Mustang 87, I will have to disagree with you. Most new cars come with synthetic oil in them already, or a syntec blend. You want to stay away from oils like Penzoil, and now Quaker State cause they are high in Priffin, which causes a wax like build up "engine sludge", also stay away from FRAM oil filters which contain Teflon by DuPont which DuPont put out a statement saying that the Teflon they manufature is not recommended for use in combustion engines. You usally don't put Synthetic oil in high mileage cars due to seals wearing out. What I would suggest is running a Syntec oil like Kendall, Valvoline. Mobil 1 is a great oil. My mother in law runs it in her 199,000 mile 1998 Volvo. I would run one of them for an oil change, and watch to see if any leaks develop.
