What are you getting around town in your Civic? What's considered
"normal" for gas mileage? My son says he's getting around 17-18 mpg with
a/c use and 17's mounted as wheels, and a fart bomb exhaust ('99 Civic
EX coupe). As we didn't mount the wheels, I am guessing the speedo gear
wasn't changed when the new wheel and tire size were mounted, so the
actual mileage may be off from that, as well.

Also, can you get a true reading of MPG when you fill up at half a tank?
The reason I ask is it always seems like the first half of the tank is
used more quickly than the second half? Myth, or true?
TIA.
