I've got 20,000 miles on my Sienna and am seriously considering purchasing a case of Amsoil ATL and doing 3X drain/fill. Anyone running ATL in a Toyota spec'd for WS ATF?

I have maybe 10-12 customrs running it, with zero issues.
I wouldn't hesitate to use it. I serviced my Toy with Valvoline Maxlife ATF and haven't had any issues. Lots of reputable ATF manufacturers recommend their products for WS replacement so I don't think WS is nearly as special as Toyota makes it out to be. I think they're just trying to avoid warranty "headaches".
Do you have a dipstick and reg oil pan on your Sienna?
