I've been running Pennzoil Ultra Platinum 5W-20 in my 5.7 Jeep HEMI V-8 since I bought it new in 2015. Mostly because back then there weren't too many oils that met the Chrysler MS-6395 spec. Now there are several. Because of the supply chain shortage the Pennzoil Ultra Platinum can be hard to find at times.
I noticed today that my Wal-Mart has Castrol Edge Full Synthetic in 5W-20, and it also meets the MS-6395 Chrysler spec. So I was thinking of switching to it. Are any of you guys running this stuff? And what do you think of it?
I don't get the whole "Made From Natural Gas" deal that Pennzoil advertises. But it sure sounds good. I'm wondering how it measures up to the Castrol Edge, which say's, "20,000 miles between oil changes guaranteed"..... Guaranteed what? What say you?
