Default Amsoil SVG synthetic gear lube

For those of you who have used this, did you have to also use the GM or Amsoil additive? The Amsoil web site says you don't have to unless your diff starts to chatter.

It looks like Sub answered this question already, but I am curious as to the experience of other Amsoil gearlube users.

Thanks,

Dave

I am using SVG with no extra additive. No problems.

Dave,
As it looks like you saw on another post, I don't use the additive in my Z06 either and I've never experienced diff chatter.

What would it hurt to put in the additive anyway?

It can make your gear lube too slippery in that the clutch disks in your limited slip differential slip too much and make the likelyhood of encountering the one wheel spin in straight line operation greater. The optimum way to add limited slip additive is add just enough to eliminate the moaning, groaning, or chatter noises from the clutch disks. If your LSD is quiet, then no more should be added.

No extra here either. As a matter of fact, I just dumped it the other day to install my DTE rear. I drained the factory fill at 1,000 miles and replaced with Amsoil. I then changed again at 10K miles. The other day I dumped it and it was still blue like the day it went in, not black like rear oil usually gets. I think it was doing a very good job protecting the rear end.

Thanks, everyone. I ordered some on Sunday and wanted to be sure I didn't need the additive. Someone mentioned that 2 pints (1 quart) is all you need. Is that what you guys used?

Is it better to break in a new Diff with conventional fluid and the additive, then change it after 500-1000miles to the amsoil?

"Someone" mentioned wrong...you need 2 QUARTS.

And, actual diff capacity is about 1.7 quarts, so as Hammer also said, you'll need two quarts, not one.
