I can't burn 100LL, it will foul my leading spark plugs after only 4 hours. That is because my engine runs rich-best power all the time. Of course running rich results in a higher fuel burn too. These days I'm doing about 160 knots on 8.8gph, or 184 mph @ 21 mpg. Burning mogas all the time, my leading spark plugs still only last about 50 to 60 hours. Trailings always look better. My 1988 RX-7 with exactly the same engine gets about 18.5 mpg combined city/hwy driving, probably low 20s if it was continuous freeway. If I had lean control I would expect results more like Ed Anderson with regard to 100LL and plug fouling. I would like to see some fliers express fuel usage in mpg, an easy way to compare efficiencies. For example, Tracy and Ed leaning might see 25 to 30 mpg? --0-331053478-1148315583=:55739 Content-Type: text/html; charset=iso-8859-1 Content-Transfer-Encoding: 8bit
