To my knowledge, Toyota motors don't have such unique designs that require (at least, theoretically) specific oil characteristics, and yet they contract Exxon/Moil to produce their TGMO. Other manufacturers, like VW, (I think) Porsche, etc., DO have unique "specs" (again, at least, theoretically) that oils have to comply with in order to be approved for their use. However, VW, Porsche, etc., don't have their own "brand" of oil (do they?) when you go to buy oil at their Dealership.
Similarly, why does Toyota contract with (???) to make Toyota WS automatic transmission fluid?
Do these manufacturers, like Toyota (etc.), actually make money from the sales of "their" unique oil, transmission fluid, etc., and that's what their motivating factor is...money? Is it just that simple?
