Can I add Sea Foam to the oil in my car to clean out deposits before I change the oil?

Yes! Sea Foam works very well to reliquefy deposits in your oil crankcase.

Here’s what I’d do:

Add 1 oz of Sea Foam per quart of oil around 100-300 miles before your next oil change. That allows all the reliquefied deposits to drain away when you change your oil.

Keep adding Sea Foam at that 100-300 mile mark before your oil changes and it will progressively work to clean your crankcase and keep it that way.
