Only filled my 01' wagon about 5 times so far.
90% city driving: 23mpg
70% city driving: 22mpg
Replaced fuel filter & spark plugs as well as plugging 2 leaky tires so I could inflate them to 34psi
90% highway driving: 31mpg
100% highway driving: 33.7mpg
50% city/highway: 25.8mpg
I'm not impressed or disappointed with the mpg's I'm getting. 25 is what I expected from a crappy Zetec + heavier wagon anyways.
I'm positive my sputtering fuel pump is decreasing my mpg by 1-2..gonna take it to the ford dealer soon to get that addressed. Plus I know my alignment is off in the rear which could be affecting economy a bit. I should be able to bump the econ to 27 average if I work at it, but for now I don't feel like spending the money.
