I know RP usually gets a strong reaction here, but I'm just curious what people think of RP now offering a 0W-40 grade. Spec-wise, it looks almost exactly like M1 0W-40, so we know what they 'set their sites' on in developing the oil. Take a look:

In a way, I don't understand this move, as they already have a 5W-40 grade, although it is a fair bit thicker. Would make more sense to me to invest in a 0W-30 grade, as their 5W-30 has lousy cold-pumping numbers....
