After doing my brake swap, I refilled the differential with 80W90 instead of what it seems most people here recommend (75W90). What is the difference between the two and is it safe to use 80W90?

did u add the GM friction moddifier?? thats kinda important.. -
yes, im well aware of the additive issue

but anyway... back to my question [img]tongue.gif[/img]Torsen for GM vehicles:
Is it true that the Torsen unit in the production Camaro needs the GM modifier added?
GM issued a technical bulletin adding modifier to the rear axle oil. This was done to quiet what we call a "Rusty Screw" noise that we heard in a very small percentage of vehicles. This does not happen in all cases, however to address owner's concerns we asked that the modifier be used in all instances to insure that the driver would not get this noise. When replacing the fluid it is at the owner's discretion whether or not to add the modifier. Elimination of the modifier does not affect durability of the differential.
