Let's say you wanted to thicken up 30 weight Mobil1 a little...

Sure there is! We simply don't "label" them that way. Viscosity's an inclined scale, not a bunch of steps. And since nobody lists xW- vis in a VOA/UOA report, how do we know what happens at the low end?

True, there could be a 35 weight oil, but like you said, I just meant that from a labelling standpoint there is not. One of my big wishes is that the oil companies should list their viscosities on a different scale, so that you could tell exactly how thick the oil is, not just seeing it in a rather vague range like it is now. The difference between an oil that is 9.3cst and another that is 12.4cst is pretty big, but yet both of those oils could be labelled as 30 weight oils.
