Rear End Additive
I plan on changing rear end fluid pretty soon, do I have to mix an additive with the oil? My dad say's I do, and I can only get it from the dealer.

The Eaton is a little forgiving and IIRC the newer ones (as in the past 8 years)with the carbon fiber clutches don't need the additive. But the Auburn needs only dealer additive, the parts store stuff in a tube does not work.

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.
