I have an 89 LX sedan auto tranny and I get about 305 to 320 miles off a full tank. I don't know how accurate my gas guage is and I don't have a low fuel light so I fill up when it gets really low.

I'm wondering what the typical range is for an automatic civic.
I dug up some old logs showing up to 400miles off a full tank when my dad drove the car.

It might also be that he drove it really slow, but my car is so slow that if I don't if I don't press the gas a bit (not flooring) people are almost ready to start honking. It's not hesitation slow either, it's D15 92hp slow. It's decent, and it's been relatively reliable, but in heavier traffic where I need accelleration I almost have to floor it.

I just changed the spark plugs as it needed new ones. Will this help the mpg any?

 

if your old spark plugs were crap then yes.

 

what is the average range you get of your car?

 

If you are worried about milage, get a tune-up. How old are the wires? Are they clean and shiny on the contacts? How old is the O2 sensor? When was the last time the timing was checked or the valves adjusted? Check out the little things like that, and your milage may increase significantly. Oh, and yes, new plugs will help milage.

 

Thanks. It needs a tune up. I've done the belts part of a tune up, but the valves need adjusting and might need new wires.
