Can you elaborate on this please? I just want to learn the details of the spec/approvals you mentioned. I’m confused what’s going on with the QS euro 5w-40 now that I’ve scratched the surface. The PDS I looked at was from recently this year and SOPUS still labeled it as “Ultimate Durability”. However, every where I’ve looked to purchase some, IE Amazon, it says it’s discontinued or it’s only available with the new labeling, Could be just a packaging design/marketing decision by SOPUS. Seems like they’re price gouging the US market by limiting the in-stock offerings at retailers to PP Euro 5w-40 single qt bottle off the shelf. GTL also isn’t mentioned in the QS literature, from what I’ve seen, although the SDS sheets indicate it’’s clearly GTL. Kinda odd.
