What is your gas mileage like?

the 38 mpg number was with my 2.73 diff on a long flat road trip with my green 96 m44

city wasnt near that high but when i got on the highway it was smooooth sailing!

Finally filled up my car for the first time (took me 1.5 months to put 358 miles on it). Gas mileage worked out to 28.925mpg. Was a good mix of city and highway driving, and there was quite a bit of spirited driving in there.

Now my question is how big are our tanks? I filled up shortly after it had dipped into the red and it took a little more than 12.3 gallons, so I'm guessing 14-15 gallons, and if I had run it dry 400 tank miles would have been possible. Am I close?

OBC has been consistantly @ 34MPG. 40mile one way drive to work on Back-roads/highway mix. 93 octane only. I replaced both of my O2 sensors and think that helped a little bit. (100,500 miles on car)
I'd prefer a Top Tier gas like Shell but they are $$ where I live = $3.99/gallon vs. $3.82 for Hess Premium.

Those EPA numbers seem really pessimistic. I always get at least 31.5 MPG via the OBC on the highway with cruise control and as high as 35.X. Accelerating like a grandma in the city nets about 25. 96 with 161k.

i now get about 24 in the city mostly

I reset my OBC after I got my car, I drive a little over half my commute highway. I also enjoy some very spirited driving often.

the OBC says I average 30.4mpg using 89 octane, in my 97 M44 with 80,000miles.

Just filled up this morning, calculated out to be 28.4 mpg. This was all city and suburb type driving, about 3-5 mile trips and lots of cold starts.

Car also just hit 122551 miles.. I took a picture of it, but it is on my phone and I have yet to learn how to get it off of the phone (first phone I ever had with a camera)

I want to add... last week I drove down to DC from Atlantic City. Keeping a steady 71mph, I averaged 32.2 mpg according to the OBC.

But to add insult to injury, that same trip taken in my "new" saab 900 turbo netted 34.9 mpg at the same speed.

Judging by my last fill up, our tanks are probably around 14.3 gallons.

[Bobbak]

14 gallon tank with 91 octane 450 miles so thats about 32 mpg

i got an m42

[zboot]

Official specs list it at 13.7gal but I've put in around 14.2gal one day when the car was a bit thirsty.

I've taken mine to kansas city and back. About 450 miles round trip and at 80-85 mph the whole way i got 30.6 mpg. I thought that was pretty good concidering my 5 speed was at 4 grand or so the whole way. Thats why i would like to find a better gear in the diff. Any ideas guys. And in town and driving all over(usually fast) about 26mpg. Yeah i run 92 octane to i get better mileage

Filled her up for the second time and ended up with 29.8 MPG. It was mostly highway at higher speeds (over 70), with a couple spirited runs. Was on 89 Shell in my '97 M44, 140k

[Borg561]

Second tank verdict is in (yup, barely a week) and it averaged 31.85mpg on 89 octane. Technically it was city driving (to and from work), but in reality, about 80% of that was highway/interstate driving. My needle was about halfway through the redzone so I'm guessing the "Get gas now" feature (illuminating that red section) comes on with 1-1.5 gallons left.

It's nice knowing our cars have a fairly accurate gas gauge too. In my previous two cars the gauge was terrible. In my Cavalier I could usually get 200 miles on the first "half tank" but only 100 miles or so on the second "half tank." Drove to Chicago one summer and filled up about halfway there, with just over a half tank of gas left supposedly. Yet it took a hair over 10 gallons of gas (on a 15.2 gallon tank). At least when the needle got to around E I knew about how much it was going to take.

My Mirage on the other hand I never knew how much it would take. It supposedly had a 13.5 gallon tank (or so, I know it was 13.something). I would always fill up right after it dipped below a quarter of a tank left. The amounts it took ranged from 6.7 gallons to 9.4 gallons.

That almost exactly what I get running 89 Amoco or Shell. I have to make two 240 mile round trips every other weekend.
