[LaEverett]

Using 92 gasoline in a car designed for 95 may cause engine knocking. Here is some relevant information about 95 gasoline: 1. Definition: 95 gasoline consists of 95% isooctane and 5% n-heptane. High-compression engines can also use lower-grade gasoline, but you should not blindly choose gasoline based on the compression ratio. Instead, follow the manufacturer's requirements for refueling. 2. Difference from 92 gasoline: The main difference lies in the octane rating, with no other essential distinctions. 95 gasoline is composed of 5% n-heptane and 95% isooctane, while 92 gasoline consists of 8% n-heptane and 92% isooctane. 95 gasoline has a higher octane rating than 92 gasoline, making it more stable and easier to burn, and it also delivers greater power output compared to 92 gasoline.
