gas mileage

i have a 94 sentra and it only gets about 22mpg. its great on the highway but shouldnt it be getting more in the city, or do older cars just do worse in terms of mpg?

Depends on how you drive and what kinda shape your car's in. 22 isn't THAT bad, but it sure could be better. Make sure your tires are inflated and aligned properly, your air filter and fuel filters are clean, you have good NGK spark plugs, and your PCV valve and O2 sensor are working.

I have to disagree, even when I really beat on my car for a tank of gas, just to see how low of fuel mileage I could get, I still got 25, and I normally pull in 35-40 with a mix of city/highway. But check the things he mentioned, though I would just do a complete tune-up if it has been more than 2 years since the last one. And also check to make sure your cat isn't clogged, if it is it can cause your car to run rich.

Yeah, I guess it could be MUCH better.
