Can a car using 95 gasoline switch to 92 gasoline?

[VonViolet]

Car using 95 gasoline cannot switch to 92 gasoline. The following are the reasons why 95 gasoline cannot be replaced with 92 gasoline: 1. The isooctane value ratio of 92 gasoline is much lower than that of 95 gasoline. The higher the octane number, the higher the isooctane value. The higher the isooctane value ratio, the better the anti-knock performance of the gasoline. It has a significant inhibitory effect on carbon deposit formation after combustion. 92 gasoline can be directly replaced with 95 gasoline, as they only differ in isooctane value. In other words, lower octane gasoline can be directly replaced with higher octane gasoline without any additional maintenance operations. However, 95 gasoline cannot be directly replaced with 92 gasoline. 2. The higher the engine's compression ratio, the higher the requirement for gasoline's anti-knock performance. Therefore, generally speaking, engines with high compression ratios need to use gasoline with an octane number of 95 or above and cannot directly switch to 92 gasoline.
