Any input from anybody would be appreciated? PS Just ordered my LT1 and trying to bring myself up to speed before the car arrives.

I've used Penzoil Ultra Platinum since month #2 in my Camaro...getting rid of the Mobil 1 oil was the first maintenance item I had done. The '18 manual calls for Dexos 1 for all engines...current manuals call for Dexos 2. But since there is zero difference in the engine specs over the years, the Dexos 2 is just a licen$ing play by GM.
Oil changes, along with cabin and air filters, are 3 maintenance items I've never had done at the dealer. 40K miles on it now, uses no oil between the 10 month oil changes.
