TrueTrac Diff Oil Question

TrueTrac Diff Oil Question
Hey Folks,
Getting my factory LSD replaced with a TrueTrac. Eaton recommends against using synthetic oil, but Ford says to use 75w140 synthetic in the axle. My question is, does Ford recommend the synthetic for protection of the Ring and Pinion or outer bearings? Or is it because of the factory LSD? If I am putting a torsen type unit instead of the factory clutch type, will running Dino 90 weight oil hurt any of the original axle parts?
Okay, that was more than one question... sorry. BUT, I want to choose the best lubricant for the gears and bearings while also getting the most lock-up out of the TrueTrac.
Thank you for any experience with this.

Thanks guys!
I have just read posts until my eyes bled about this and there seems to be no real consensus about it. SOME say that if you don't use the Ford synthetic then the bearings will not get lubricated enough and burn up..... that made me nervous. My gut is telling me what you two have said. A ring and pinion and bearings don't care what gear oil is used as long as it is present.
Next question: I tow heavy about 5 times per year (camping), will I have to change out the Dino based oil often because of this? Or is that NOT considered a "heavy towing" situation by Ford?
Thank you again!

Who are you having do your install? I ask because I'n in your neck of the woods.
I'm still fighting a vibration in my rig that surfaced right after the install. I don't believe it's anything to do with the TruTrac, but, I haven't located the actual source yet. I'll be back on the hunt this weekend.

Okay just got off the phone with Eaton support. His first question to me once I asked was viscosity oil to use in my True Trac was, What part of the Country I lived in! I informed him I was in Canada and he said to use 80W 90 non synthetic oil. I asked him if I lived in a hot area and he stated that if you would have said you lived in a place like Southern California he would have told me to use 90W 140 non synthetic oil. So depending on the temp is what they reccommend. He clearly stated twice to me a non synthetic dyno based oil. Hope this helps! Good luck
