For instance... I run my PA-28-180 at 65% in cruise, leaned to peak
EGT, and
run 120mph IAS at 8-8.5gph. For bopping around the local area (in no
particular
hurry), about 45% power leaned until it wheezes will give me 100mph
IAS at about
5.5-6gph. CHT's stay at 375 or below... life is good.


That's pretty good! Over the last 15 or so flight hours, I've been
doing similar testing on my Cherokee 180 and I haven't been able to
break the 6 gph barrier. At 2100 rpm @ 7,500 ft and 105 mph I averaged
6.1 gph. At lower power settings the higher angle of attack was
negatively affect my CHT.
