Did you not understand my post?
It is 502 certified.
Yes I completely understood your post. Did you understand mine?
I didn't say anything about some Amsoil oil not being certified to VW 502 specs. I actually posted in the post above yours (post #4), that Amsoil now had some VW approved oils... I said the reason why independent verification is used is to protect consumers because what may be perceived by a boutique oil company as an insignificant formulation change to save money or cover a broader market may be an issue to some engines. There is no means to know without proper independent testing.
