On average how many miles per gallon would you say your 2005 dodge neon gets?

what was the original problem? when was your car last tuned up? if the plugs, wires, cap and rotor are worn out, it won't help. what about the pcv valve, air filter and oil breather filter? are your tires properly inflated? and lastly, how do you drive? if you do quick takeoffs and stops, you will get crappy mileage no matter how the car is tuned. I can get 29mpg from my son's 2000 mirage, but he only gets 23mpg.

if its mostly highway driving you do then you should def be close to 30 or better. def would have the car looked over, could be a multitude of things. tune up time

I drive it like i should, only times I "gun it" is if i need to, to avoid being hit. I rarely even pass cars, and often put on cruise control to maintain a set speed. It was tuned a little less than a year ago, and i'm not so sure on filters. I check the tires regularly, I do feel like some plug wires may be in need of change, because when ever it is moist out I have trouble starting my car. It hasn't been a problem lately compared to when it was snowing, and snow was melting constantly.
