Lucas Oil octane booster is a genuine performance enhancer that protects high compression engines from pre-ignition detonation, pinging and spark knock. This in the end improves acceleration and throttle response. This product is suitable for various engine types such as carbureted, rotary, throttle body and fuel injected engines. Octane boosters are used to modify the rate at which gasoline burns for a stable combustion chamber to release more power and improve performance. The octane booster also prevents lean out conditions by stabilizing the fuel such as the new oxygenated gasoline. Buy yours today, shipping is free.
