My opinion, this was the big marketing mistake. If they had brought in Ultra in 0W20 and 0W30, it would have done more to differentiate the product. It also would have opened it up to a lot of Honda and Toyota guys paranoid about their warranty.
The local Walmart near me seems to go through quite a bit of Mobil 1 0W20, since it's the only oil in that weight that it stocks.
