Naturally, car maintenance is inseparable from the maintenance, but in the face of the dazzling variety of lubricants on the market today, how to choose the right lubricant for your car has become a major challenge for consumers. So some owners simply think that the more expensive the better, every time you change the lubricating oil to spend a little money. In fact, the choice of lubricants should be compatible with the performance of their own vehicles, high-end luxury sedan engine is very sophisticated, high degree of reinforcement, high-grade lubricants should be used; general vehicle selection is slightly lower, but it is no harm, but also be cautious to buy To prevent the use of counterfeit and inferior products. The key to maintenance is to provide regular maintenance and regular replacement of lubricants as specified in the vehicle specification. Here we point out some points of attention when selecting lubricants and hope to help you.

1, gasoline engine oil can not be used for diesel engines. Can not use special gasoline engine oil instead of diesel engine oil, so as not to accelerate the wear of the diesel engine. Gasoline engine oil and diesel engine oil should be used differently in principle. They can only be used on behalf of or in the indicated level range when there are substitute instructions or general oils for gasoline engines and diesel engines.

2. The oil viscosity should be as small as possible. To ensure reliable lubrication of the engine, the oil viscosity is as small as possible. The high viscosity engine oil is only suitable for some severely worn engines except for the southern summer. The blind selection of high-viscosity oil increases the resistance of the engine during operation, thereby increasing fuel consumption. The use of oil with too low viscosity may cause the oil pressure to be too low, the lubricant film strength is insufficient, and the seal is not strict. Therefore, it is necessary to properly select engine oil according to the vehicle condition and season.

3, adhere to the principle of economic application. When selecting the oil level of use, premium engine oil can be used on less demanding engines, but excessive degraded use is not economical. Do not use the lower grade oil in the more demanding engine, otherwise it will cause early engine wear and damage.

4, should try to use multi-grade oil. The multi-grade oil has good viscosity and temperature performance, and has a long use time in the engine, saves fuel, and is versatile for all seasons and is easy to manage. When multi-grade oils are used, the oil color tends to darken and the oil pressure is less than that of ordinary oil. These are normal phenomena and do not affect the use.

5. Brand Selection When choosing a lubricant brand, we should try our best to choose a quality brand, technology, and after-sales service to improve the quality of the brand, because they not only have good technology, but after a long-term market inspection, product quality can be guaranteed.

If the engine is the "heart" of the car, then the lubricating oil is equivalent to the blood of this heart, so the correct selection of lubricating oil is very important to ensure the normal operation of the car and prolong the service life of the car.
