I'm going to throw out another theory - the gas.
My cruiser generally gets about 14 mpg. I get to around 230/240 before the low fuel light comes on. This is with 285 AT tires and low elevation. This also is my daily driving, not highway trips, so 25 mile jaunts for the most part on secondary roads. (Uncorrected mileage and well maintained vehicle)
For the last 3 or 4 tankfuls, I've been getting around 260+ before I get near the low fuel light. Exact same driving patterns. This last tankful (different gas station) is early, but looks like it looks more like the old mileage.
I would have thought it was a "winter gas" thing, but it is obviously the fall and, as far as I know, we use the same gas year around in VA. So now I'm wondering if it is ethanol content or something similar (I go to different gas stations). But I can definitively say I saw a significant change in mileage over several tankfuls with no change in driving patterns or state of tune.
