Dean,
If you are in a gas class, you are using gas. In a fuel class you are free to use anything, correct?
Do they require that you use the vendor's gas at Loring?

Dan, for sure if you run in a fuel class, anything goes. In a Gas class, yes and no. A VP vendor will be on site in Loring with sealed pails of VP. For the great majority of entries, this will be the gas source. But, like the ECTA, you can bring your own GAS in a manufacturer's sealed container, and the fuel vendor can fill your tank and seal it. The ECTA vendor sells "Rocket Fuel" brand gas, I haven't had any issues with their 118 in my turbo, but some NA folks with specific tuneups (like Greg) would rather run their own gas.
The extra wrinkle with Loring is that Maine state laws prohibit MTBE, which is common in oxygenated gas. So to run certain VP gas, you'll need to bring it with you from out of state.
Just a few days away, everyone make their tribute to the weather Gods!
