So what, no one ever said anything about that. However, if you were to
do that and not KNOW that its not an FAA approved part you would be an
idiot. The point is that if anyone says "Oh, wow, auto store parts are
not approved!!" is just an idiot. As I said... "I'm sorry, but there is
just no excluse for buying a part at Autozone and thinking the FAA
would bless it."

It is blessed, because I asked my local FSDO when they came here for a
PACE program. In many places you can buy your oil and filters at Walmart.
