Will Sea Foam work on sticking lifters in a 2013 GMC Yukon Denali? [SOLVED]

Thanks for the question! Lifter noise (sticky lifters) can be resolved by using Sea Foam Motor Treatment in the oil crankcase. Sometime the lifter noise goes away quickly, but most of the time requires regular treatments (every oil interval). The big benefit to every interval is to progressively clean away all the old oil residue that builds up as engines add miles. Keep adding Sea Foam (or High Mileage) to your oil! We recommend adding 100 to 300 drive miles before each oil change interval. Add 1 ounce of Sea Foam per quart of oil.
