| Subject: | Re: Fuel - Mogas |
I have run a few hundred hour burning 90 octane E-0 pump gas through our
Cherokee 140 with the Petersen STC. The engine and plugs prefer E-0 to
Avgas. Worrying about engine materials interaction with ethanol/mogas/pump
E-0 is only part of the equation as Kelly points out. The STC covers the
engine and also the airframe. Our Cherokee airframe and o320 have an STC
while other airframes with the same engine do not have the STC. The fuel
delivery system in the aircraft is as important as is the differing
performance they fuel may deliver (boiling point, power output, gph burn
rate, etc). Additionally the E-0 will sour faster than the 100LL. The
100LL is plentiful on cross country flights which is where the RV-10
shines. We dolly a 125 gallon E-0 fuel cart to the field for the Cherokee
which will rarely fly far enough way to warrant getting gas away from the
fuel cart. The savings are around $0.70 a gallon.
