Gear Lube: Mobil 1 or MotorCraft?

Called my local dealer for some prices.... $21.04/qt for the 75-140 syn gear lube!!!! I can get Mobil 1 75-140 for $16.99/qt. Which do you guys think is better? They want $4.99 for the LSD additive and $22.50 for the cover sealant!!

I'm in the same position, I went around town looking for some gear lube, best deal I can find was at Wally's, it was like $7 a bottle for synthetic but they didn't have it in 75-140!...and Mobil1 is 16.99...im just going to order up some Amsoil, its the same price as mobil1 or valvoline....actually cheaper if you have a premium membership with them.

Royal Purple doesn't require the LS addititive and has been working just fine for me.

Your truck is like brand new dude!!! How many miles? I didnt change mine till 60000. But maybe, switching to a heavy full synthetic is the way to save the axle and gears for the long haul. One suggestion, go and add an aftermarket cover. Aluminum will shead the heat much faster than steel. I hear that the '08 Superduty finned aluminum cover will fit earlier axles. I don't think it holds extra fluid, but with the extra finns and cooler running temps, you should be good to go. Dawg nabit!!!! Now I want to change my fluid. SEE WHAT YOU STARTED!!!! Good luck.

haha.. yea i have 17k on my truck. What started all this was I was doing my inspection checklist items which I'll admit haven't been doing and checked the rear fluid gear lube and it looked like crap and I found a piece of metal stuck to the magnet. So I had to pull the cover off to inspect the teeth and sleep easy.... turns out the gears look great, the spider gears look good... everything looks fine. So I'm assuming it was a piece of assembly debre. So I put 80-90 Semi Syn Valvoline in it for the time being.... see how it looks in about 3k miles. But I'm planning on doing the 2008 Cover, with the Ford sealant. Just not sure what 75w-140 to run, and if the LSD additive is needed.
