Your Cougar turns driving from a chore to a pleasure. Treat it with the respect it deserves with an engine oil flush for Mercury Cougar from AutoZone. The oil you put into your car is rated by both grade and viscosity, or how thick the oil is. Modern oils also come with detergent additives to keep your engine clean and free of gunk and sludge. Visit a local AutoZone to confer with our trustworthy staff and ask about our Loan-a-Tool program if you like to do your own auto work.
