I am getting close to doing the same. Most synthetics already have the Limited-Slip additive in it and do not need the Motorcraft stuff. I am thinking of doing Amsoil, Mobil 1 or Valvoline in mine and they all include the limited-slip additive. I'd stick with the 75w-140 for the rear and the 80w-90 in the front but that's just me.

You can also get them online from Summit, including the front without the friction modifier in it. Redline sells the fluid without it (NS).

I also put down the amount needed, but hopefully someone will sanity check it for me if I come up short.

Front - 80w/90 - 3 qt - $14.95 each, $44.85 total - Red Line Synthetic Oil 58304 - Red Line Synthetic Gear Oil - Overview - SummitRacing.com

Rear - 75w/140 - 4 qt - $15.95 each, $63.80 total - Red Line Synthetic Oil 57914 - Red Line Synthetic Gear Oil - Overview - SummitRacing.com

Came out to $108.65, including shipping. Just an option.

Can you use Ford's friction modifier with Redline's 75w140?

And can you get away with using 3 quarts of gear oil or better to get 4 quarts?? I just brough up an old thread and missed this one, my bad lol

I also ready I think by S. Carlson that you can use the 75w140 in the front just with NO friction modifier. Can anyone confirm?

I think so but what I am running into is most if not all SYN fluids have Friction Additive already in them...

So far my plan is to get Valvoline Synthetic 75w-140 for the rear (4 @ 12.99) , and 75w-90 for the front. (3 @ 9.99) at Autozone.
