I'm due for an oil change in a couple thousand miles and am contemplating my next oil.
I bought this truck with 8848 miles on it in June 2020. Oil was changed before I got it and I changed it at 16504, 26462, 36536 and 46508 with Pennzoil Platinum 5w20. I have yet to add makeup oil on any interval, has lost at most 1/2qt over the entire interval.
Commute is 80% highway, 55 miles round. Almost all family driving is in this truck as well on evenings and weekends. My 2022 mileage was 22858 miles.
My last UOA was slightly questionable but some retesting eased some concerns, but I plan to sample after this oil change.
10000 Mile UOA
With all that said, I'm looking to add a little more buffer to the oil for my intervals. Couple points, I'm going to run 0w20 or 5w20 and I'm going to run til the OLM says 0%.
Ideally, I'll be buying an oil that is readily available, but I'm not opposed to order if necessary.
My first thought is to bump to Pennzoil Ultra Platinum (However, I now see that this seems to be an ordering situation).
