I have been waiting for this for a long time. At one point Mobil 1 pulled thier 0W-20 after going to the EP oil and I dont know if they have one yet again. Im glad to see that Amsoil has come in to put out a product that will fill a niche area of the motor oil market.
I personally dont agree with a 20 weight oil just because its a specification by the manufacturers to meet CAFE requirements, but nonetheless, it appears that the spec is here to stay, and I feel a WHOLE lot more comfortable with an Amsoil 20 weight oil than I would with any other producer.
