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. ------------------------------------------------------------------------------------- Other Matronics Email List Services ------------------------------------------------------------------------------------- Post A New Message rv10-list@matronics.com UN/SUBSCRIBE http://www.matronics.com/subscription List FAQ http://www.matronics.com/FAQ/RV10-List.htm Web Forum Interface To Lists http://forums.matronics.com Matronics List Wiki http://wiki.matronics.com Full Archive Search Engine http://www.matronics.com/search 7-Day List Browse http://www.matronics.com/browse/rv10-list Browse Digests http://www.matronics.com/digest/rv10-list Browse Other Lists http://www.matronics.com/browse Live Online Chat! http://www.matronics.com/chat Archive Downloading http://www.matronics.com/archives Photo Share http://www.matronics.com/photoshare Other Email Lists http://www.matronics.com/emaillists Contributions http://www.matronics.com/contribution ------------------------------------------------------------------------------------- These Email List Services are sponsored solely by Matronics and through the generous Contributions of its members.
