I have access to several grades of diff fluids. Dino & syn. I use GL-6 90w. Straight 90w is next to impossible (around here in CA) to find at your basic parts store these days. Its always 80-90, 85-90, etc. Multi -vis stuff. Since some of the vehicles I deal with use straight 90w, I can get it. I am sure more opinions will follow.
