All mileage is in kilometers not miles. Switched to fill of RedLine Heavy ShockProof since mechanic said the fluid looked bad at pre-track inspection.
The previous fill was: "SAE 75W-90 Synthetic Axle Lubricant (GM Part No. 89021677, in Canada 89021678)" (quoted from manual)
Plan going forward in about 3 months and 3k miles (and 11 track days later), switch back to RedLine 75W90 for the winter, thoughts on that?
The report below has 2 track days on it and it had 4oz of GM limited slip additive added (even though it comes already with additive to combat chatter experienced by others with similar diffs):
