Transfer case oil???

I'm changing my transfer case and power steering fluid. Is any Mercon oil from Autozone ok or does it have to be Mercon SP? Some have said Dextron III will work too. Thanks for your help.

Mercon V for power steering.

Some use Mercon V in the transfer case, although Ford does not recommend it.

Spec is Mercon/Dexron III for transfer case.

My '07 manual says to use Mercon in the Xfer case, and between my two Fords, anything that calls for Mercon I've been switching to Mercon V (not sure Mercon is even out there now). I just put V in my Expy's xfer case 2 days ago... That's what I would put in the F350's if it needed it tomorrow -- our Expy is an AWD so the xfer case is always on...

Not sure if I'm helping here or asking for validation from Josh and Cheezit

Motorcraft Transfer Case oil = Mercon/Dexron III

So if one wants to spend $10+ a quart for overglorified T/C oil then by all means buy Motorcraft XL-12.

Says Mercon in my owner's manual every owner's manual for 6.0 truck.

You have Transfer Case Oil because Ford let the license expire for Mercon.

It's no coincidence the license expired with the debut of the 2008 MY Ford trucks and they call for the Transfer Case Oil.
