How many mpg. with your 7.3?

Thanks

Sty

 

I have ideal driving route to and from work..65mph 30 miles highway 5 miles city..I get a little over 20mpg...

Best I ever got 22.67mpg..this is with propane..

On #2 only best ever was 19.99...avg about 19mpg...

 

My best has been 20.6. That is bone stock, right down to the paper filter. On the highway with cruise set about 68mph. The truck is a '02 350 SRW, CC, long bed, 4x4, auto. Looking for better with K&N and muffler delete. Some day I'll chip it. That's what I love about diesels, they take SO well to mods!!!

 

How in the heck are you guys getting that kind of mileage? I drove a 99 4WD estracab PSD the other day and averaged 13 mpg. This is not pulling anything but its own weight.

Watch out foer the rattling T/C on the 99's...4WD is worth 1~2mpg...

Mine route is idea condition...For fuel economy...

Heres the kicker, 2X stock power and still getting about 1 mpg less then stock, sounds a whole lot better as well..

 

18 to 22 and I push it all the time. I like to watch the boost gauge.

 

Seems no matter how I drive, I get around 18 mpg. I have added the mircro tuner (tow safe) program and put in an air force 1 intake system and, even though I get same mpg, the truck runs a lot better/smoother. I can't seem to get any better than that.

Also, how many of you top off your tank? Me, after the gas nozzle turns off, I put in (slowly) about another 5-6 gallons of gas. So now I can go a little over 500 miles on a tank.

Just did a round trip from Kansas City, MO to Roanoke, VA on a week old 03. Running in the 70's (average) down and back averaged 17. Flatlands through MO, IL and IN average = 18 and KY, WV and VA average was 16.68. Had we throttled back to 65 - I'm sure we would have gotten close to the 19-20 mpg range

 

Hey Mach1...could you post a pic of your Mustang?

 

Hey, the mustang is in restoration mode...I need to take all kinds of before pictures, I used to autocross it in the late 80's, early 90's...I have a couple photos on the website, but it is rough right now...I am going to strip it down to bare chassis and have it dipped...go through the whole car...especially the engine...stick a T56 in it, Was even thinking about an indepedent rear from the t-bird/cougars..

Runnert, drop your tank and harpoon the tank mod...

There is a vent tube in there, cut it off, do the tank mods while you are in there..

I can empty mine, put the nozzle in and it will fill to 32 gals and click off, add another 1/2 gal and you are done...from 20 minutes to 4 minutes...ITS worth it...

 

best of 21.
Currently ave 18.6. Last was 19
Set the cruise at 68 to avoid tickets.
On a trip doing 75-80 I still ave about 17-18.
Better milage than my former 00 F-150.

 

Those are some great numbers there, about the same as mine..
