Can you run Sea Foam in your crankcase on a regular basis? [SOLVED] Asked by Jack L. In Texas Can you run Sea Foam Motor Treatment in your oil crankcase on a regular basis?
Good question, Jack.
Add 1 ounce of Sea Foam per quart of oil to every interval. That will help to clean residues and deposits in the crankcase. You can add it at any time, but we typically recommend adding it 100-300 miles before an oil change. That way everything cleaned by the Sea Foam can be drained away with the old oil. It’s a great way to progressively clean your crankcase and a good preventative maintenance tactic.
Hope that helps!
