Can you use Sea Foam with engine oil? [SOLVED]

Thanks for the question, Joe! Yes, you can use Sea Foam Motor Treatment in oil. Sea Foam reliquefies oil residues and deposits so they can be drained away with the old oil. We recommend adding it 100-300 miles before your next oil change. That gives the Sea Foam enough time to circulate and clean. It also lets you drain away all the reliquefied crud (residues and deposits) when you change your oil.

Add 1 oz of Sea Foam per quart of oil in the crankcase. Do not exceed this ratio.
