[tjc78]

32? Really?? With what?

Must be the new "Crown Vic Hybrid" or something.

130 octane?

my old lopo got 24 mixed everywhere i went.. after the HO conversion i get anywhere from 17-21. i dont think the HO likes the 2.73 gears very much, seems to lug everywhere i go and the top speed is probably ridiculous.

Indexed pistons

I'm considering hoisting a sail on my boat.

Then I can avast the mizzenpoop.

Its bullshit that you pay full price for fuel with ethanol crap in it that just brings down your mileage. If there going to willingly lower your fuel mileage, at least charge less so it equals out. I run supreme in my civic and i went from about 35 to 44 mpg (however the 42 figure has been calculated over only 3 fill ups and the 35 has been averaged over a lot more driving so i expect the 44 to fall by a few).

In the pre-ethanol days I had a 73 VW Beetle with twin carbs, a mild cam, and a header. I beat the piss out of it and it did 27 mpg all day long mixed driving with premium 93 octane. It would get 22 mpg with regular, plus it pinged and ran generally poorly. At the time, regular was like 89 cents and premium was $1.05 or something. It was actually cheaper dollars per mile to run it on premium fuel. People used to look at me like I was nuts, putting high octane fuel in a rusted out 27 year old Volkswagen but it made a difference. It was something like 7.8:1 compression, which is stupidly low, but it was air cooled so the cylinder temperatures were naturally a fair bit higher than a water cooled engine so the high octane was actually useful.

Actually old epa rating was 19/31. You have to go steady 50mph to get 32mpg

What year and source please? The highest for any Panther I've ever seen is the 87s rated at 27 highway (old #s). Check out Fueleconomy.gov

There is a lot more to MPG than cutting everything out of the car.

Electric fan, gears, skinny tires, lots of aero mods- drop it, undertray, seal up the grille. Alignments also effect the milage, whatever you can to to lower the rolling resistance of the car will help. Lightweight wheels, aluminum driveshaft...electric water pump

My old vic was able to average 24mpg with 3.73 gears, free flowing exhaust, electric fan....

Phunky, never heard of that site before.

Amusing if there's any accuracy to the 2.3L Fox LTD being originally rated no better than a SEFI 5.0L Panther.

Still, has anyone actually gotten 30mpg from a 5.0L Panther?

That 31 is the raw data number that is used for computing FE for CAFE regulations. It is not a real world number.

I've owned a few Panthers, and my Grandfather has owned 5 none of them including his current 04 comes close to 31 MPG at any highway speed. Even achieving it at 50MPH on a level road w/o A/C is a stretch IMO.

I used to get no better then 27 on the highway with my 97 grand marquis, 3.27 gears and free flowing exhaust. One time i got 28 point something but there was no wind at all, it was on cruise the whole way back and i wasnt using any accesories .
