It says all good. oil was Amsoil XL 5w-30 with Wix filter recommended 7500 mile oil. I had 8167 miles on it when tested and changed. 32467 miles total on truck. recomendation field on test says- "no corrective action required. Oil is suitable for continued use. Resample at next regular interval." intervals are 3k miles. guess it turned out pretty good. this time I am going to wait on my results before changing and see how far it can go lol.
I picked it up saterday. no luck with the noise. I noticed last night after driving without the radio for a few miles you can here it inside the cab when the motor is under load.
I've been doing the same thing. I'll be getting my mobil 1 oil retested at 15,000 miles. Only if everyone knew how far you can REAllY go on oil (synthetic or not).
