Don,
When Sunoco took over from Philips 66 as the NASACAR fuel provider it was all free. But I am not sure that it is now. If you listen to the broadcasters the past year it seems every other word out of their mouth is Sunoco Racing Gas. They never used to mention the gas except that the cars had to make a stop to fuel up. I have looked on the NASCAR site for a long time and I once saw a small blurb that they may have to start paying for fuel about the time they stated talking about going to unleaded fuel.
