I have been using AMSOIL since my car is new. I have a 2008 MDX and use AMSOIL ATF full synthetic at the transmission and rear differential. For the transfer, I use AMSOIL Severe Gear® 75W-90 which is also full synthetic. For the engine, I use AMSOIL 5W-20 Signature full synthetic also. My MDX is 120K miles now.
