Quadrasteer fluid?

[tmundal]

Anyone know of a suitable replacement?

Amsoil says their 75w90 SVG meets all the specs. I have M1 75w90LS.

Is that the QS4 option?

I have used the SVG for years and have it in my 2008 GMC 4x4.

SVG quiets them down real well. We saw it work wonders in an abused 05 Denali. Good stuff. M1 75W90LS probably won't do you wrong.

I'm dragging up a really old post here...

I tried the SVG in my Quadrasteer once many years ago, and it made matters worse. I went back to the GM Quadrasteer Fluid and the groan went away again.

All the other QS owners I've talked to will tell you the same thing... GM Quadrasteer fluid only.
