If there was no difference in the power/mileage, why would there even be two mixes. That was my thinking.
Being an (ex) turbo car guy I used to believe that oil in gas kills the octane, big time - and it IS true for 4-stroke engines, especially with regular (crankcase) motor oil. But 2-stroke engines and 2-stroke oil, not so much. Some of the oil does combust, but a good oil drops out of the vapor mix very near the top of the compression stroke, to seal and lubricate.

I think the two given ratios are a bit of a red herring - I can see some extra lube for break in, but...........
