.

3. Change the antifreeze every two years, and change the automatic transmission oil every five years.

4. In fact, the best way to maintain the car is to wash the car frequently and wipe off the dust in the engine compartment with a wet rag, which can ensure that many parts will not affect the normal performance due to excessive dust.

5. Spend 100 yuan every 50,000 kilometers to inject a hanging needle into the engine and clean the fuel injector.

Hello! The automotive engine maintenance project mainly covers the following aspects:

Engine DAO oil change. One of the requirements for engine maintenance is to change the oil regularly. After a long period of use in the engine, the old engine oil will be oxidized and deteriorated.

If not replaced in time, the old engine oil will not provide enough protection and will not be good for the health of the engine.

Cleaning of grease inside the engine. After a long period of use, there must be a lot of oil dirt inside the engine. Oil scale builds up in the crevices inside the engine and can eventually cause blockages in small lines. Therefore, it is necessary to clean the grease regularly.

Replace engine filters and consumables. The stable operation of the engine requires not only the protective lubrication of the engine oil, but also the coordinated cooperation of various filter elements. Both air and machine filters need to be updated regularly.

Please refer to the maintenance manual for your specific vehicle model. Hope.

1. Regularly change the engine oil: the engine oil is the lubricant of the engine, which can lubricate, clean, cool, seal, reduce wear and other functions of the engine, and is also the "blood" of the engine. Failure to change the oil for a long time can lead to severe wear and tear on engine parts, reducing the life of the engine.

The manufacturer recommends replacing it every 5,000 or 10,000 kilometers. Therefore, when it comes to choosing a motor oil, it is necessary to choose a good quality.

2. Regularly change the three filters: the three filters refer to the air filter, oil filter and gasoline filter. The three filters can provide the engine with the effect of filtering impurities, protect the engine, and also improve the working efficiency of the engine.

The regular maintenance interval of the three filters is the same as that of the engine oil.

3. Battery: The battery is used to ensure that the engine can start normally, and the color of the "electric eye" should be checked in the observation window at the upper part of the battery to see whether it is green. The battery life is generally about two years, and the life may be shorter in cold weather.

4. Brake fluid: Brake is very important for driving safety, brake fluid has strong water absorption, can automatically absorb moisture in the air. Therefore, it is necessary to check the level of brake fluid regularly, and add or replace it in time if it is lower than the standard value.

5. Coolant: The coolant is to ensure the normal operation of the engine, and it is necessary to regularly check whether the coolant level is at the standard value, and regularly check whether the coolant pot is leaking, and the coolant needs to be replaced once a year on average. How do you add coolant?

6. Power steering fluid: Power steering fluid is commonly known as direction oil, and it is necessary to regularly check whether there is any leakage or obvious abnormal noise. Electronically assisted models are maintenance-free, so there is no need to change the steering oil. The maintenance interval of directional oil is about 60,000 kilometers.
