I've been getting crappy mileage from day one. Bought it in Georgia & drove down to Florida. The first tank of gas 33 mph. Next tank it dropped to 27, now 23 mpg every day in mixed driving.
I visited the hills of Tennessee in October for some HARD driving & my mileage jumped to an average of 28 mpg. Over 32 mpg on the first leg on the way back.
I think it has more to do with the gas than anything else. I may change my O2s some day - just to see if there's a difference, but for now I'll just pay N pay N pay for the extra fuel.
