Just curious as to which you guys would use if there was the same amount of each on store shelves. We have the Mobil Super 5000 as our bulk oil at my work. I am actually going to use the Mobil Super 5000 in my other two vehicles beside the Chevy truck. My father up north says at the wal marts near him, there is still nextgen oil, just in a white jug, not a green jug. I would use it myself and I have used Pennzoil conventional before. Let me hear your thoughts and opinions.
