Yes, there have been a gazillion 5W-20 vs 5W-30 threads, but this is about a manufacturer's specification. My Jeep owners manual recommends 5W-20 oil, specifically recommending Pennzoil Platinum or Shell Helix. It also states the oil must meet Chrysler MS-6395.
Fine, no el problemo, except while I'm looking at Wally World's Pennzoil Platinum assortment, I see that the 5W-30 (which I use in everything else with 4 wheels) says it meets Chrysler MS-6395 specs - this spec in my owners book is supposedly for 5W-20 ??? Yet the spec seems to include 0W-20, 5W-20, 5W-30, and 10W-30
SO . . . according to this bit of confusion, I can use any of those oil weights and they would be within the 'recommended' specification . . . or is it ? What am I missing here ?
Tanx in advance
