Changing Axle Oil

Hello, 1988 Turbcoupe, auto. What viscosity is best? Does this require friction modifier?? From dealer only?

I just bought the car, has 74k miles. How often should this oil be changed??

Thanks

Book says hypoid gear lube with 4 oz friction modifier, does not specify viscosity but refers to Ford specification and part numbers. Your parts supplier should be able to offer a recommendation. I don't recall a specific mileage interval for changing the lube in 88 but a more recent Ford requirement is that it be changed at 100,000 mile intervals.

How much oil?? Can this axle be filled by squeezing the bottle using the tapered nozzle??

75w-90 and 3.6 pints with friction modifier

I know the newer 8.8s require 75/140 synthetic and friction modifier.

my lookup said the 75w-90

from what it looks like in the lookup they switched to 75w-140 in 2002 model year in the mustangs

Stinky stuff.....

Where in MI are you from?

I tend to use Mobil 1 in everything, so I suppose Ill go without FM. 4 pints?? wow, thats alot of lube.

I used Royal Purple in the rear, and it requires no friction modifier. It works well for me.
