Can I use Sea Foam straight in a fuel rail injector cleaning system, or does it have to be mixed with gasoline?

That’s an important question Ron. When using a canister (adapts to fuel rail), you need to mix Sea Foam Motor Treatment with gasoline. We recommend 50/50. Any of the following Sea Foam products are safe to use in virtually any injector cleaning systems used by shops and engine professionals: Sea Foam Motor Treatment, High Mileage, and Marine PRO. Each requires 50/50 mix for gas engine fuel rails. For diesel rails, use straight Sea Foam (no mixing).
