100 miles/tank ?

[eightyeight]

So I was able to pick up my 88 just a couple days ago. Judging by how much gas I've used so far, it looks like I'm goign to get about 100 miles to the tank. Even for a 5.0 that seems a bit low. Is there any problems I should be looking for or is this about right for an '88 5.0 ?

I get just over 100 miles before my fuel low light comes on. That's between 9 to 10 gallons when I fill it up so I get between 10 and 11 miles per gallon on average during strictly in-town driving.

On the highway, I get between 20 and 25 MPG depending on how much I use the cruise control.



Edit: I should also note that this is on a blower car.

Yeah- when I use the a/c all week I get about 110-150 or less

 

[88 Fox GT]

I get 230-250 miles to the tank on mine if I take it fairly easy on it.

That's only like 11 gallons too, because that's all it will hold.

ACtually the tank is a 15 gallons i would almost bet the gauge is off. When mine is on E i can put in 9 gallons so there is six gallons of play

I have an 88 stang tank in my car and I get 290-300 miles to a tank. When my autometer gauge says empty I normally have about 2 or 3 gallons left.

I get about 200 miles per tank on mine with a little spirited onramp runs. Something definately doesn't sound right.

Running mine hard the whole tank I get about 250-275. I dont know what it gets when your taking it easy on it, I dont think I can drive that car without the pedal down.

I don't see how you guys get that good of gas mileage unless it's a lot of highway mileage. My car doesn't see much highway time, but it's mostly stock and a tuneup a few months ago. Right now it's averaging 15ish being driven hard.

Im getting on average 22-23 mpg with a combo of city and highway driving.

I'm getting great mileage b/c my tranny is broken, ha...and its my only car....my legs are getting tired

Welcome to the boards!

In reading your first post, I'd simply go fill up and actually calculate the milage. The stock gauge is too inaccurate to interpolate.

I would run codes.

Good luck.

My 03 Cobra gets better gas mileage than that. I would check everything related to the fuel system, including pressure.

dont feel bad my 557 inch got around 6mpg

I am getting about 24 mpg out of my 88 GT. I fill the tank, use most of it before I fuel up again then check my gas milage. I thing most of the time I get between 225 and 275 miles out of a tank depending on how I drive. Cool user name by the way.

I've got as much as 330 miles on a tank of gas, combo city and highway. I average about 260-300.

If I drive sensibly I average about 22-23mpg in my GT.

Hmm, mine must be off then. Both Fox bodies I've owned have only held 11-12 gallons max when the needle was on E and the gas light was on.

 

[iwashmycar]

Mine gets about 300 to the tank with the 15.9 gallon tank. When i did a lot of highway driving the part week i got above 350 miles to the tank, with the A/C on lol

 

[ninety15.0]

On the highway i get about 225 miles out of a "tank" and at that point the gauge is at about 1/4 tank. When i go to fill it up i can only get about 9 gallons into it. Thats 25mpg....averaging about 75-80 with 3.73's. Around town is a different story i get about 14mpg. How hard are you driving it. Do u have a vac gauge!!!??? best thing i ever purchased...it really lets you know what works best for your car. And generally short shifting a 5.0 is the worst thing to get good milage! good luck

Before the rebuild and with the 2.73's, I could get up 350 miles on a tank on the highway cruising at 80. Now its more like 230 miles with 1.5 gallons remaining. The lowest MPG that I have had so far was 16 for combined city/hwy driving.

If your only getting 100 miles to a tank, your either driving really hard, highly modified, or there is something wrong.
