Disregard the advice of BChi please.
If it is low smell, or a smell that is not objective you're after, Aspen is the only solution. It is a high grade alcylate fuel without the stink, and about the power of gasoline. It has 94 pump octane which is right for all engines I know, except super racers with 1:12 compression ratios.
Only drawback is, that with some carbs, it will not start again when hot!!!!???? Only after the engine has cooled down completely will it start again. No big deal, if you have to choose.
This is the only reason I switched to normal premium gas again after extensive tests. Starting procedure with "normal" gas is (much!) more dependable.
Advantage of Aspen is, that is has no summer or winter mix, and that it burns very clean without nearly the load of hazardous fumes that gas has.
Use 4-stroke fuel, and add the oil of your choice.
