How many MPG do you get with a 1997 Ford F250 7.3 4x4, Auto tranny, stock suspension pretty much everything stock, and also how much of an imporvement would you get with adding a chip if you can, or straight piping the truck?

Thanks.

 

My 95 250 extended cab 4wd averaged 16 with 65mph and under driving.

My 97 crew cab 4wd is averaging 13-14 right now with 70-75 mph highway driving and a heavy foot in the city.

It has been my experience that a chip and exhaust mods won't help mileage. Your right foot has a tendency to hammer down to take advantage of the new mods!

 

So with like a bully dog module not a chip like that little screen and setting it on economy there isn't a very large improvement

 

Most people get between 15 and 20 MPG with your rig. A lot depends on your right foot. You can add a chip + DP and air intake and get a little better than you get now but you probably won't. It's like crack. Too much fun The biggest MPG gainer is speed IMO, I saw 22 MPG @ 55 MPH. It almost killed me to drive that slow but I wanted to know. I urned both tanks at that speed....on the eway.

 

Too slow again

 

Jim it must be your costume that's slowing you down!! LOL

 

I like that excuse...I'm using it hehe...I Thought it would be appropriate since it's holloween

 

I dunno I was just wondering I drive a 96 Bronco right now with 5.8L and I get like 10mpg and I wanted to stick with Ford but not a gasser and I heard diesels can get some pretty good gas mileage. It's a 1997 Ford F250 4x4 Crew Cab H/D with 139,000 miles and they want like $14,500 for it and I don't know to much about diesels so I was wondering what the best kind of deal is.

 

14-16 mpg for me.

 

Cuda and Tj are right. Your best milage will pry be at stock since everyone has a problem keeping their foot out of it once they get the mods in. I average around 16 during normal driving, and about 14 or so towing.

 

Is that a good price for that truck though 1997 Ford F250 4x4 Crew Cab H/D with 139,000 miles auto tranny.

$14,500, KBB says around 11,000 for excelent condition

 

It seems a little high, but if that sucker is in excellent condition it'd be worth it. 139 on the ticker is pretty low. That thing is pretty much a baby still.

 

18-20 regularly regardless of town or highway over all with highway driving consistently yielding the higher mpg. I keep it just under 2k on the highway which puts me at an indicated 65 mph.
Early indications are that the 15.6k mod (a la c00nhunter Joe) might be boosting the mileage a wee bit in that I have had a heavy foot since the mod with no apparent decrease in mileage. But, I have only run a tank or two through it so far and more time is needed to get cumulative results.

 

What do you mean by it's still a baby, like I said in my previous post I don't know pretty much anything about diesel trucks/engines, would it be worth it to go with a diesel over a 5.8l right now?

 

A diesel engine can easily go up to 500,000 miles without anything major breaking down on it. There's quite a few guys on here that have over 400,000 miles with original parts. Basically, if it's been treated good that engine will last forever.

To choice a diesel over a gas pretty much depends on one thing nowadays. Are you going to tow stuff? A diesel gets awsome milage when it's pulling something compared to a gasser.
