I use Maxlife Full Synthetic 5w30 in my 1995 GMC Sierra pickup (216,000 mi). The part number for the quart bottles has been VV179, but I see now that this item is listed as VV155.
Have there been product changes (particularly oil chemistry and performance) that caused the change in part number? I don't see any references to new approvals/certifications or other changes to the product, but I suspect the part number change is indicative of some substantial change to the product offering.
Thank you.

I'll let everyone know what they say.
