Forgot where it was but Ive been getting around 17 to 19 mpg. Going to get an oil change soon but what else could I do to improve the mpg? Should I change my spark plugs?

That and check the fuel pump recall.

I've seen high mileage cars get a noticeable mpg increase from a professional fuel injector clean as well.

Should I clean my injectors before I do my oil change?

injectors have nothing to do with an oil change. personally I would just put injector cleaner through the gas tank for a couple tanks and that should clean them out.

Ya I think Im gonna do that since my car's at 120k so I want to clean the injectors. Plus since Im getting an oil change Im gonna replace the spark plugs since I think they are still the ones the car came with since new. Plus need to change my transmission fluid because I know thats never been changed. Hopefully that will make my car run like new and get some better mpg numbers.

OK, thks! Then definitely get the fuel system serviced...should be getting close to mid-20's in town/city driving. Something seems to be amiss...

A tune up will always help increase mpgs. I would replace the plugs, run fuel system cleaner (Sea Foam is the best), make sure the plugs are gapped right, make sure the tires are inflated to the proper psi (says on the driver door area, I think it's on the frame rail on the car itself towards the rear of the door, it should be white/yellow/black sticker).

Tires are suppose to be at 30 psi it says but every car I've owned it was 35 psi. Weird

I always ran about 28-32 psi on my SS unless I was going to be beating it pretty good. Then I'd run about 22psi on the track and about 24ish on the street.

A lot of people say Seafoam is BS and it doesnt do anything. Its just a smoke show because it has stuff in it that will smoke no matter what.
Used it on my gfs civic she used to have because it had a rough idle. 1/2 in oil, 1/2 in fuel tank, almost a full can into the intake. It smoked for a bit but the rough idle went away and throttle response seemed to be better.

Seafoam's a good fuel additive...run in both HD's and all my small engines, but not a fix for smoking motor. Might want to get that checked...could be valve guide seats, rings, head gasket, etc...

If you're seeing smoke = something worn through.
