Yes! When added to crankcase oil, Sea Foam Motor Treatment will reliquify heavier sludge and oil deposits so the crud can drain away when you change your oil. Add 1 oz of Sea Foam Motor Treatment per quart of oil about 100-300 miles before each oil change and it will progressively clean away the sludge. High Mileage works very well for this, too. Hope that helps!
