Has anyone ever done a VOA on this oil yet? I searched I haven't found one on here yet? I've also searched other forums. And I know, Warren / Highland produces Amazon also Supertech but each oil has their own additive package. So I was just curious if there was one floating around for this one.. As my local Costco has finally gotten 5W-20 back in again.. But I haven't purchased it again..
Thank you
