Maybe a fuelish question?
Just wondering if you get better mileage towing with premium gas that does not have alcohol in it over regular gas with alcohol?

Okay I have to say, there is not various levels of octane because the factory wanted to change the timing so the petroleum companies can produce a more costly fuel.
The octane ratings are based on engine design primarily around the compression ratio. Though it is true you can step up to the next level and get some improvement but also in today's engines you have to let the computer learn the different gas. Best is to stay with one type and don't change. It isn't like treating yourself to a steak over hamburger. You do not do your engine any good by giving it a higher octane.
I do do what the OP originally asked and put my old gas from the yard working machines every 3 - 6 months in the tank but I do not expect better mileage.
