A rattle is not a good sound. Not when it comes from your engine.

It’s called ‘knocking’ and means that fuel in the combustion chamber of your engine is igniting uncontrollably. If you use an inferior-quality fuel, deposits will form in the combustion chamber and increase the engine’s octane number requirement (ONR). Knocking happens when the engine’s ONR is higher than the octane rating of the fuel you choose. Even with adjustments to the engine’s spark timing in modern cars, the only foolproof prevention for knocking is to maintain a clean engine.

Techron’s precise polyetheramine-based formula not only removes carbon build-up on these vital engine parts, it keeps working to prevent harmful deposits that can interfere with acceleration. So you’ll enjoy maximum performance with every drive.
