The comment about MaxLife ATF hit home for me, and I imagine it would for those guys that believe their transmissions were possibly damaged by it.
He is probably correct about the testing aspects between the companies as well. I doubt that Ashland has the ability to commit to the extensive testing that BP (Castrol) and Shell have.
I don't think there is any auto manufacturer in Europe that uses their products as OEM, but there are many that use Castrol and Shell especially the transmission products ATF or
MTF.
Size is relative.
Ashland is small as compared to XOM, RDS or BP but it's an 8.4 billion dollar company, 307th on the Fortune 500 list, with 15,000 employees, so it isn't as though the company is too small to develop quality products.
There are many of us who have had very good experience with Valvoline oils and ATFs.
I'm aware of one poster who claims that his automatic transmission failed due to his use of Maxlife ATF.
I don't think that he ever got around to telling what the failure mode actually was, though, so we really have no basis for evaluating his claim.
