27/09- AVGAS vs MOGAS
run an IO540 on MOGAS and you will find they produce far far less power for the same amount of fuel.
I assume you have done this in flight or on a very well instrumented dyno and observed or recorded the results. So what did those tests reveal?
I am really keen to know as the laws of physics I work with could be wrong.
And yes there are notable issues with various grades of mogas, but lets look at the power issue first.
