Paul,

One of the continual complaints about the rotary from
non-enthusiasts is that the fuel burn is "so much worse" than
piston engines. I found an interesting refutation in the May
issue of Flying magazine page 74 while reading a review of the turbo
Saratoga. Richard Collins writes that the 300 HP Lycoming TIO-540
motor has a BSFC of .65 in full power climb! Well, my my! Maybe
the difference is in leaning the mixture after all! And we don't
have valves to burn.

For your amusement.
