Please follow your own "scientific" suggestion and observe some oil (any oil) yourself in a container at 0 degrees C and heated to 100 degrees C. The oil becomes thinner and less viscous as it warms. Don't beleive me? Read this: http://www.engineersedge.com/lubrication/oil_viscosity.htm I know, it was only written by a bunch of silly engineers, but they seem to think that: "Viscosity varies inversely with temperature". Let's look at some empirical data, the specs for one of those dreaded multi-viscosity oils, Mobil Delvac 1 5W40: http://www.mobil.com/USA-English/Lubes/PDS/GLXXENCVLMOMobil_Delvac_1_5W-40.asp Viscosity is measured in Centistokes (cSt) (look it up). Under typical properties for this oil we see the cSt
