What rear gear oil is better?
Synthetic 75w90 or regular 80w90?
The car sees alot of highway and hot Florida tempatures.
Car is stock

Apparently my ex-husband made that mistake.

It's a frikken rearend dude. Just throw the cheapy brand 80W-90 in it and the friction modifier and call it a day.

How do the clutch plates react to the synthetic oil? Do you get good, even burnout marks?

I would use good, conventional 80/90 and of course the friction modifier... I do tend to
be very cautious, however

Amsoil all the way (with friction modifier). Has anybody heard that Ford now recommends 75w-140 for all 8.8's? Somebody mentioned it on a thread recently, and everybody else just agreed with no questions.

Yup I read that but I was under the impression it was for pick up trucks.
