good report - thanks for the post. kudos to the author/photographer!
with high margin and high selling price this is bound to be copied. I've heard that some use recycled oil collected from service centres that are originally bound for industrial use (which are ok for low grade oils).
yes, as with what some are posted try to buy from reputable source. Even though a bit more expensive.
anyone ever ask where SC's source from?

what I dont like is that they can con mechanics too.... not too sure how the supply chain works but I know that salesmen usually travel around to sell this to shops.
