Does anyone have experience with the Mobil 1 differential oil 75w140 ? It seems that a lot of the Ford guys are switching to it at the drags.

Thanks >>>>> INTHERED

last year i put in the m1 75w90 as recommended, with the posi additive and never had any issues, in south texas in the summer. i don't know if the 140 may be a little thick for between the plates in the posi. i just switched to royal purple 75w90, again with the gm posi fluid.
