My other concern is,with people using less of the premium gas,how fresh is it going to be now? It might sit in the tanks a lot longer now,and not be as good. The Sunoco station where I go to every morning for coffee,told me they use their premium fuel to blend their 89 octane gas rite at the station (a blending valve) so I wonder if that is what all stations do for their mid grade fuel?

I will try to think in terms of gas money $s instead of miles. Hope that will make me drive only when its worth it. But its depressing when you think like that..

A large number of stations do just that - saving a considerable amount of money on tankage. After all, whether it's done at the refinery, the loading port, or at your local gas retailer, each grade of gas is a blend of two hydrocarbons used as a reference: iso-octane (or more precisely: 2,2,4 trimethyl pentane), and heptane, also called n-heptane (chemical formulas C8H18 and C7H16). Depending on the blend, you get regular, mid, or premium fuel - plus an additive package.
