[f-AA] Auto-gas STC

[Larry Waggoner]

I have been involved in the petroleum business for almost 50 yrs.  My
trucks, (oops I am retired and should have said my son's trucks) have
been transporting that stuff all that time. In MO; ethanol is added to 89
octane gas and the 10% ethanol that is added brings this 89 octane  (also
called mid-grade) to 91 octane.(Premium)  This requires a placard on the
pumps telling you there is 10% ethanol blend. The ethanol is not put in
at the big product  terminals.  You mov e your trucks to a different
location where ethanol is stored and load your 10% blend. (In our case
850 gallon of ethanol)

$30.00 is is charged for this so called "split". The feds give petroleum
distributors a break on taxes if they blend the ethanol.  So, the 87
octane gasoline is also blended because it makes it cheaper to purchase
the product with an ethanol blend. Here is the kicker.  You do not have
to placard your pumps if you are not increasing the octane for an
additional cost. The regular non lead gas, 87 oct., has been blended with
10% ethanol, but you do not have to notify the customer at the pumps. 
Only if you use it to increase octane to charge more for it.

Right now, they are charging more for ethanol in MO, so the distributors
are not blending ethanol with regular non-lead 87 octane. However this is
unusual and will not last for more than two or three days. Soon they will
have no choice. 

Tony was correct.  Very soon it will be mandated ALL gasolines will have
some type of  blend, so you might as well get used to using aviation
fuel. They are building those big "Stills" (alcohol plants) all over the
US. Mid grade gas is half non lead and half 91 premium.  Beware, ethanol
will still be added if the product makes the complete load a litle
cheaper.

Now you know why I have spent all those years flying and let my family
run the business. <G Larry

OK guys This question comes up a lot and we need a "handout" that can be
emailed to answer this question.    How about someone volunteering to put
together the combined knowledge of the group. Fly frequently, many times,
often, over and over again, and LOOK around, Regards,

  How common is the use of auto gas in a 7AC?
  Any pitfalls one needs to be aware or if using auto gas?
  I know not to use ethanol, but have heard some concerns about lesser
  amounts of alcohol being added to gas without having to be labeled.
  Would there b potential problems with that?
