The 5.0 5-Speed Sport averages about 23 mpg regualr daily driving for me (moderate beating on it avg speed prob. 55, lots of country driving)

The 79 ranchero 5.0 same daily driving as above gets 16 mpg and on my last highway trip with an avg. spd of about 70 I got 20 mpg and it needs to be tuned. Not bad for a 28 year old carbed 3 speed.

My 93 5.0 HO got 32 MPG on my first trip to Cat Jam in 2004. Cruise set to 65, didn't touch a pedal for almost 200 miles.

Right now, gets 20 mpg highway, 13 local. I think I have a wiring issue, the car is running extremely rich (to the point where it fails emissions due to hydrocarbons), but it has no other issues, and will not throw a check engine light.

I seem to get about 22-23 city...

I was getting 26 highway (running the car at about 78 mph), I had wanted to see if it improved after I changed to royal purple and did some other stuff when I drove out to Indianapolis (and I kept it around 70 the whole way out). However, gas was so god expensive when I got out there ($3.50+ for 93) I just put in enough to last me the weekend and get me back to Ohio where prices were more reasonable.

However, I did make it from my apartment to my hotel just north of Indy on about 3/4 tank of gas (400 miles). I wish I coulda filled it out there to see if my mileage did improve, but oh well.

I do usually get around 320 miles to 3/4 tank of gas on mostly city driving (and it usually seems to need 14-15 gallons to fill it from 1/4 tank)

I'm wondering how many of you guys have to drive up and down a bunch of hills to go basically anywhere? I do, and I know that negatively affects mileage.

Also, I still wonder how any of you TC guys get 28-30 mpg on the highway, mine didn't even do that when it was stock except for a cone filter on the VAM.

That's a cool story, Brent.

Thanks, he tried for probably two years to beat my 32mpg, but he said he could never get more than 30mpg out of his.
I guess he needs to take a driving lesson from Eric. ;)

The best part of telling him my results was that I wasn't even trying, I was just driving normally. Of course it was all highway miles but I did run into some quite hilly areas and the turbo was on boost sometimes to maintain the cruising speed.

He never got over it, and when I see him occasionally I still bring it up. :evilgrin:

In his defense, he's not not a car guy, so he never grasped that my car was running in economy "Pinto" mode 95% of the time. He just knew it had a turbocharged engine and it was the "hot rod" version of the Cougar so his Thunderbird should be getting better mileage.

I would guarantee the pump is a lot more accurate than the gauge in your car. The "4-gallon reserve tank" is the amount of gas between when the gauge indicates full and when it actually is (and if your gauge is working correctly, there will be a further "reserve" between when the gauge indicates empty and when the car actually stops). When I had the disco-dash equipped '87 Sport I'd fill the car before visiting family in Yarmouth (200 miles away) and drive about 90-100 miles before the gauge indicated that I'd used any fuel at all. Once it started going down, though, it would do so quickly.

don know about that, my guage doesnt say F for any longer than it takes to get to 17 gallons. i mean when it says E it doesnt go 50 miles extra or anything, it usually means gas NOW.
