I'm getting ready to do my diff fluid and decided to use the GM oil specified for the rear end. GM punished the ZL1 during testing with around 1000 launches to test the strength and durability of the rear end and axles. I figure my spirited street driving is less than their test. Keep the fluid clean and fresh and it should perform. If you track, well that's a different story.
