  • Better performance: Cars with high-compression engines can take advantage of 93 octane fuel for better performance
  • Reduced engine knock: Higher octane fuel reduces the chance of engine knock and pre-ignition, especially in forced induction engines

Engine Efficiency and Compression

Higher octane fuels, like 93 octane, withstand higher compression before detonating. This allows for better engine efficiency and performance in high-compression engines.

Example: Performance cars like Porsches and Lamborghinis typically require high-octane fuel due to their high compression ratios (12:1 or greater).

Engine Knock and Pre-Ignition

Engine knock or knocking happens when the air-fuel mixture detonates prematurely in the engine.

This can lead to engine damage if left unchecked. Higher octane fuels, like 93 octane, resist engine knock and pre-ignition more effectively.

Knock Sensors: Vehicles with knock sensors can automatically adjust timing and air-fuel ratios to accommodate lower octane fuel, potentially preventing engine damage.
