Scott, Walter, = anyone,

hypothetical scenario with = estimated=20 values:

Flying at 15000' going east, WOT, = 2400 RPM,=20 14.5-15.5 GPH, 220 to 230 kts ground speed with 30 kt tailwind; EGT @ = 1260, CHT=20 @330. Fuel computer says 900 nm of gas left, 1000 nm to go, takes = about=20 1hr to land, fuel, and get back up in the air.

To make the trip without landing, = lower RPM=20 to 2100, begin aggressive leaning, engine sputters @ 9 GPH, enrich to 10 = GPH,=20 EGT's go up to 1300, CHT's to 350, GS ~ 190-195 kts with same tailwind. = Now fuel=20 computer says 1200 nm left, 1000 to go, have fuel margin and do not have = to=20 land.

Am I hurting my engine with the = aggressive=20 leaning??
