I did a google, and found the below web site. Quite interesting
"oil-wise". Talks about cold-start also. Download the "Oil Bible"
(177 pdf pages)...it explains the attributes of motor oil, the
standards,and the testing methods. I now know what the "5"
stands for in 5W30...and it isnt' what I thought it was...

If anyone spots a more authoritive source, I'd appreciate
hearing about it.

Then I saw their definition of viscosity index as ability to maintain
viscosity over a wide range of temperatures.

That was enough for me.
Forget it.
