Searched and search on this, and came up with gigantic thread after thread referencing links that no longer are active. Pennzoil documentation doesn't explicitly say Gen 2 (could be either or). So I ask the experts here, is it or is it not Dexos Gen 2? Reason I ask is Walmart is having a sale PUP, plus Pennzoil is running a rebate on 5 quart jugs.
