Can Sinopec gasoline be mixed with fuel from private gas stations?

[DelClayton]

No. Because the source of fuel from private gas stations is uncertain, it is difficult to avoid adding low-quality fuel, which may have a negative impact on the engine. Introduction to gasoline grades: Gasoline grades represent the anti-knock performance. The higher the grade, the better the anti-knock ability, which has no relation to the quality of the gasoline itself. A higher grade does not mean fewer impurities in the gasoline. Introduction to unleaded gasoline: The main unleaded gasoline grades available in the market are 90, 93, and 97. In major cities, Sinopec also supplies high-clean 90, 93, and 97 unleaded gasoline, which not only has lower lead content but also contains small amounts of additives to clean the fuel system.
