GM changed the recommendation for the 2019 LT1 as I recall. Mobil makes 0W-40 in ESP dexos 2 certified and European formula. Only the ESP is dexos certified. Unfortunately you’re not likely to find the ESP formulation on the shelf in most retail outlets. If not then you’re fine with 5W-30 dexos certified. There are a few threads about web deals for the 0W-40 ESP if you want to have it on hand for your next oil change.
