1, depending on the car, what kind of fuel is good for private cars? Simply put, cars under 30W are all 93 (Beijing 92), and cars over 30W are all 97 (Beijing 95). Of course, you can add 97 to any car (except diesel), but the cost will be high. People over 30W can run after hearing a friend say that they can add 93 once, but the spark plug is still damaged and the maintenance cost will be more expensive, so the car is still at any price, just add the corresponding oil.

2. At present, there are many brands of gasoline on the market, and whether the use of gasoline reaches the standard is closely related to the maintenance of automobiles. Therefore, experts advise car owners not to pursue high-grade gasoline excessively. Whether the use of gasoline meets the standard is closely related to the maintenance of automobiles. Long-term use of low-grade gasoline in high-end cars will cause problems such as damage to internal parts of the engine and seriously shorten the normal life of the engine. Some suppliers take advantage of the car owner's psychology, shouting "a good horse with a good saddle, a good car with good oil" and promoting "high-grade gasoline should be used for long-term maintenance of cars".
