Compression Ratio 10:1, Should I Use 92 or 95?

[OTalia]

Engines with a compression ratio of 10:1 can use both 92 and 95 gasoline. Here are detailed explanations about 92 and 95 gasoline: 1. Engines with a compression ratio of 10:1 can use both 92 and 95 gasoline. If the compression ratio is below 11, it is better to use 92 gasoline, while if it is above 11, 95 gasoline is preferable. 2. The octane number of gasoline only represents a parameter of its anti-knock performance. A higher octane number indicates better anti-knock performance and is not related to purity. 3. The anti-knock performance of gasoline is somewhat related to engine operation. Generally, the compression ratio of household car engines is relatively low, so 92 gasoline with lower anti-knock performance is used.
