Hi Real. You can add A LOT of Sea Foam to fuel. Considering the size/volume of any auto fuel tank, there aren’t occasions when you might add less then a full can. The best way use Sea Foam in a car’s fuel is when the tank is low, then drive 10 to 20 minutes before adding more fuel. That way you’re able to run the engine with a higher cleaning concentration working through the injectors and upper engine. Hope this helps!
