Have always heard the 'midrange' fuel is the low- and high-test blended (that's
why it is usually 89-octane and the low
is 87 and premium is 91). If the midrange is the only one labeled as
containing ethanol I'd be very suspicious; the
station would need three tanks instead of two, the trucks would need 3
sections, etc. (all the gas trucks I've seen
have two trailers and two outlets).
