    How is your F-Series truck treating you at the pump?? Are you beating those EPA estimates in the real world?

    I get around 18 mpg highway, empty under 70 mph. Over 70 mph drops me to 16.5 mpg. Loaded with my Jeep on a 16' flatbed, probably grossing about 11,000lbs, I'll get around 14 mpg. Pulling a larger trailer, grossing over 15,000lbs, the mileage drops to around 11 mpg. This truck currently has 165,000 miles on her.

    Those #'s are very consistent with what my grandfather gets with his '97 350 7.3L 4x4 (non-dually). The most significant drop in mileage comes @ speeds over 70mph (which he does frequently). He has noted that his 35' dual-axle 5th wheel trailer nets him worse mileage (11-13 mpg depending on winds) than his 40' quad-axle boat trailer for his 32' cabin cruiser (~14 mpg), even though the boat weighs better than 3x as much. In his words, "the boat pulls much easier."


    In my opinion, these are all very good #s considering I get about 11 mpg with my '69 Chevy 307 running empty and drops fast when I pull a load, and I would be crawling if I pulled that boat trailer while he pulls it at 65 mph even up some sizable grades.

  • I drive this thing like a baby, rarely gunning it and easy on the breaks and still can't crack 15 mpg even on the HWY with nothing in the bed.
  • I have a 2004 Ford F-250 Crew Cab 6.0 diesel. It has 3.73 gears, 35" tires and a 5 1/2" lift on it. My average gas mileage is 13.7 highway, 11 city and 5.6 towing. When I took into Ford they told me that the towing numbers were really low, and chances were something was wrong. When I picked it up they told me that NOTHING was wrong and that the mileage is what it is. Has anyone heard of this before?


    Even before my modifications, the best I got was around 14 highway. There is only 6700 miles, and the service guy said to wait until it breaks in, and then the mileage should start to go up??

    calculating correctly - did you install a new speedo gear to correct for the 35" tires? Those are 3-4" taller than stock, throwing off your speedometer by around 10-12%, depending on what tires came stock (235/85-16, 265/75-16, or 265/70-17) - you're traveling a lot more miles than your odometer is recording...


    Secondly, if you're like me, you're not driving like a grandma - like me, you've probably done Banks or Bully Dog exhaust, and love to romp is to make it make noise...that flat KILLS your mileage.


    Combine incorrect calculations with less than conservative driving, and I'd say you're doing pretty good.


    The towing mileage? Those 3.73 gears are too tall to try to tow with 35" tires - you need 4.11s or a little higher to adjust to normal operating ranges (engine and transmission) - you're working them pretty hard with the 3-4" taller tires and no change in gear ratios.
  • I thought that you no longer had to change speedo gear to adjust for larger tires. All the dealer needed to do was program in a new value for the larger tire circumference, and then the computer adjusts the speedo and odometer accordingly for the new number of revolutions per mile.
  • driftracerdriftracer Posts: 2,692
    can't do that for non-OEM tires, you need a piggyback ECM to do that, and a laptop - I would seriously question the ability of any technician (in a dealership) to be able to do this - having that adjustable software actually voids your warranty...


    Even if the recalibration was done, that's still a lot more work for the engine and trans, especially when towing - just because the speedometer may be accurate, it doesn't account for the extra weight and rolling diameter your engine has to push around, especially when towing.
  • mullins87mullins87 Posts: 959
    I'd say you're probably doing about as well as can be expected considering your current setup. I agree with the others that you need to regear to 4.11's. If my "off the cuff" calculations are correct, 4.11's should put you pretty close to factory gearing.


    I have a Jeep Wrangler with the little 2.5L 4 cylinder, 4.10 gears and 31" tires. To the best of my knowledge, it has never broken 15mpg.
  • Just bought my first 2005 F-250 Crew Cab Diesel with the 6 1/2 foot bed. I really enjoy my truck. I just wished it came if a larger fuel tank. Has anyone out there replaced their stock fuel tank with an after market one? I've seen one on the internet that holds 46 gals. Any advise?
  • just how many gallons does your current tank hold?


    when I bought my '04 F150 it had a 35 gallon tank (factory upgrade) as did many trucks on the lot.


    that's plenty big for me
  • connon1connon1 Posts: 15
    04 crew cab with short bed holds 28 gallons. When I got mine I dont believe there was another tank option. I would rather have the larger tank.BTW, paid $2.16 per gal. for last tankful here in NJ.Paying that much almost seems like I have a bigger tank.
  • I did a couple of things on mine (2001 5.4L 4X4) that helped a bit. First go get a K&N filter, not a huge help, but it is noticeable. Second get something over the bed,(dropping the tailgate doesn't help) I put a soft tonneau(?) on mine. Don't forget to check tire pressure as well. Driving from Utah to Washington state, I managed 19 mpg on one tank, though 17.5 to 18 seems the norm (HWY). It still sucks in town, 12.5 approx. Something else to remember as well, the new design, while cool, added around 500 pounds to the truck; this can't help milege either. Take heart though, every Dodge truck owner I've ever talked to has it worse.

    I have an F-150 with 3500 miles on it. I get 12.6 to 13.5 in mpg in town and 15.3 mpg on the highway. I think this is in line with what most people are getting ??
  • I have the same problem with my 2005 f-350 crew cab. I get 12-13 mpg normal driving. The best I got was 16.5 when I took a trip to Chicago from California. I only have 8200 miles and am wondering some of the same things. I just met another guy in my town who has an '05 and is only getting 13-14 also. My dealer just told me "You should be getting better than that." Hopefully somthing can be done because I feel cheated, due to misrepresentation when I was buying.
  • Wrightman,
    F350 CC and you're getting 12 -13 mpg, that's really not all the bad. You don't say what engine or whether you're a 4x4, or 4x2. or long bed or short bed. You're a lot heavier, and have a bigger payload than the F150 yet you're getting comparable mileage! Still quite painful though when you have to fill up.

    i had a '00 expedition rated at 12 city 16 highway. usually got 12-13, unless a long trip then 16-17. that's about right.

