I just got my 1st oil change a while back on my 2004 super duty D. I just found out they messed up and put motorcraft synthetic oil in. I was wanting shell rotella. I was wondering if I change oil now to rotella if it would hurt anything I have 4000 mi. on since they changed it. which means the truck has 9000 on it. Hope someone can help me out with this. Thank You Shortround
Won't do any harm. I switch btw synth & Dino from winter to summer sometimes. Starts better in cold temps w/ the synth. Will run a little quieter on the synth as well. Key is run a good oil & change it when your supposed to.

I hope to get an answer as well. Although, my question is of oil quanity. I have been all through my service manual and vehicle data stickers. I have also been throughout multiple forums within FTE and haven't found the answer.
I just bought a 2001 SD F250 with a 5.4 engine and want to change the oil. I can't find how many quarts I'll need to buy.
