[QUOTE="02BigD, post: 38506, member: 96"] I use Mobile Delvac Super 1300 15w40, and 2 quarts of Lucas [I]Synthetic[/I] oil treatment. I started the Lucas after the motor break in at Carson Stauffer's suggestion. There is a noticeable difference with the injectors being snappier, and the oil feels better to the touch at oil changes. Plan on doing a sample next change, I'm curious to see what comes back with it. Change the oil at 3000, or within 200 miles if I run a little over. On edit; I would run 5000 mile intervals, same oil, with the factory HPOP. Used samples consistently came back good at those intervals. That was stock injectored as well FTR. [/QUOTE]
