I have a 2014 Nissian Pather Finder 6 cylinder 102. There is some valve noise. As I am wanting to keep the car and run it 200 thousand miles minimum, I took it to a sports car shop to have it checked over. It got a clean bill of health. To quiet the valve noise they recommended adding Sea Foam Motor Treatment to the oil. I see all the information online is for fuel treatment. Is there an oil treatment? The recommendation was add Sea Foam Motor Treatment to the oil, run 20 miles, get a oil change, and them start using synthetic oil. Is there a different oil treatment? What are your comments on their recommendation? Would Sea Foam Motor Treatment added to the oil as the shop recommended be appropriate?
