I thought I read at aone point that Amsoils's group-III's were from Petro-Canada, but I don't think they'd be robust enough for this new application...any ideas, Pabs?
Anyone who says this base oil comes from this supplier and that base oil comes from another supplier don't know what they are talking about. I have talked to the people in charge and they will not disclose that information. They work closely with all base oil and additive suppliers looking for the best products in the marketplace.
The other oil companies are locked into using base oils and additives developed within their companies.
