I just called Nickey Petroleum in Placentia, the source of my Sunoco 110 (the
really good stuff). I get it straight from their pump 24/7 with the account I have with them. Ultimately I may have to complete a form with each invoice they send me stating which racing event I plan to use the fuel. No BFD.
For grins I might write down, "91 Freeway Flying Mile Contest, Saturday Night, 9pm".
Sorry to the OP.
