Has anybody run an M10 engine on alcohol?. The government here in New Zealand has just released it's energy / emissions strategy and while it wasn't actually stated as such, I can see the writing on the wall. In the foreseeable future, if I want to go racing - I won't be filling up with petroleum.
Also locally, Motorsport New Zealand has started banning the use of Avgas for some classes , it will probably be banned outright in a year or so. They've also started mandating the use of alcohol blended fuels for some classes.
So the time for me to start researching the issue is now, long before the next engine rebuild.
