How much Sea Foam should I add to my crankcase oil?

How Much In OIl ICON

  • Add 1 to 1.5 ounces of Sea Foam to each quart of crankcase oil for all 4-cycle gasoline, rotary, and diesel engines. Use in all types of conventional and synthetic motor oils.
  • One can of Sea Foam treats up to 16 quarts of motor oil. Most cars and trucks have 5 and 6-quart oil systems: half a can will treat 5 or 6 quarts of oil.
  • Sea Foam only contains petroleum-based ingredients. Unlike some additives, it does NOT include detergents or chemicals that can harm your engine.

When should I add Sea Foam to my oil?

  • Sea Foam can be added to your engine oil as often as every oil change interval – just pour into your engine’s oil filler neck!
  • For routine crankcase cleaning, add Sea Foam to your engine’s oil (into the oil filler neck) 100 to 300 drive miles before a scheduled oil and filter change.
  • Check your oil regularly for clarity. Whenever it becomes dirty (goes from clear to dark), change the oil and filter.
