RE: Differential Oil?
1) It is ok to use (or switch) to sythetic, its similar to putting sythetic in your engine, what little old oil is mixed will be diluted in the new sythetic oil.
2) I've tried asking about synthetic + friction modifier before and never recieved a strait forward answer, so I'll supply you with what answered my question
Check with which brand you decide to use to see if such disclaimers are issued, if it doesnt specify, i would not use that oil...this is the reason i went with royal purple, good luck

My vehicle has a locking differential. Do I need to add additional friction modifiers when using your Max-Gear®?
No. All viscosities of Max-Gear® are formulated with hypoid friction modifiers necessary for use in clutch or cone type differentials. No additional additives are necessary.

You will still need friction modifier with synthetic oil. i change my diff fluid once a month.all synthetic oil is the same it doesnt matter on brand. if you or you and your boyfriend are gonna do it make sure you wear clothes that you dont mind throwing away afterwords. diff fluid is the worst smell i have come across so far and you will not be able to remove it from anything.

RE: Differential Oil?
ya we will be doing it, but we have a shop to use, so the fluid will go straight to the tank, hopefully avoiding most of the mess and stink. Thanks for the advice I'm gonna go with fully synthetic 80w-90 and a bottle of friction modifier.

It's also what I use. You won't need the friction modifier. Heck, I'm fairly easy on my car and the clutches in the LSD are already fried (fried with the factory crap in it...). I'm pretty much running an open rear end with slippery clutches...until the Detroit comes in, anyway.

It should have the wieght of the oil to use stamped on it.
Mine (2003 GT) says 75W-140 Synthetic I believe.
I used Mobil One Synthetic which says you only need friction modifier for extended applications (or something like that).
I added a bottle anyhow.
BTW the other guy is correct about the synthetic fluid stinking!
It really smells terrible and anything you get it on is ruined.
