What oil are people using in the Hirth F23 engine; carburetor and injection models?
Carburetor, 50:1 Castrol Power 1 Racing 2T aka Castrol TTS.
Had good experience with this in in my Rotax 582, and I like the smell of the exhaust!
80 to 1, some fuel injection guys are doing 90:1
Bluemax for both, you can order from Matt recpower.com
Thanks Jeffrey. What mixing ratio is recommended for both engine models?
