Can you add Sea Foam to the oil in a 2019 Volkswagen Jetta? [SOLVED]

Thanks for the question! Yes, you can add Sea Foam to the oil crankcase. It will clean oil residues and deposits that can restrict oil flow. Add 1 ounce of Sea Foam per quart of oil in the crankcase. I’d recommend putting it in when you are 100-300 miles away from your next oil change. That gives it a chance to circulate and clean, and allows you to drain away all the crud when you change your oil.
