What happens if you put 98 gasoline in a car designed for 95?

[LaMolly]

There will be no problem if you put 98 gasoline in a car designed for 95. Here is some additional information: 1. The gasoline grade does not indicate quality, but rather the proportion of isooctane. 2. Different engines have different compression ratios, resulting in varying pressures of the air-fuel mixture. 3. If a high-compression engine uses gasoline with lower anti-knock properties, it may cause knocking, and frequent knocking can damage the engine. 4. Small-displacement naturally aspirated engines are suitable for 92 gasoline, while large-displacement or turbocharged (T) engines with higher compression ratios require 95 or higher grade gasoline.
