Can a Car That Uses 95 Octane Gasoline Use 92 Octane Gasoline?

[LeAlice]

It is possible but not necessary. Here are the differences between 92 and 95 octane gasoline: 1. 92 octane gasoline has slightly lower anti-knock performance compared to 95 octane gasoline. Since engines have different compression ratios, their requirements for gasoline anti-knock performance also vary. Engines with lower compression ratios can use 92 octane gasoline, while those with higher compression ratios require 95 octane gasoline, which has better anti-knock properties. If 92 octane gasoline is used in a high-compression engine, knocking may occur, and frequent knocking can damage the engine. Therefore, it is important to choose the appropriate gasoline grade for your vehicle. 2. Strictly speaking, 92 octane and 95 octane gasoline should not be mixed. However, their chemical compositions and other aspects are relatively similar, and both have strong anti-knock properties. Mixing them generally does not cause significant issues, but to ensure vehicle safety, it is best to use them separately.
