What happens if you fill a car that requires 95 octane with 92 octane gasoline?

[LeAvery]

A car that requires 95 octane gasoline filled with 92 octane may experience knocking or detonation due to the lower fuel octane rating, resulting in reduced power. Here are some relevant details about gasoline octane ratings: 1. First, it's important to understand that the octane rating of gasoline represents its octane number. A higher octane rating indicates a higher octane number, meaning the gasoline has better anti-knock properties. In reality, the octane rating has no relation to the cleanliness of the fuel. 2. Using a higher octane gasoline does not necessarily mean the engine will have more power or better cleaning effects. In fact, using gasoline with an excessively high octane rating can be detrimental to the engine, potentially causing incomplete combustion and leading to more carbon deposits.
