STA-BIL In-Season Protection is a gasoline additive that cleans the fuel system, prevents ethanol corrosion and keeps fuel fresh for up to a year. It is meant for regular in-season use rather than winter storage, and works in any 2-cycle or 4-cycle gas engine: cars, motorcycles, mowers, snow blowers, boats and generators. One ounce treats 5 gallons, so the 8 oz bottle covers about 40 gallons. Compared with storage-only stabilizers, it adds injector and gum cleanup to the same ethanol protection, and owners rate it highly for keeping small engines running clean.

This fuel system treatment and fuel injector cleaner is for gasoline-powered engines. It is safe for all 2-cycle and 4-cycle gas engines. It works in all gasoline blends, including ethanol and non-ethanol fuel.
The formula prevents corrosion caused by ethanol-blended fuel and cleans the fuel system. It also prevents gum and varnish buildup, and it helps increase engine power and fuel efficiency. It keeps gas fresh for up to a year. It can be used in vehicles, motorcycles, lawn mowers, snow blowers, boats, generators and more.
In small engine equipment, pour it directly into the gas can. In a vehicle, add it before adding fresh fuel at the pump. Add it to fuel as soon as you get the fuel, so you know the fuel is fresh.
