The car is repaired in three points and maintained in seven, and many old drivers know it. But knowing that it may not be done, many car breakdowns are not "broken", but caused by inadequate maintenance or careless maintenance. Taking the oil change as an example, different vehicles use different types of engine oil, even if it is the same model of car, due to the different environment, working conditions, and vehicle conditions used by the car, the oil requirements may be different. So today's article will tell you about a few points to pay attention to when changing the engine oil, for reference only.
1. Cars in good condition should be given priority to change the engine oil according to the vehicle maintenance manual. If your car is in good condition and has not been overhauled, it is a good way to choose the oil according to the vehicle maintenance manual and replace it regularly.
2. Cars that are older, have overhauled the engine, and run at high speed all year round can use engine oil with higher viscosity. In the case of normal use of private cars, cars that are more than 8 years old are considered to be relatively large vehicles, and at this time, the wear and tear of the internal parts of the engine may be relatively large, and the large viscosity oil can be replaced according to the specific situation, so as to avoid the problem of large oil consumption caused by serious wear and tear of some vehicles. The high viscosity engine oil here refers to: for example, the original use of 5W20 engine oil can properly use 5W30 engine oil, and the original use of 5W30 engine oil can use 5W40 engine oil, do not jump directly from 20 viscosity to 40 viscosity, which may cause risks such as dry friction and cylinder pulling due to excessive viscosity of the engine oil.
3. If conditions permit, try to use fully synthetic engine oil. Some car owners feel that the price of fully synthetic engine oil is high, their car is not a high-end model, the cheaper the price in the maintenance, the better, this is likely to use inferior engine oil, if coupled with the oil replacement is not timely, the oil deteriorates and fails, the engine sludge and carbon deposition are serious, seriously shortening the service life of the car. The price of fully synthetic engine oil of many brands of engine oil is not expensive, and Dihang lubricating oil insists on being the "porter" of engine oil, and has always been committed to providing customers with cost-effective quality engine oil, and the price of fully synthetic engine oil is better than that of many brands in the case of the same quality.
4. China VI vehicles must use low ash engine oil. With the arrival of the China VI era, the aftertreatment system (exhaust system) of many models has become more complex than before, and most of them are equipped with particle traps, and if the particle traps are blocked, cleaning or maintenance costs are very high. To avoid blockage of the trapper, look for the ACEA standard of engine oil, and have the ACEAC grade mark, it can be used in the National VI model.
Car oil change is a regular item of vehicle maintenance, pay attention to the above points, accurate oil use, in order to effectively extend the service life of the vehicle, so that the car better serve us!
