There is no real reason that FBO's can not get un-tainted
gasoline. The alcohols are added in when the truck is filled.
The difficulties are procedural not strategic...

Yes and no. Most trucks have residual when they return to the farm to
refill. Since most FBOs can't take the entire trailer, they will pay a
premium to the trucking firm for a dedicated partial load. That markup is
more than a few cents (more like 10 to 50 cents) per gallon, and then you'll
still get a small mix of residual.

The FBO is also not taking a trailer (or seven) a week, so every run is a
special. That means the trucking co will fit the FBO in with no guarantees.
So the FBO will need to schedule early (so as not to run out) and therefore
will take even a smaller load. Sometimes the load is so small the FBO will
have to take a mini, making the FBO pay for gas not taken.

Also, many of the Quicky Marts make more profits from the food and coffee,
than from the gas pumped. The FBO will not sell at such small margins, so
all said and done the Mogas will likely be a dollar to 1.50 higher than the
Quicky Mart. Now add in what Kyle B mentioned about the Mogas cutting into
the FBOs Avgas sales and it's a loser all around (for the FBO).

Damn those pesky details!
