Since a good many Cup races are won on fuel mileage why aren't Cup cars running vacuum advance for fuel mileage when they are under the yellow flag?

Regarding your second topic, that is a VERY good question! Cup cars would definitely get better fuel mileage under cautions if they ran a vacuum advance.
Frankly, I think a lot of the teams are "set in their ways" and very resistant to change. I would be willing to bet that if one team ran a vacuum advance, it wouldn't be long before they won a race on fuel.
