I'm going to direct you to www.crownvic.net for all that info. Having the PCM re-tuned will help the mpg and hp. These cars are built for comfort more than mileage.
I would recommend a Mustang v-6 auto for mileage.

It's just a SUPER-DUTY Mustang GT Sedan. 198K miles and still rolling HARD.
1997 Crown Victoria P71 SVT *** ex-US Marshall service (the CAR)
STOCK?? I bet it was modified.
13.26 @ 107.24 MPH 1/4 mi w/ me, tools, & full tank of 93 octane
I added CAI, NICHE 19 X 8.5 " wheels with 245/45ZR 19 rubbers, and completely rebuilt the front end with poly bushings, Kooks headers, 2 1/4inch exhaust, TCI 2200-2400 rpm Stall converter
.PLANS:: engine upgrade, 5.4L 2v stroker, rebuild interior in leather w/ buckets, thinking about turbos

I have an 07 P71 with 96K. Its very comfortable and it gets up-word to 26mpg in cruise control doing 70! Its when i put my foot into it which i do a lot, it drops way down. I opened the exhaust up from the cats all the way back with 2 1/2 inch pipe and magnaflow mufflers. I installed a fram air filter and keep the tire pressure 8 psi below max. I dont carry a lot of heavy stuff and i keep all fluids clean. Around town if you keep the rpms down or right ay 2000rpms you will also get good gas mileage. All in all i knew this beast would not get that great of gas mileage, so i just go and fill when needed and have a great time driving the vic--hope some of this helped--mike

Just wondering what I should look for. I know oil and tranny leaks are big in these cars, as well as rough suspension if it hasn't been taken care of. But Idaho doesn't have a lot of action, so I may end up with a great car!
