I'be gotten about 21 MPG from the day I rolled the car, and it now has 107K and I have yet to change the 02 sensor.

Am I just lucky, or what?

Got ya beat 260K on the Trans Sport and the original 02. I still average about 22-25 MPG in the city and now that I got the rack replaced I'm getting the best MPG ever.

I get about 18 city and have peaked at 32 hwy.
the wife gets 14 city, but then she goes the most indirect routes, hits every stop sign or light made.

I drive about 50/50 on my car right now mainly because it is now spring and mi has put all the road I drive under construction, My car gets about 24mpg when drive it to texas it got 26 mpg. Before I gave my car tune up(o2,spark plugs,fuel filter change) my car got 5 mpg 8 mpg. The O2 was the 1st I replaced a brought it up to 20 mpg and then did the other stuff a later and brought to what is today.
