That's correct, but when I did a drain & fill on my niece's '06 Fusion, which uses the same transaxle, at 30,000 miles the fluid was already turning dark. I would not want to see what it looks like after 150,000, if it would even make it that far.
Oh, I'm not suggesting to leave it in that long, I just doubt they'd spec a fluid with a GI/II base oil for that sorta distance

Weird, my local dealer has it for $5.50? That said, I've never seen the Mobil fluid for anything close to that price, so I'd question whether or not it's the same as the Mobil fluid.
The PDS refers to it as a "hydrotreated oil" so my guess is that it's as "synthetic" as Max Life. That's really my only point. I have no idea of the composition of the Mobil stuff, but I don't think anyone else does, either...
