A problem for certificated aircraft flyers now is that most mogas now
contains 10% ethanol. In Oregon it was previously only in the winter in
metro areas, but now it's the whole state year round. Mogas STC flyers
cannot use mogas with ethanol. On my experimental with automotive engine
this is not a problem.
Probably about 1/3 of the approx. 6000 gallons of mogas that has been
burned in my aircraft has contained 10% ethanol, with no ill effects.

Perry/Paul--we worked through the Oregon Department of Aviation to get the
law changed since last year's ethanol mandate. As a result, the new
amended law in Oregon law allows non-ethanol auto fuel to be provided for
aircraft in Oregon. The legislation doing this was amended House Bill
1079
in early 2008. I believe the first Oregon airport field to provide that
at
the pump subsequent to the law change is Lebanon airport. Dan Clem, the
new
Department Director at the ODA did a great job on this. It now allows
auto
fuel distributors to supply the unblended (non-ethanol) for aircraft.

Steve,
I am polishing a white-paper on so-called "alternative" GA fuels and the
engines that can use them. The presence of ethanol in mogas in the US is
a major issue for engines certified to use mogas. My point is that
ethanol
is blended into gasoline at the level of regional distribution depots,
i.e.
that it is possible for a FBO to buy a truck load of UNBLENDED mogas. If I
read your message correctly, that is what's happening in Oregon. Can you
please confirm that it is indeed the case.
Thank you,
Francois
Francois--that is exactly the case now in Oregon regarding automotive fuel
sold for aircraft under the new law change . The distributor/station is now
allowed an exception...allowing them to supply the UNBLENDED. The
distribution challenge now remains. Pilots will need to communicate in
sufficient numbers to FBO's, service stations and distributors regarding the
market out there for the product to convince them it is worth doing this. A
great reference with more background is Dan Clem, Oregon Department of
Aviation Director. Dan's telephone number is 503-378-2340. In some
instances, such as in Independence, it is my understanding that individual
gas stations are providing it to pilots who bring down containers.
Perry--we worked out an agreement for the Oregon ODA to assume operation of
the Mulino airport and it appears Dan has a commitment from the same
distributor who supplies Lebanon with unblended auto fuel for him to also
provide the unblended mogas for a new self-serve at Molino soon. Not
official yet, but we should know soon. Hopefully soon on those Saturday
breakfast runs to Mulino you should be able to fill up for that rotary if we
can close the deal.
