My Explorer gets 16-17 (4.0 OHV), and My Tbird gets about 19ish. However, I once managed to get 29 on a 100-ish mile trip.

My explorer was about the same. The best I ever seen from the cougar on a road trip was 28.

My E-250 goes through about 40 gallons (1 tank) on a 6 hr trip....... Just thought I would toss that in there
And that's with it empty... It's about half with the 2000 lbs of tools in it

I eat up about 2 tanks of gas a week but I also drive like 700 miles/week. Not sure on the mog but it's not good, running rich and trans is slipping. All I know is the second that aod goes, it's getting a 5 speed!

What does it do for mileage now?  If...... you can keep your foot out of it??

Mine is stock now and will be fairly modified later.:evilgrin:

 
I've never checked it to be honest.  I will find out this summer when I take it on Hot Rod Power tour....should be a 800+ mile trip.

I averaged 32 once in my 5.0 going to pittsburgh a few times in a row. Its a highway car runs maybe 8-900rpm at 65mph. My uncle only drove it between the wal mart stores he operated which was hundres of miles a day, by the time I got it, it has like 263k miles, all highway.
'twas the days before my cell phone camera, noone ever beleives me.

Granted around town, its like 16-19

Either way is better than my 4.0 explorer, it maxed out 21mpg going to cincinatti a couple times in a row...

I got 35 mpg in my 87 cougar with a 3.8L bone stock.  That was driving like a granny and 55mph(1500 RPMs).  That was just to prove I could get good mileage.  But most of the time I'm getting any were from 30-23mpg highway.  But my car only has 35,000 miles on it now.

My 3.8 could get 33-34 on the highway. Driving it sparingly. The 5.0, well it gets 26-28 on the highway driving it carefully.

Driving real careful, I got 35mpg a couple of times according to the computer. My overall best averages were when I was sticking to 60-65mph and way loaded down. Best calculated from the pumps was about 33mpg on a 100 mile round trip, about 90% freeway.

Generally, 22-28mpg freeway, and 14-19 city. I did alot of driving city using my thunderbird for pizza delivery for about 8 months.

This crown vic  me off. It has lower gears, and weighs slightly more then the bird, but with the same engine and tranny combo, I would still think it would get close. Itshiznitting about 14-16 city and best so far of about 22mpg freeway. I basically average about 18mpg no matter how I drive it. There is something not running right with it, but it passed emisions with flying colors. Just haven't gotten around to it.

I honestly dont think you could exceed the cost of a new car buy installing new *stock* parts everywhere in your coug our tbird. Its just plain impossible. You could revamp the entire drivetrain/engine/suspenstion and still come out ahead.
