27 mpg. I wish.
My completely stock 2003 auto P5 gets 21-23 mpg in 95% city driving, almost all of which is just the daily trip 7 miles each way between work and home.
The car managed to eke out 28 mpg once on a trip that was 95% highway driving.
The wife's Subaru Legacy wagon weighs 1000 pounds more and gets virtually identical mileage. My P5's city mileage is just pathetic for such a small car. Yes, I've changed the plugs, filters, tires are correctly inflated, alignment is correct, it has been lubed, and no evidence of dragging brakes.
30.12 Mpg
I always get a consistent 25 MPG on my stock 2002 5 spd (75/25 city/highway), but I tend to rev pretty high. Anyway, I decided to take it easy for a tankful, and check it out...MPG increased by 20 percent!!! from 25 to 30. I upshifted below 3000, kept highway speed at about 66 with cruise control and just generally stayed out of the races. Couldn't believe the difference.
So let's do the math...at 12,000 miles per year, my old driving habits would require 480 gallons of gas. The 20% improvement in MPG would require only 400 gallons, a difference of 80 gallons. Multiply that by, say $2.35/gallon, that's a savings of $188/year, plus a lot less wear and tear on the brakes, tires, motor etc. I'm convinced.

The car gets significantly worse milage during the first 2/3s of a tank because you are lugging around all that gas.
The best way to track your milage is to run down to empty (when the light comes on) and fill up. Do this several times and keep track of your milage and how many gallons you put in. Add the total miles from several tanks of gas and divide by the total gallons purchased and you will get a pretty good estimate of your milage.

I call BS.
1 gallon of gasoline is around 6 lbs. A full tank of gas is 14.5 gallons, or 87 pounds. The car weighs about 2700 pounds and the driver another 150-200, so round it to 2900. The full tank of gas is only 3% of the total weight of the vehicle. The first half of this tank is <1.5% of the total weight. That's not a very big change. Probably over 10 or 20 thousand miles you could measure the difference this causes in mpg, but to call it "significant" is a stretch.
i've owned my P5 for a week now, and since changing out the plugs and using the fuel system cleaner, im getting about 28 highway and 24 city.
keep in mind that the more tread u have on the ground, the more friction. i saw this in my first car when i went from 195's to 215's.

I mentioned that in another thread and someone called BS on me. I suggested getting a pair of 185 or 175 tires if you were concerned about mileage. After all, that's what you see on the econoboxes. I doubt the Toyota Prius would get 40+ MPG with 225s on!
pfive, you may want to check the air filter while you're at it.

don't worry, y'all, you too can achieve 37 mpg!
just follow these simple steps:
1.) skip-shift 1-3-5, shifting at 2000rpm
2.) drive at a constant 61 mph
3.) do not use the brakes, ever! (if there is an obstacle in your way, like other traffic, swerve to avoid it - use medians if necessary)
4.) start at the top of a mountain and drive downhill
5.) pay an 18-wheeler to drive 61 mph in front of you so you can draft off of him
6.) hook a chain to the 18-wheeler in front of you and throw it in neutral
(drive)

If less pressure meant better mileage one could emulate high elevation by restricting air flow through the intake, which seems a bit counter intuitive. Sea level is about 14.7 psi and Denver is about 12.2 psi. Are you saying that if the intake was modified to restrict air flow into the motor by 20% at sea level the MPG would go up? Or is your point that there's less drag with less air pressure?

7.) drive up into the cargo area of the 18-wheeler and shut off the motor. Infinite MPG!

So lets talk about which mods and driving habbits actually increase your gas millage to 30-37mpg!? I only get 28 hwy/city on my 5spd and I dont even beat on my car (AT ALL), and usually shift at 2/2.5/3k. So idk what I'm doing wrong... I only have an AEM CAI, and my other mods listed below that prolly wouldn't make a difference. I use regular gas. Gino, help me achieve better gas millage! Cuz this $3/gallon s*** is killing me!
