Keep fuel fresher, longer for quick engine starts even after extended periods of storage, with Sea Foam® Motor Treatment. Ideal for gas, ethanol, biodiesel, and diesel auto, marine, and fleet engines as well as 2-stroke and 4-stroke engines. When added to fuel, Sea Foam Motor Treatment removes moisture from the fuel to help prevent corrosion and protects the engine from gum and varnish residues. It also cleans injectors and carburetor jets, helping to maximize engine life. This fuel stabilizer adds lubricity, frees up lifters and rings, and acts like a deicer anti-gel. Only contains petroleum-based ingredients—no harsh detergents or abrasive chemicals that can harm your engine or damage fuel-system parts. The more you add to fuel, the better it works to dissolve and clean harmful residues and deposits. Manufacturer model #: SF-16. Keeps fuel fresh, even during extended periods of time.
