I recently purchased two of the 6 quart Smart Change boxes of the LIFELONG variant of Havoline Full Synthetic 0w20 for $22.97 each from walmart.com to have on hand when it comes time to change the oil in the 2022 Silverado. When I first tried to purchase them, they were out of stock, but 3 or 4 days later it was back in stock.
I know it is not the Havoline Pro DS Full Synthetic 0w20, but the LIFELONG has essentially the same results for the various tests listen on their respective product data sheets, and it does meet the Dexos 1, Gen 2 specs.
I admit that they are a little different, but I doubt the engine will notice it.
