I've seen the table.

(Actually Lubrizol doesn't market anything ever, as is well known.)
Exactly my point. This is a company who has contracted another company to develop an additive package for them and is using a single test to claim their product is superior despite having absolutely zero factory approvals. It isn't the developer of the additive package claiming it is superior, it is the folks trying to sell the product.

Lubrizol also makes AMSOIL's additive packages. Are we now to extend these claims to their products? Is this performance-by-proxy here? Because that's essentially what you are advocating, that by being associated with Lubrizol that by golly, these things gotta be the bees-knees!

Because they don't need to obviously. It can pass all the requisite OEM approval protocols using the base stock blend they are currently employing. I mean, you are pointing out that Lubrizol is doing the DT40 additive package, so do I need to point out that the additive package for M1 0w-40 is co-developed with Infineum? Oh, and there isn't that same pesky budget like Joe Gibbs would be dealing with when you half-own the bloody company.

His claim was a VW approval was that much. I have no idea how much the Porsche A40 approval is but from the sounds of things these aren't as expensive as many believe they are
