I was under the impression that the W rating was the absolute viscosity of the oil. By absolute I mean at some kind of normal engine running temperature and pressure. If Mobil are now giving the W rating in terms of some concocted system that is nothing like a standard then my original point still stands. The mere notion that you can have a standard but you then "modify" it by the oil's ability to pump up in cold weather is just crazy! I was under the impression that 0W has the viscosity of water and that the second number indicates the temperature range. Well it seems that both of these figures are obviously complete bull shit and I will never trust oil companies again.
