Gas Mileage on a 94 GT.

The Fireman · 05-18-2001, 11:35 AM

I NEED someone to tell me what kind of gas mileage a 1994 GT with the 5.0 gets. I've never owned a Mustang before but there isn't a day goes by that I don't wish for one, and I FINALLY found a great deal on a 94 GT so I really need this info before I buy it and spend 30 bucks at the gas pump everytime I fill it up.

Well Fireman, I don't have a 94GT but I have a 95GT and they pretty much identical

.

I'm not sure where you are, but if you are talking about $30 a tank I would guess that you are in Canada as that is what mine takes. Assuming the car is stock and in good running order you get actually get pretty good mileage around town and great mileage on the highway.

I kept good track of my mileage, only I go by how many km's I get per tank or litres. Most of the time with city driving I get around 400 km per 45 litres (tank, I always fill up at 1/4 full). On the highway I have gotten as high as 600 km per tank! (that's running closer to empty). My car needs a tune up right now and just before I was only getting 300-350km on a tank.

The thing that screws everthing up is when you start to step on the gas. As soon as you do that, these cars (stock or modified) drink fuel a plenty!

Hope that helps. Sorry if you think in miles, you'll have to convert all that (I'm too lazy. It's 5:40 pm on a Friday on a long weekend and I'm still in the office

)

I have a 1990 5.0, but have a 1994 crate motor in it. It is somewhat modified and I get about 12 miles per gallon when I am strictly in town, but get as high as 29 on the hi way. Usually with a combo of driving I see about 19 mpg. Use the search engine on the site to find old topics on fuel mileage....we have covered this topic several times. If you pull up those topics, it will give you a good idea of what mileage everyone gets and what mods they have on their car. Good luck!

I have a 90lx and i get about 17mpg with 100% city driving. A 94-95 should be the same, or more likely, better, as i think that they went to the new igniction in 94.

I'm pretty sure the Fox bodies will get better fuel economy in town, just because they weigh a couple hundred pounds less.

My 87GT gets 19-21cty/27-29hwy.

I'd expect a 94GT in good tune to get about 17-19cty/27-29hwy. They have a better coefficient of drag than the Fox cars, so their hwy economy should be better. My hwy mpg is best at about 70-75mph with 2.73's.

Keeping your car in tune will make a big difference in the amount of fuel you use. Many times using a higher octane fuel will HURT your fuel economy. Lot's of gas with the super, and premium label's are blended with 10% ethanol. Ethanol blend will cost you 1+ mpg right there. Keeping your O2 sensors working well by replacing them at recommended schedules can really help your fuel economy too. I've routinely seen people pick up 3mpg by changing them when they are getting old. When they aren't functioning at all, you'll lose TONS of economy. Making some light mods like a K&N filter, and hiflow exhuast can give you another mpg or two, plus make your car sound and feel more powerful.

All in all, when it's tuned right, and not heavily into N/A performance mods, the Mustang does a lot better for fuel economy than what most people think.

Your right about the weight unit, but i'd think the new ignition of that year would have been good for something, maybe offset a little of that weight?

Unit 5302 · 05-20-2001, 03:25 PM

You're looking at 1mpg per 100lbs.

That's about 2mpg in weight. Now I run SD, and I shift at 3000rpms, I find that gives me the best economy.

I honestly don't know of a new ignition. Now the OBD II, found in the first Gen 4.6L maybe better with economy, but I don't have one, so I can't say.
