What is meant by the octane number?

The octane number is a measure of a fuels ability to resist detonation. The higher the octane number, the more resistance a fuel will have to detonation. This enables the engine to be more highly tuned and to release more power and / or improve the fuel consumption. The higher the octane number, the better the fuel.

We offer several treatments to boost the octane, such as Millers Petrol Ecomax and Millers Petrol Ecomax One-Shot Boost for modern cars and Millers CVL Turbo for older vehicles.
