Hey, thanks for the much more complete explanation. First off a disclaimer, I've lost a lot of the finer details in the almost decade since I studied this.

Basically what I was trying to get at was that with the periodic heavy loads that most of us will be subjecting our engines to, an oil with a better VI would be more appropriate. Also, by maintaining an oil with similar cold properties you'll ensure the oil stays within the designed operating range of viscosity, even at normal operating temperature. But, the oil won't be as proned to go out side the designed range of viscosity when we start beating on the car.
