Heads up, the post by Kool Performance was in regards to the Arkansas 1 - Mile Challenge September 28-30 in Blytheville, Arkansas.
They supply VP but it's for whoever wants to purchase it. At Bonneville, it's required to purchase Gas for the Gas classes from the gas vendor ERC fuels (example C/GR would be C motor size, G for gas, and R for roadster. If it were C/FR for Fuel they would not have to buy fuel/gas from ERC, but they could if they wanted to). For the ECTA, there is a vendor which can supply you with Gas, but the tank is not sealed like it is at Bonneville. A lot of people purchase VP at ECTA because of the convenience factor.
