I'm driving to Destin FL on tue, this will be a good test to see if i'm back to getting 16 + MPG after cleaning the EBPV and tube.

 

2001 with 3.73s rolling 305 70 16s and I get 15-16.5mpg mostly back roads babied in the summer and about 10-20% less on winter fuel.

Highway at 65-70mph at about 1900rpm I'll get 17.5-18.5 if I'm good to it.

Pulling our 2 horse bumper trailer at 60-65mph (and it tows like a brick), I think I was at 13-15mpg.

 

I drove 250+ miles all interstate between 75-80 mph and got 18.83 mpg all hand calculated. If I kept it between 55-60 I could easily get over 20 all highway but that is very likely not to happen because I don't drive that slow. Also if I hit a few stop lights on the way it hurts mine pretty bad. I also was curious about all this great mileage but once I checked it all non stop driving mine does pretty well. Its very rare I drive all highway so mostly I get around 16-17

 

My "new" truck has 174000 on the odo and Im getting 12mpg - all city stop and go. Im running Stanadyne Pro in every tank. I have already added a banks cold air intake. Saving up for a DP tuner (80E) hope that will get me boosted up a little bit. I'm looking for 15 in the city and 18-20 on the highway.

 

That is the 80hp Economy setting on my DPTuner. Get one if you can, you wont regret it.

 

I have an 02 with 165000 on it, city driving is 13-15 depending on my foot and 16-17.5 highway. That's with 6637 and superchips on fuel saver. I discovered a plugged ebps tube and sensor yesterday though so hopefully this clean one will get me near 18-20. Is injectors really the secret to joining the 20+ mpg club? Many members I've met on here are attaining that type of mileage with not only a helium filled right foot but with upgraded injectors. I've been scratching my chin about this but there awfully expensive to trial and error.

 

Ill be headed there on sat with my 99 7.3 with DI chip on 80, 3.73 on 285/75/17's. Hopefully I can break the 21.3 mpg record Ive got so far. On the way back Ill run it on the stock setting and see what the difference is

Edit: Ill be driving there from Kingsville Texas. What a trip it'll be.

 

Truck in my signature does well. This summer on a trip to SD we got 22.5 as a best with the average at 22. In the winter (MI) the average is around 19. Normal summer driving is 21.something. Mileage is always calculated by hand as I have no lie-o-meter.

 

seems like those without a tuner are getting 12-13MPG!

 

I don't have a tuner, just intake and exhaust and I'm in the mid teens most tanks.

Truck is prepped for a tuner in that it breaths well and I have the gauges for EGT and Bosot, just need tranny temp etc. Just haven't found the need for more juice yet, I only tow a horse trailer with it and it isn't like it struggles......although I do enjoy dropping a dark cloud from it occasionally so I can see the power being addictive.

Edit......Auto with 3.73s rolling 305s......

 

some more detail on your trucks when stating mileage would be good fellas, such as *manual/auto*

 

My 03 gets almost 17 0n the highway, 9 to 10 pulling my 5'er. It has 3.73 gears and the LT235/85/16 tires.

 

had to go around bad weather. maybe 2-300 mileslonger than shortest route.

 

I was getting 13.5 with my 2000 F350 DRW with 4.10 gears

 

I'm getting 14.5 mostly highway/some city on my 2000 F250, 266k miles, auto trans. Only mod is a 6637 filter. I also use stanadyne treatment. When I bought the truck 6 months ago I was getting better mileage. Maybe I need to clean my EBF sensor tube?
