hey guys, I just picked up a used LLY. 30,000mi on the clock, the PO had written the mileage on ALL the filters along with the date it was changed but I have no idea what oil was used. I plan to use this truck as a tow rig only grossing 26K. It might get used once a month, maybe 5,000mi per year but ALWAYS towing heavy.
So what oil? I always ran rotella 15-40 years ago when I had my 01 LB7. I have 10qts of rotella 15-40 sitting around that didn't get used from my ol IDI ford. (RIP) should I just use that for this years oil change or should I run out and pick up some rotella synthetic?
Also, I was thinking of just changing the oil once a year or 5,000mi whatever comes first..
what says the almighty DP?
