Car Repairman Interview Question:

Tell us why Does A Compression Engine Use High –octane Fuel?

Submitted by: Muhammad

The property of a fuel, which describes how fuel will or will not self-ignite, is called the octane number or just octane. Engines with low compression ratios can use fuels with lower octane number, but high compression engines must use high-octane fuels to avoid self-ignition and knock.
