I have 60+ thousand miles on 1.5t equinox been using 0w20 since new and have been following OLM for the most part. I’ve used Pennzoil, Royal Purple and Val EP all test and all did fine from 5000 to over 6000 miles . Was told try 8000 next time.
2020 Equinox 1.5T
Miles on vehicle 60160
OCI 4660 and little over 6 mos
Our: Pennzoil Platinum 0w20 Endurance filter
In; M1 EP 0W20, M1 filter
OLM 38%
I’m going on a 1500 trip almost all high speed and didn’t want the OLM going below 20%. And I was going to change the oil again in late Nov or...
I downsized 5 yrs ago and ran into the same problem. My solution was get an oil extractor and a small container for the oil filter which I change every other oil change.
