GM itself recommends diff fluid change every 24 hours of track driving, but does not have any recommendations on oil change interval as far as I know. Perhaps they trust their oil life meter.

When you look at GT-R, the user manual recommends oil change only twice as often for heavy duty (track day) use, and recommends changing it immediately if you hit 280 degrees (?) or above if I recall correctly. So, there you have it. As long as you don't cook your oil, you don't need any of those crazy change intervals, and I don't see why LS3 would be any different

I can agree with that.
