Did AutoZone discontinue VR1 20w-50???...thoughts on Rotella 15w-40

Well........... I've been using it in my ramp truck for many year's, and have never had any engine problem's at anytime. Matter of fact....... my engine machine shop co-owner, has told me more than a few time's, that Shell
Rotella 15-40W is one of the best oil's out there for heavy duty use. And plus I've known him for many year's, well he will be 75 YO this Tue's, and been grinding crank's for 55 year's, so I take his information seriously, as he has been around the block many time's. And yes, it will boost your oil pressure some, which is alway's a plus, and IMO, will not hurt performance any either, but some may disagree. Good luck with possibly changing your brand.
