I'm confuesed about what the cetane booster is doing as well. I don't think it changes the auto-ignition temp and it almost seems like it would make detination worse. But I have to say it seems like it helps.

I flew again today for about an hour on my Black Brew 4 parts to 1 part Davis Plane. I works well once the engine is warmed up.


I'm also wondering when we mix fuels with different auto ignition temps whether we get an average or we get different parts of the fuel lighting off at different times. If it is the latter it will allow us to time the layers of the combustion event to best suit our needs.

20% oil really seems like more than nessasary with pump diesel. I bet I could go lower but I really don't know how to tell when to stop so - maybe I will leave it alone.

Treven.
