i think Hallmark is hitting the mark. This is a way to deal with better quality, new spec oils and dealing with consumers current thoughts of oil prices. If they just sold new spec oil as MC 5K and upped the price, most customers wouldn't know they were getting better oil for more money and wouldn't be happy. To prevent us from comparing apples and oranges, this is their solution. We have been wondering how oil companies were going to deal with SN, and now we have an example of how one company is going about this change. Better product in the bottle for more money, and likely more profit.
