Understanding Compression Ratio

The compression ratio of an engine is the ratio of the volume of the combustion chamber when the piston is at the bottom of its stroke to the volume of the combustion chamber when the piston is at the top of its stroke. The higher the compression ratio, the more power the engine can produce. However, higher compression ratios also require higher octane fuel to prevent knocking.

What is Knocking?

Knocking is the sound that occurs when the air/fuel mixture in the engine ignites before the spark plug fires. This can cause damage to the engine and reduce its performance. Higher octane fuels are more resistant to knocking, which is why they are recommended for engines with higher compression ratios.

Recommended Octane for 11.5 Compression Ratio

An 11.5 compression ratio engine requires premium fuel with an octane rating of at least 91. This will prevent knocking and ensure that your engine is running smoothly and producing optimal power.
