We think the super class of oils as 40 weights, but they really aren't. Those 0w40's that are thin for weight PUP and M1, are really 30 weights and that was always the goal. The oil companies can't add the good stuff to 30 weights, so they make 40 weights as thin as they can in order to add the goodies, knowing because they are 0 ratings they will shear down to 30 weights, and be the best 30 weight you can get. They may start out 40 weights barely, they will be 30 soon, and with the zero winter rating you get good cold properties. This is why I call them super class, special stuff. Guys are afraid to run it because OMG 40 weights are thick, but this is a different type of 40 weight. PUP 0w40 is da ****!
