With the high temps seen I'd never run a Dexos1 oil at the track or if you do change it immediately after. Per warranty change it to Dexos2, also ideally put some break-in miles on the oil before the track.
Id inquire at the dealer for Dexos2 oil or order Online from an oil off the approved list.

GM's site does link to this, so it *seems* like we'd be covered if we used an oil from this list even if the packaging does or does not state the dexos2 logo. To be safe I'd also print the list to keep on record with the oil/filter receipts in case/when the list changes.
