You gotta watch that little floating bar on the bottom, the one that shows you instantaneous MPG, ---- you should even see it touch 30 once in awhilec...... pay attention to it... Whenever it's below 10, you know you are doing something wrong..... LOL
I averaged over 20 MPG, for a 1500 mile drive home, when it was brand new. Best tank was around 28, believe it or not (first 300 miles).....

I'm like OldJeep's averages - about 15-17MPG.

And that was calculated, individual tankfulls, and total for the whole trip. Gallons of gas bought/miles travelled. Every tankful was filled to the top of the filler neck, until it wouldn't take any more.
My worst mileage, was when my wife (Parnelli) was driving. She does have a heavy foot. Yes, I call her that to her face - she just smiles!
One thing that is as important as anything - is how you drive when you have a choice! i.e., accellerating slowly when going downhill, and slowly decellerating when going uphill. And, really easing into the throttle, when you start to get going, or when accellerating in town. Keep that raw egg between your foot and the gas pedal, and try to stay away from the brake.
If you really behave, and get to drive a lot of highway miles, you can get really respectable mileage. Travel between 45-60MPH nets the best, and 65MPH is still acceptable. Over that, and the MPG goes south in a hurry.
Around town (I live in the Chicago super boonies) I normally get 13-15, rarely a 16.

Women are the worst enemy of fuel economy. My ex-wife used to get about 12-13 mpg combo driving her '02 Grand Cherokee Sport 4x4, with a 4.0 I6 engine. When I used the thing, I would get 17-18 and could even match her MPG the few times I used it instead of my truck to pull my 3000# bass boat to and from tournaments.
I drove 99.9% of the time we went anywhere together, from the time we first started dating till the day we got divorced, 15 years later. So I never really saw her driving habits. Had to change the brakes on that '02 one day, squeeling and pads were beyond the wear indicators - WITH 21k miles on it!!! Now I had a pretty good idea about the gas mileage. Went out a few times and made an excuse or two for her to drive (contacts dry/headache type excuses so she wouldn't think I just wanted to spy on her driving).
This woman didn't know ANYTHING other than FULL GAS/FULL BRAKE!!! There was NO coasting. Gas pedal right up to she took her foot off it to hit the brake at a stop sign or traffic light! That IS NOT the way to squeeze out fuel economy, LOL...

No discernable difference in mileage, other than a nasty premium for the 91.

I have tried different grades, noting no difference in mileage, but find that vehicles that are designed for lower octane fuels, seem to run better on them, than the higher octanes. My wife's Caddy, designed for premium, always does better on regular - don't know why. I find no difference in my Hemi running regular or mid range. My Goldwing always runs better on the lowest octane I can find.
Another point of information - vehicles start faster on regular, due to the lower ignition point of the lower octane fuel - good to know in the wintertime.

Pre-tuner days I never saw any mileage difference between 89 & 93 octane fuel, have never put 87 in it nor would I ever in a vehicle with a compression ratio over 9:1.
I have always found there to be a significant boost in fuel economy when purchasing 100% gas and not E10. Usually about 2 mpg whether with the stock tune and using 89 octane or with the tuner and running only 93 octane in performance mode.
Ethanol just sucks a$$...

Are there any gas stations that do not put ethanol in their gas? I have been looking for a year or so for my Demon and Coronet. I may have to put Blue Torch 120 octane leaded racing fuel in them, but it is $7.00 + a gallon,
