A clean fuel system runs better and lasts longer, and STA-BIL's In-Season Protection is built to keep it that way. Poured straight into the tank, it works through the fuel injectors, lines, and pump to clear out water, gum, and varnish that accumulate with regular driving and towing.
Along with cleaning, the formula adds corrosion protection for the internal fuel system components, which matters for a tow vehicle or generator that sits between trips.
Add it at your next fill-up to help your engine run cleaner and protect the fuel system for the long haul.
