question about MPG

hey guys , just curious what MPG you guys get ?

I get around 10 in city, and around 18-23 on highway
city mpg sucks in my opinion, I heard some people have like 15mpg in city
and if mine is too low any sugestions on how to improve it? I thought about changing plug wires, but i doubt thats the problem

thanx again
