I wonder which applications
The fill procedure, while tedious and annoying isn't all that hard.
I have Amsoil ATL in my 07 4Runner for almost 40k (so far) and I haven't noted anything out of the ordinary.
I do tow some and when I removed the OE WS @ 45k I was disappointed. The color was almost pure brown (I know... That means very little) but the smell was pure burnt!
I did the fluid level check procedure a couple of weeks ago and the ATL still looks
and smells good.
I'm not suggesting you avoid WS I'm just saying the ATL seems to be a good alternative.
