Hey everyone,
Been reading around the boards and there seems to be a lot of emphasis on getting only Toyota ATF transmission, differential, etc. oil/fluids ONLY. Cousin just became a head tech at a Lexus dealership here in NYC. Told me that toyota does not make any oils, fluids, etc at all. They buy everything in bulk, whatever is the cheapest they can get. i.e...the transmission or differential fluid is made by Quaker State or valvolne etc, depending who comes in with the cheapest bid.
The only reason why they say toyota on it is for packaging for individual sales and paying a couple of bucks more for nice packaging.
Basically, you can use any brand you want...Mobil, etc., as long the type of oil/fluids used is correct.
Not sure if everyone knew this already, but I just wanted to share something new I learned today.
