That sounds like pretty normal city mpg's to me, thats about what i get even after tune ups, i only really see difference after the tune ups with highway mpg's

Why stock plugs still? That's cheap insurance. Change mine every oil change

Hmmmm. I would start with some new plugs. Unless modded, I'd say stick with the stocker AC Delcos... But others will comment and probs have better advise on that....

Have you checked....
1. Any small vacuum leaks?
2. Clean throttle body?
3. Clean MAF sensor?
4. Tire pressures?
5. Make sure your car has good allignment/ no dragging brakes and such?

And is this a reoccurring problem? As in this has happened multiple tanks in a row? I posted recently about my shitty mpgs but after filling up again I found my MPGs to be back to normal. back to low mid 20's for city and mid 30's on the highway again.

You would have to jack up the car to check the brakes. I would recommend cleaning and lubing your caliper slides. Little bastards like to get stuck up every now and then. Also, check out your suspension components, and invest in a quality alignment.

Also get to know a good tech and thoroughly look over your car with a scan tool. Clean your MAF, check your air filter, what kind of tires do you have, drain and fill your gearbox with synthetic lube, etc. Maybe even get an injector service done.

I know you're joking, but I don't get people who say that seriously when their car just has maintenance to be done. $1000 in parts and labor is a lot less than $400/mo for a new car.
