FAQ

Will it help my car pass an emissions test or turn off the check-engine light? We can't promise that. It's a maintenance additive that helps clean carbon deposits – it does not repair a damaged or failed catalytic converter. If a warning light stays on, have your car checked by a mechanic.

Can I use it in a hybrid or diesel vehicle? No. It's made for gasoline engines only and is not for hybrid vehicles.

How much do I use? One full 4 fl oz bottle is one treatment. Pour it into the tank before you fill up.

How should I store it? Keep the bottle closed in a cool, dry place, out of reach of children.
