i use rotella religiously. I used to do work out at shell research. they test the oils in dyno rooms( a whole lot of them) and in computer monitored company cars. They put alot into it. i ran rotella in all my kubota gen. sets and in all of the series 60 detroits and n-14 cummins that I ran over the road. Never any issues.
Also, I bought this truck at my dealer with 22k miles. The previous owner always got the oil changed at the dealer, but I want to do it myself. The dealer said I could change it myself and still be fine on the warranty, but is he just blowing smoke or is that right? Where should I keep a log of the oil changes?
yes you can change it yourself. I would just start a folder. anything you do to the truck just put the receipts in it. That will help when you go to sell it and you can prove any and all maint. that was done on the vehicle.
