i could be wrong, but I do know that it cost Rozelle 40,000$ to setup their servo for E85. They got the contract with CSR in the city to supply fuel for their company flex cars.
Those other dodgy servo's may have not done this preperation like the United servo's do ? United also uses CSR sugar caine to make the ethanol which has been proven to be better then the other stuff available, not sure if its higher octane or not but I know the CSR stuff is the best stuff.
So yeah if united Rozelle are still selling then that would probly be why???
I should just go over there after work today and check this all out, once i downsize my turbo i will be going back to e85.
