1) TUNE UP!!!!

2) Use a light foot.....ALWAYS,

3) Inflate your tires to between 37-39psi.

4) Lose weight or if weight has been lost, keep really heavy people out of your car.

This right here might be too much, as head increase pressure will go up as well.

I keep mine at around 32psi.

And i get around 23-24 mpgs, so don't expect wonders.

open you drivers door and read what the manufacturer says to fill your tires up with the correct PSI.

the 37-39 PSI is for Auto-X, etc.

I was just letting him know what worked best for me as far as gas mileage. Been doing this for almost 11 years now with no ill effects or extra wear on tires. The manufacturers recommendation should be followed but it never got me the best gas mileage. I just happen to have a 2.2 '97. .2 cents...

"Keep RPMs below 4000 RPM unless in a case of emergency."

Yep, that said.

Actually, it is just recommended pressure for the inside of your doors. You can inflate them up to the max listed on the sidewall of the tire and be fine. You can do the research to find out how this isn't harmful if you want.

This site may help you out a bit too: http://www.cleanmpg.com/cmps_index.php

I tend to get 28-31mp city in my car incorporating a few techniques from this website.

24 MPG isn't too bad (don't forget the colder weather means less MPG). I get anywhere between 26-30 MPG depending on where I go. I have a very light foot.

As stated before check your tires, get a tune up if you are due, and drive like a grandmother.

i just read some articles on that site. the mpgs they're getting is amazing

i gotta try some techniques. of course there's some stuff i can't avoid (like driving w/o awd or avoiding hills), but it was interesting reading how inflating your tires up the the max psi on the tire sidewall is perfectly fine. i want my car to get 30mpg

the information stated on that website about inflating your tires to max pressure is incorrect. while it is still safe for the tire's integrity it will cause poor treadwear on most tires (not improve treadwear! and only very low profile tires can get away without any noticeable change in treadwear) and it will absolutely decrease grip levels. your tire will no longer be able to conform to the small contours/imperfections in the road surface like it could with a lower pressure. It wont be a night and day difference in terms of feel, but in an emergency braking, maneuvering and even acceleration may suffer. This has all been proven.
If inflating your tires to max pressure was an easy, no loss way to gain MPG then the auto manufacturers would design their suspension to ride comfortably on 65 psi.

Their is no doubt that running at a higher tire inflation pressure will decrease rolling resistance (friction) and increase efficiency, however.

tire friction is also a VERY small part in what your engine has to overcome to accelerate, or even stay at the same speed. Wind resistance is the big one. stay under 60-65 if you can help it.

oh, and with 148K on the car, tune up. when was the last time air filter was checked? how about O2 sensor?

It isn't THAT hard, but you will have to work for it, somewhat.

Keep in mind I was getting about 24-26 city when I first got my car. I tend to have a very light foot.

I also didn't exactly inflate my tires all the way up to the max, but about 5 psi below max.

im getting 26+ city with a moderate foot, running 36psi front 34psi rear w/ a tune to go along with bolt ons. which is about 1.5mpg better than I was experiencing with the stock setup/stock tune. I dont do much freeway driving, and when i do, i usually have two bikes on a yakima roof rack, so my mileage is pretty dismal.
