When we got home we checked the fuel meters on the mogas and 100 LL fuel storage systems using a 5 gallon fuel container and made sure both fuel delivery meters measured the same. After the flight I required 18.7 gal. -0 .7 for the go-around = 18.0 gal. of mogas. My neighbor's aircraft took 19.0 gallons of 100 LL. My fuel costs $2.00/gal or $36.00 His fuel costs $3.50/gal or $65.00. The Mazda Technical Papers on the Renesis indicate a significant improvement in fuel efficiency over earlier RX-7 versions.. I believe this flight proves it - the Renesis beat a Lycoming with fuel efficient "E" mags.
