Thanks all for the responses regarding the crappy mileage issue with
my van.

  I have ruled out tire pressure (I keep a constant eye on that),
tuning (A new rotor & distributor cap where put in less than 10k miles
ago. Timing was checked, plugs replaced, new air filter, etc. Idles
fine, too. ) and speed (I drove about the same speed on same trip).

Possible causes are ethanol and dragging brakes. As of July 3, 2007,
Governor Ted Kulongoski signed HB 2210, mandating that all gasoline
sold in Oregon contain 10% Ethanol. Since it takes 1.53 Gallons of
ethanol to equal the energy of 1 gallon of gasoline, that equates to
exactly 2/3 the mileage. So, that's about 1 MPG hit. My trip to Oregon
required I fill up 3 times with the ethanol blend. Apparently, CA does
not have much ethanol, but I did read that the 76 brand is ethanol
blended. I will have to pay more attention to the pump labeling to
avoid ethanol. MPG did not improve with CA gas.

I recently installed big brakes in front & adjusted the rears, so
there may be some dragging. I have not noticed any heat buildup after
being on the freeway for hours, so I doubt there's enough drag to
affect mileage. The drums and rotors were cool to the touch. But, when
I spin the wheels in front, I do hear the pads against the rotor. Is
that normal?
