I think the cost of premium at the pump will grow much faster then race fuel.
I used 4 barrels of race gas between Oct 07 and now. The last one I bought 3 weeks ago. I paid $320.00 for each barrel. From what I was told when I picked up the last barrel demand is down. They offered to sell me 4 barrels at the $320.00 price and said they would store it for me in a cool dark room. I've got between 50 and 52 gallons from each barrel, that's about $6.27 a gallon.
Premium pump gas will be over $7.00 a gallon by Oct.
Remember what the t-shirt says. "If you can't run with the big dogs stay on the porch"
If that holds true it's a no brainer. But are all the pump gas turbos set to run on Premium or are they taking 87?
