Star brite Stabilizer+ Fuel Storage Concentrate - Available in 8 oz to 16 oz

Star brite Stabilizer+ Fuel Storage Concentrate is an enzyme-based fuel treatment engineered to keep stored gasoline fresh and engine-ready for up to two years. Unlike simple antioxidant stabilizers, Stabilizer+ uses an active enzyme formula that continuously breaks down gum, varnish, and moisture contaminants that form in stored fuel, while built-in corrosion inhibitors coat internal metal surfaces to guard against rust and pitting during long layups. It is formulated to work with all gasoline types, including every ethanol blend as well as non-ethanol gas, making it a dependable choice for boats, motorcycles, lawn and garden equipment, generators, and classic cars that sit idle between uses.

Each bottle is a concentrate, so a small amount treats a large volume of fuel at a simple 1 ounce per 5 gallons ratio. Add it directly to the tank before fueling, or mix it into a gas can, then run the engine briefly to circulate the treated fuel through the system. Whether you are winterizing a boat, storing a mower over the off-season, or keeping a backup generator fuel supply ready to go, Stabilizer+ helps prevent the hard starting, clogged carburetors, and fuel system corrosion that untreated gasoline causes over time.

Sizes & Options

Stabilizer+ Fuel Storage Concentrate is available in two bottle sizes so you can match the amount to how much fuel you need to treat. The 8 oz bottle treats up to 40 gallons of gas and suits smaller fuel systems like mowers, generators, and personal watercraft, or occasional seasonal use. The 16 oz bottle treats up to 80 gallons and is better suited to boats with larger tanks, multiple pieces of equipment, or anyone who wants a season's worth of stabilizer on hand without reordering. Choose based on your total annual fuel volume rather than a single fill-up, since the concentrate stores well until needed.
