in some ways you are saying the same thing that I did in different words, thickness or "weight" and "strength" are words I'm used to using so people understand it easier. yes the "w" is the thickness when cold, therefore the natural thickness of the oil itself, correct?

if the second number is the thickness when hot, doesn't that also reflect it's ability to not burn at high temperatures? the strength?

however this can be argued as I've read that oil thins out when it heats up. :/ confusing stuff.
No the w is not the natural thickness its the oils viscosity at low tempratures. ie cold starting viscosity.

No the second number doesnt mean its more resistant to burning, it means it wont thin out as much when hot. The reason using a thicker oil makes you burn less oil is it reduces the ammount that can get by the rings, VSS etc due to its higher viscosity.
