[QUOTE="Johnny O, post: 956899, member: 61743"] As long as it has been properly maintained, a 110,000 mile engine isn't close to being worn out. That said, you won't gain as much in lower wear if you switch to syn now. If it was my truck I'd use Valvoline Max Life 5w-30 and a Motorcraft filter, change it every 5000 miles, and it'll be fine. Dennis' suggestion to use Auto-RX is a good one, although you should use it with regular oil and not high-mileage or synthetic oils. I am running the second Auto-RX cycle in my daughter's Jeep right now. [/QUOTE]
