Yes, you can add Sea Foam to your oil crankcase. It works to clean away (or prevent) harmful oil residue whether sticky varnish or heavier sludge. Add 1 oz of Sea Foam Motor Treatment (or better yet, Sea Foam High Mileage) to your oil crankcase about 100-300 miles before your next oil change. Add it to every oil interval and it will progressively clean away residues. Hope that helps!
