Stanadyne Diesel Fuel Additive

Stanadyne Performance Formula all-season diesel fuel additive, in a 64 oz half-gallon bottle (part 38566, treats up to 250 gallons) for pickups and equipment, or a 5-gallon pail (part 38567, treats up to 2,500 gallons) for fleets, farms and shops. One treatment adds injector detergent, cetane improver, lubricity and cold-weather anti-gel protection, and it is ULSD and B20 compatible.

Poor lubricity and dirty fuel are hard on the pumps and injectors we rebuild, and this is the additive we stock. Compare it in our best diesel fuel additive guide or read the full Stanadyne Performance Formula review. It is a hazmat item, so it ships ground only within the continental U.S.
