What Kind of Gas Milage are you getting

[Grims95SC]

I'm on the same tank of gas since last August when I blew my headgaskets! Not bad eh?

[brandonhgt]

UPDATE I replaced my o2 sensor and fuel filter and cleaned out my K&N. Mileage was back up to 26.7 driving 70/30 Highway/City, WOOOHOOO .

i have a 17.5 mile drive to work, and it's all on back roads...

speed limit is around 35-45 the whole way, so i just chug my way there...and enjoy my 22 MPG... i'd have to take a trip on the freeway to see what kind of highway mileage i'm getting.

I get ~260 mile to the tank with no OD, but I never let it get to the point where the fuel light comes on. This is after new fuel filter, pump, new O2's, fresh oil change & cleaned the air filter.
What size gas tank do the SC's have?

94-95's have an 18 gallon tank...i'm not sure about the 89-93's..the same i'd guess

I just made a weekend run of about 400 miles. 30 around town and the other 370 on interstate running 85 to 95 mph. I was happy to see 22mpg. I had no idea it was that economical at those speeds. It gets around 18mpg just around town. AOD and 3.23 gears. Catch you later, Bob.

Okay, I have seen two posts about 30+ mpg at 80-95mph. I think you need to redo the math. What process are you following to figure this mpg? It's not right.

I can't say I've gotten 30+ mpg, but I did see 28 mpg during a vacation trip early in my cars history. Now if I get 18 mpg on a long trip I'm very happy

My '93 has a 15gal tank.

92-97 OEM gas tanks are all the same size. I don't remember the exact size, but it's around 18 gallons. I believe the 89-91 gas tanks have a little bit more capacity.

Of course, none of this really matters for determining MPG since you should be using the number of gallons it took to fill up your tank, not the possible capacity.

We are officially tangent-bound....

Looks like my gauge may have been off a tad as I have never put more than 15.5 gallons in during a fillup with the gauge reading empty. Oh well, I'd rather it be that way than thinking I had an 18gal and in reality I had a 15 gal.

Also, true, when figuring gas mileage people need to fill the tank completely and then drive. Fill it up again completely and divide miles driven by gallons used to fill the second time.

In the theme of tangent-bound, I wouldn't trust any site's Thunderbird information that doesn't know the 89 is part of the same model run. Anyway, somebody with an 89-91 and a 92-97 owner's manual could state the fuel capactiy from the manual. I'll try to check my 92 manual when I get home from owrk, unless somebody posts the information before then.

I was thinking the same thing. Looking at the site, they do mention the restyle that occurred in '89, but for some reason they highlight just years '90-'97. [End of tangent.]

I have never checked it.. It gets to about 1/4 tank and I fill it up.

[rickbtbird]

Well I think the ruling is in, most people are getting under 22MPG
