Another big advantage to 4-strokes is that they burn less fuel, and at $14 - $18 a gallon it adds up quick!

Is seems that Saitos tend to burn more than an OS does, but to give you an example, an OS 91 4-stroke will burn much less fuel than a 60 2-stroke. For me, once an airplane gets into the 60 2-stroke range, that's when I switch to 4-strokes.

With a 90 2-stroke, I sure wouldn't want your fuel bill!

You will recover the extra money spent for a 4-stroke in the first month of buying fuel
