????? No wonder you got fouled plugs. You should be around 13 gph at
23 squared for a 230 hp engine.


I'd strongly agree with this. I used to fly an S-35 Bonanza with an
IO-520, and I'd get about 13 gph in cruise (at 160 ktas at 8000'). I'd
expect Jay's plane not to burn more than this.

Which also explains why Jay can immediately tell if he is running mogas
or 100LL apparently. I can never tell. It never makes any difference
whatsoever.
