Wow, that's great! I've got a 2007 Tundra that uses the WS and before now it seemed that the only place to get it was the dealer.
Now, for the big question - how long before AMSOIL and/or REDLINE produce a WS type ATF?
'97 Mustang 4.6L, '02 Lancer 2.0L, '07 Tundra 5.7L
Please excuse typos - have a 5 year old in lap and am typing with one hand...
