Have run 0w20 (M-1 AFE & QSUD).... in my vehicle for over 4 years now. My engine runs smoothly with no issues. Have had winter temps at times in the -15 area, and it started perfectly each time. OCI's have ranged from 7800 to 9300.
The 0w20 works fine....despite what our lubrication expert Trav says....
