FAA.gov doesn't list an engine type; just reciprocating.

Hey guys, yes, the power plant is an early version Eggenfellener H6 3L engine with stock Subaru ECU. I typically plan on 155 knots at 2200 RPM and about 10 gals per hour at 7-8k altitude. I burn 93 octane auto gas with ethanol, so fuel costs are still pretty low with the high burn rate. I have not tried to optimize\lean the fuel burn as have seen many other Subaru's not fared that well in this endeavor and I know my knowledge limits. I think there is some work I good do to reduce drag, but I never seem to get the energy to pull off the cowl and work on it, much easier to simply go fly.
I have been flying this plane for about 10 years and have just over 700 hours.
