Can 92 gasoline be replaced with 95?
1 Answers
It is possible to use 95 gasoline instead of 92, but to protect the engine, it is not recommended to use higher-grade gasoline for an extended period. Doing so may damage the engine and increase wear. Therefore, it is more scientific and economical to refuel according to the engine's compression ratio or the requirements specified in the vehicle's manual, which also helps maximize engine efficiency. Relevant information about gasoline grades is as follows: 1. The gasoline grade represents the octane rating of the gasoline. For example, 92 gasoline has an octane rating of 92, with n-heptane at 8. 2. Since isooctane has better anti-knock properties and n-heptane has poorer anti-knock properties, a higher grade indicates a higher octane rating, meaning the gasoline has better anti-knock performance.
