WHEN PREPARING FUEL AND ENGINES FOR STORAGE, WE RECOMMEND THESE 3 STEPS: #1 Stabilize your Stored Fuel – Use Sea Foam Motor Treatment  Adding Sea Foam Motor Treatment to stored tanks helps fuel resist evaporation, preserves ignition vapors, and prevents the formation of gum and varnish in fuel systems. Gum and varnish residues are the most common cause of poor engine function. Unprotected fuel exposed to oxygen will start to lose its freshness in less than 30 days. Immediately treat any fuel that may not be replenished within 30 days. For fuel storage up to two years, add 10mL of Sea Foam per liter of fuel. #2 Fog your Gasoline Intakes – Use Sea Foam Spray* Sea Foam Spray delivers a high concentration of petroleum lubrication to stored intakes, helping to protect top end parts and seals from wear, dry out, moisture intrusion, or any other cause of corrosion or deterioration. Apply Sea Foam Spray through throttle bodies and carburetor throats. *for Diesel, use Sea Foam in primary fuel filter method #3 Lubricate and Protect your Stored Cylinders – Use Deep Creep Remove spark plugs after fogging intakes. When sprayed into cylinder cavities, Deep Creep coats and protects chambers/cylinders and piston components with petroleum lubrication. Deep Creep resists evaporation and creeps along metal surfaces for optimum coverage. Remember, Sea Foam and Deep Creep are made from highly-refined petroleum and cannot cause harm to an engine. Sea Foam in your tank at all times is always cleaning and lubricating the entire fuel system!
