Octane Booster

Penrite Octane Booster is a fuel treatment designed to enhance the octane rating of unleaded octane petrol. It’s formulated to increase the octane rating by up to 2.5 when used at a ratio of 375ml per 50 litres of petrol.

The unique formulation of Penrite Octane Booster improves power & acceleration, enhances fuel economy and prevents engine detonation damage. It reduces “pinging” with low octane fuel and provides protection against valve seat recession. Octane Booster will also keep injectors clean for optimum performance and economy.