    '03 F150 4x4 w/5.4L No matter how hard I try, I get about 12mpg in mixed driving and maybe 17 in mostly hwy driving: (
    Have about 11k miles on it and running full-synth 5-20.
  • I have an '03 F350 SuperCrew KingRanch 6.0L Powerstroke with 19K miles on it, with a fiberglass rear lid. I average ~17-19mpg unloaded hwy and ~12-13mpg hwy pulling a 27' travel trailer. Unloaded City is ~16 mpg.

    I've been pleased with these numbers, and I can say I don't baby it, but I also don't jump all over the gas either.
  • mclmn35mclmn35 Posts: 1
    I'm trying to decide which truck to buy. It's between a 99'F-350 diesel, crew , 4x4, longbed with around 100k miles on it, or an F-150 4.3L V6, crew, short bed, 4x4, with about 21k miles. Which do you think would get the better mileage? And do you think the 150 would tow much?

  • Okay, not too familiar with the 4.3L V6, what year? Anyway, with the 4.6L V8 the F150 has a standard towing capacity of ~6000Lbs, Maximum of MAYBE 7000lbs, but you'd be pushing it. I couldn't tow a 4700lb (dry weight) travel trailer with a 2000 Expedition with a 4.6L comfortably, even though it had a standard towing capacity of 6000lbs.

    With the '99 F350 7.3L Powerstorke, you get 12,000lbs towing off of the "bumper" and up to 14500 if you use gooseneck/5th wheel.

    Fuel mileage.....figure 16/20 for the F150 and 14/18 for the F350. 100K miles on a diesel is nothing, the engine is just being broken in. If it were me...I'd go for the F350 Powerstorke, but that's my $0.02. You'll be able to drive it just as long, if not longer than the F150 with 21K miles AND you get tons more towing capacity and the fuel mileage doesn't drop that much. If you chip it, you'll be able to get better fuel mileage than the F150.
  • xwesxxwesx Fairbanks, AlaskaPosts: 13,078
    Yeah, I'd have to agree. Honestly, I cannot understand why you would even be comparing these vehicles. If you think the F150 would handle your needs, then the F350 is absolute overkill. Vice versa, and you're wasting your time even considering the F150; V-6 OR V-8.

    I currently own a 2004 Ram QC 2500 4x4 The gas is killin me. I am looking at a 4.6 4x4 SUPERCAB F 150. I currently average 12mpg. 1/2 city 1/2 highway. With the lighter truck (I'm sure the SC is lighter than the QC) what should I reasonably expect. I've looked at Colorado and Frontiers but I have always had full size trucks and don't know if I could adjust to the mid size. I could even live with a Regular Cab if the mpg was better. Any help would be appreciated.
  • wpalkowskiwpalkowski Posts: 493
    Unfortunately, I don't think any full sized pickup is going to alleviate your wallet pain. Even if you get 15-16 mpg with an F150 it's still going to be expensive - there's still all that mass to move around, (I think cab size only account for a few hundred pounds in weight difference) and pickup trucks are about as aerodynamic as a garage door :cry:
    You could switch over to a diesel, they get better mileage than a gas engine pushing around the same amount of weight. However, diesel engines are more expensive to buy up front and in my area diesel fuel is about 30 cents more expensive per gallon than gas.
    Don't know about midsize trucks, do have friend with a Ford Ranger who consistently gets around 20 mpg - but I could almost fit his truck in the bed of my F350.
    You could do like me. My truck is a V10, and it gets 10-11 mpg in the city. It takes 39 gallons to fill it - it's pushing close to $100 for a full tank of gas. :( Luckily,It is not my daily driver - it only gets used when I have to haul or tow something now. My other car is an an older Honda :blush: that gets ~25 mpg in the city and ~38-40 on the Highway. :)

    thinking of trading in my '02 F250 for a new F150 because gas (87) in northern NM is now about $2.50/gal. Ratings for '05 F150 supposed to be 15/20 mpg. Anybody getting close to that in newer F150? My 250 (4x4 crew cab long bed; V-10, 6 speed manual; 77,000 miles) has consistently gotten 14 in mixed driving, and up to about 17 in Hwy only in warm weather and 12 to 15 in cold. Great truck, but if new F150 numbers are accurate, I can save up to about $1,250.00 a year in cost of gas, more if prices keep going up.
  • Or, if you don't want to sacrifice size, get a 250/350 Powerstroke, I consistently get the 15/20mpg out of my '03 F350 SuperCrew 6.0L Powerstroke. I can get 22 on the hwy if I cruise a steady 65 mph......

    98 f150 5.4 L 4x2 super cab

    Since taking my foot out of it a bit and airing the tires up to 35 psi and not running the A/C I have been getting an avg mpg of 14.16 after averaging 4 tanks of gas.

    Usually this truck was about a 12-13 mpg with my driving habits.
  • rangerx93rangerx93 Posts: 1
    FYI: You cannot accurately calculate gas mileage by guessing how much gas you have in the tank (based on the position of the gas gauge needle) and dividing that by the trip odometer amount. It is most accurate to calculate immediately after fill up.

    Currently my truck has 62,500 miles on it. 85/15% (City/Highway) I get 14.5 MPG. During short 1 hour trips on highway at 70+ MPH I get 16.5 MPG. Best ever 17.9 MPG. Pulling 2,000# trailer 200 miles over light hills in S. Alabama 13.1 MPG. I am thinking of buying a 2005 Tacoma Reg prerunner.
