sorry if I've expressed myself wrongly, but that wasn't the point of my question(s). Viper's got the point, though (I think).

So it seems that for the RAF, there are close to zero useful 'lean mixtures'. What about the Luftwaffe? Does anyone know or does anybody fly a lean mix at altitude; i.e. a non-forced one?

edit: Oh, @ze-jamz: When you were adjusting your mix to blue-ish exhaust flames, did that make your engine/plane shake or vibrate? Which plane did you fly anyways?
