Thanks JohnGdole for your great posts! You've certainly given me lots to think about :-)
Do you have a link for the report that showed "significant weight loss (metal corrosion) in lab tests" of the newer pink Toyota Super Long Life coolant? You mentioned the pink Super Long Life isn't as good of a corrosion fighter as the older red Long Life, but the pink Super doesn't have to be replaced every 2 years like the red.
And thanks a million for mentioning that head bolt loosening "glitch."
You also mentioned that Toyota's "Type IV ATF is just a re-labeled conventional (dino) Mobil-3309 ATF. Nothing special about it. For about the same price I'd rather use Mobil-1 Fully Synthetic ATF (the new formulation). I'd think Mobil knows that it's Mobil-1 ATF is compatible with it's dino Mobil-3309." [end quote]
I've been reading that some folks are using Amsoil's Synthetic ATF in place of the Toyota Type IV in their cars. Do you know if the Amsoil synthetic ATF is compatible with the '06 Camry's transmission?
Would it be okay to simply do a drain-and-fill with the Amsoil ATF? This would result in my Camry's ATF fluid being about 40 percent Amsoil and about 60 percent Toyota T-IV, since about 60 percent of the ATF is found in the torque converter, which isn't drained when performing a simple drain and fill. Or would a full flush be required to get all the T-IV ATF out of the car before introducing the Amsoil synthetic ATF?
