How It Works

  • Add to crankcase 100 to 300 miles before every oil change – twist off the oil filler cap & just pour it in!
  • Works to re-liquefy harmful oil residues & deposits WHILE YOU DRIVE!
  • Use every interval to help prevent the common causes of oil burning and oil flow issues


Regardless of oil blend quality, no motor oil is able to clean its own residue buildup or contaminants that form as oil breaks down. Adding Sea Foam to oil on a regular basis will go a long way to keeping your engine crankcase and piston rings clean from harmful buildup, helping your engine run better and last longer.


For cleaning oil residues and deposits, add one ounce of Sea Foam or High Mileage for each quart of oil. Safe and easy to use in all types of conventional and synthetic motor oils, gas and diesel. Sea Foam does NOT contain harsh detergents or chemicals that can harm engine seals and components. Will not alter viscosity.
