Ford F-Series Real World MPG Numbers

  • I know none of us are "happy"....but I'm about to trade up from my 3.0 (2006) Ranger to an F-150 4.6 super cab.

    Other than the EPA estimates for fuel mileage, how big a shock will I get with the 4.6? I don't get that great a mileage with my Ranger, approx 16 mpg on average.

    I drive conservatively (I'm 56, and my fast years are far behind me!).

    Any thoughts opinions appreciated!

    I have an 02 4.6 liter F-150 Supercab. I was only getting 16 mpg when I bought it. When I took it in, the service geniuses told me that it is the "breaking in period". I have never gotten anything different since... I know part of it is that I drive 69 mph on the freeway.
  • Thanks, jjess4. Maybe "69" isn't the good number for you...lol....maybe try 68 or 70!

    I'll likely get a Tonneau cover; studies shows that's about the best accessory (other than mechanical mods) that will increase mileage.

    Independent studies have shown no difference in gas mileage with a tonneau cover. Myth Busters did a show on it that you can google the results of.

    I thought that was about tailgate up or down (results: no difference). I don't think Chevy would install a tonneau on its Silverado mileage leader, unless it was actually doing something to help mileage.
  • I'm averaging 19mpg mixed driving with my 08 2wd 4.7ltr Tundra. My worst has been 15 and best 21.

    I have a '97 Ford F-350 pickup, 4x4 with a 5.8 v8 auto trans. The truck only has 54,000 miles on it and it in good shape. Does anyone know if I can do anything with the gas mileage? I average betweem 7 and 9 mpg all the time. The truck will pull a house with the 4.10 gears. I've done a k&n filet, 3" exhaust, synthetic fluids all the way around.

    Any one have any other ideas? Thank you in advance.

    I have a 1999 f-250 super duty, 7.3, that gets about 17mpg around town when I'm not towing. I pull a 5000lb camper, pull behind, with a 700 lb motorcycle in the bed, and then the mpg drops to 11mpg. I bought the truck used, so I don't know that much about it, Its got about 170,000 miles on it. Anybody know what could cause that much drop in mpg. My little f-150 towed the same camper and got 10.3 mpg.

    Try checking your tongue weight. Instead of towing the weight you may be carrying the weight.Carrying instead of pulling the weight can cause a huge drop in economy.The same wil hold true if you have a fifth wheel trailer.

    Okay geniueses.The question of the day is if you can drop the engine RPM by 100,200,300 how much econo change can you expect to get.This may be possible and still maintain 70 MPH,on the big road.Have a couple of ideas, that I am pretty sure can achieve the RPM drop.Does anyone know how much difference the drop will make?
  • Hello, I have the same 1997 truck (mine only has 87,000 miles) and it is a 4 door with the 460 engine...it has always been around 10 mpg or maybe 11 if truck is empty. I have owned it since 1999 and now this year it gets 4mpg and maybe 5 mpg if I really baby it along and dont idle at all in cold weather...what is the deal? did you ever hear what might be the cause? I have done regular maintemance....am now going to replace all plugs, wires, distributor cap fuel filter, etc. and see if that makes any difference....please email me if you have any ideas. Thank you

  • I will be purchasing an f-150 extended or crew cab truck in the next month. I'm just not sure if I want an 4x4 or 2x4. My situation is I drive around 4-5 k miles per month. I live in the mtn's of NC and fight snow and bad weather but I already have two 4x4 f-series trucks. Should I get a 4x4 or a 2x4? If weather is bad I can drive one of my less dependable trucks? But is the lack of maintnance and better gas mileage going to over throw the luxury of 4x4? Thanks, this decission is driving me nuts. Is anyone in the same boat, or just have a bone to throw?
  • Has anyone calculated the MPG of the new F-150 5.4 v8 4x4 while towing? I'm looking at buying one , but tow 5,000 pound camper. Was hoping it gets better mileage hen my 07 tundra.

    This maybe too late to help you but I just bought a 2010 F150 Super Cab 3 weeks ago with the 5.4 lt. V8 and maybe it helps you or helps someone like you or me who wants to buy a new truck. We just went on a trip to Cali. from Seattle last week and planned about 2000 mi. My truck was/is brand new and I really really love it. I was worried about the gas mi. since my last one was a 2006 F150 4.6 Super Crew and the gas mi. was not great 2 WD as well. I got 18+ miles per gallon. It also seemed to improve as the trip went on. The trip computer only went as high as 16.2AVG miles per gallon but filled it when we left without topping off and filled it again without topping off at the first half tank in OR. 36 gal tank and at half a tank I put in 18.23 gals. I got 323 miles on the first half tank so it was approx. 18 mi. per gallon. Take into acct. that I don't have a topper or toneau cover and no extras. I was pretty pleased. So I got about 640ish miles on single tank. I was also carrying about 1000 lbs of gear, not much but if I put a cap on it I bet I will get closer to 20. Also I seemed to do better around 75 mph. cruising about 70 to 80 was only a diff. of about 150 to 200 rpm.
  • Try calculating your fuel mileage by fillups, not by the dash readout. You'll find that you're only getting about 15 at best. I have a 2005 F250 Lariat FX4 6.0 with EGR delete, AFE Stage2 intake, Magnaflow 4" turbo back exhaust, 3.73 rearend, Amsoil synthetic front to back and I still can't make 16MPG. My dashboard readout will show from 18-24MPG but fillup calculations come out to 14.5-16.
    If your numbers are fillup calculations I have to say you got a diamond in the rough because the 6.0's are notorious for bad fuel mileage, worse than the 7.3's, and the 6.4's are even worse at 9-12.5MPG.
    Good luck with your mods. Some words of advice, go with SCT programmer, do not use K&N filters use AFE, AEM, Banks filters, get an EGR delete kit, a 4" exhaust system, and an ARP head stud kit is imperrative with these mods or you will be blowing head gaskets. This is from experience so trust me.
  • What kind of mileage can you expect from a new f150 supercrew 4X2 6 1/2 foot bed 3.55 limited-slip 20-inch wheels.
  • What is the rear end on this truck, I have 4.10 and it gets about 12.5 to 13.5 empty. Most of my driving is between city and highway. I realy drive highway but when I do I get somewhere between 14-16.5 (I only ever got 16.5 when the truck was brand new....driving it home from the dealer...and back down to pick up the car I used to pick it up in.
  • Let me add my dad has a 2009 f150 with 3.78 rear and a 4.6 liter and he gets between 19 and 20 mpg.

    I have a 2011 F150 Supercab with the 3.7 L. V6. I got that because I don't need heavy towing capacity and I was hoping for somewhat better gas mileage. I am usually pretty good at getting the estimated mileage on vehicles, if it is possible. Rather than 17/23 I am seeing more like 15/19 at best with an overall average of approx. 17. Is anyone getting anything close to the mileage they state for this V6? ronnoc
