Hi!! I currently have a Ford 150 4x4 crew cab and it gets terrible gas mileage. 13 best on the highway and only 9 best towing my camper. I am looking to get a F250 Super duty crew cab. I need to know what will be the best MPG?? a V8 with the 5.4L gas, a Big V10 gas or the diesel?? Does anyone know from their own experience what MPG these all get??? I know diesel will most likely be the best BUT it is more expensive to buy at the gas stations as well as the truck itself!!! At the dealer a new diesel is $7000 more then a V8 5.4 gas. Can anyone help me with some definate answers pleaseeeeeeee. thank you!!! :-)

go with a diesel hands down. i wouldnt recommend anything newer than a 2006, that way you will avoid all the emmisions crap and will get far better mileage. mine is an '05 dodge 2500 cummins w/manual. empty i get about 20-21 avg in warm months, about 16 in winter. you may pay more right now but the resale on it will be far more than with the 5.4 petrol. jm.02

The new Dodge Cummins is 6.7liters to the Ford Powerstroke 6.4liters. The older model Dodges were 5.9l compared to Fords 7.3l or 6.0l. None of them get as good of mileage as they did in the late 90's. The power and towing capacity wars along with EPA mandates have killed the fuel mileage!
At 25k miles a year I compared a 2008 V10 to a PSD, exact same options, I used 12 mpg for the gasser and 15mpg for the PSD and it would take 7 years to break even at todays prices. This is not taking in to account way higher oil changes for the PSD. Don't get me wrong I love the diesels but they are not as good of a value as they once were.

the diesel is a great idea if you're looking for mileage, and diesels are known for their towing power. although the price of diesel right now is a bit discouraging ($3.89/gal here in CT), the about 40% gain in mileage over the gas counterpart is a welcome gift.
and if the price is an issue, there's always the possibility of a used truck. My 1999 F350 has the 7.3L Powerstroke, and it's running just fine at 238549 miles. and it'll manage 13-14 mpg with our 10000lb horse trailer, and 21 highway mpg without it

Diesel should get the better mpg all around, depending on its size relative to gas ones. But what has been the diesel price in your area, if close to gas then it's likely worthwhile (mpg is only part of the equation).
Should be able to look up relative mpg fairly easily online - even the Ford website should list it. Note, often diesels get closer to their EPA rating than gas for some reason.
Haven't heard the one of needing 150,000 mi. to break-even with diesel...usually not that much more expensive than gas.
Other comment, why Ford...there are better makes when it comes to MPG??

If you plan on keeping the truck for a long long time, I would buy the diesel, I talked to a person at a car dealer and he said that in order for it to be worth buying a diesel, you will need to drive between 150,000 to 200,000 miles before the diesel becomes cheaper than the gas model. If you plan on getting rid of the truck before that then I would go with the gas model. If I had to choose I would take a Dodge with a Cummins because it's got an inline 6 compared to the Ford's v8, 6 compared to 8, less cylinders=more gas mileage, and Cummins offers great power in a small package, but it's your decision.

regardless of what brand you go with I would choose the diesel. if you plan to keep it for a truck a while it may be good in the long run because at least with the diesel you have the option of converting to veggie oil or running biodiesel as opposed to just gasoline.

I have always had Ford trucks. Never have I done better than 16mpg on any of the diesels that i've had.I tried driving like Ms. Daisy to using additives to driving like I'm headed to a fire. There really wasn't much difference in mpg between any of these methods. I do pull trailers with considerable weight frequently. I put a programable chip on my'00 7.3. did notice an increase in mpg running empty, but that changed with a load. Beside the usual "get a cummins" or "Like a rock" comments is there something I am missing or doing wrong to be getting the lower fuel economy

If you are really after juel economy, get a disel and re-program the computer chip, will get around 25 MPG and it will pull even better.

Hi!!! I have 99 F350 V10, 6.8L with only 53,000 miles on it, regular cab with 4:30 ratio and I only get 7 mpg in town and the best on the highway i have seen was 11 mpg keeping it at the speed limit. I think 35 inch tires are killing my mpg and i do drive it hard in town. My friend has super cab with V10 and he is getting 14 on the open road with stock tires. I love diesels (cummins and 7.3 powerstroke) but there is not a big difference between V10 and 7.3 diesel in power and i am talking stock to stock. I am thinking of buying a new 5.4 for little better mpg and i would like a new truck. The only reason I am not looking at the diesel is because its about 70 cents more then gas here in Maine and i make short trips alot which kills a diesel and I can't wait 15-20 minutes to warm it up. Any info on 2008 super duty with 5.4 like mpg and other stuff anything THANKS

Another point too....longevity. My local city's handicapped bus service uses 15 passenger buses equipped with both the Powerstroke and Triton 6.8 engines, and are still in service after 750K miles. Take care of em, and either engine will last for a couple decades.

In a super duty, economy difference will be MAYBE 3mpg with any engine. So if you figure you can justify that extra $7000 over the life of the truck, so be it. The 5.4 will probably get you 18.5 on the hwy at the speed limit, the 6.8 will probably get you 18, and the deisel might get you 21.

19-21mpg on a 4-door F-250, with a 6.0L diesel, unloaded. 12-14mpg with a 10K pound load. These diesels have more torque for pulling. If they didn't, truck drivers would be driving gas burners.

Most folks that I know with powerstrokes get about 20 mpg. Another good thing about diesels is that you can convert over to used cooking oil and drive for free.

Unfortuately a car will not do for me. Im looking at a 250 diesel to tow my camper. Right now my 150 will do it but the gas milage is down to 8 mpg towing and you can tell there is a load back there. My trailer might be a little to heavy for the truck... PLUS i have 4 medium/large size dogs that ride in the back in crates and unfortuately they wouldnt fit in a car. Thanks for the suggestion though! Any other thoughts on diesels vs. gas 250????

I had a couple of Ford trucks before I went GM. The F-250 SD with the V-10 got at best 11.6 mpg. The F-150 SuperCrew with the 5.4 V-8 got at best 16 mpg.

My present ride (Hummer H3) has topped out at 19.863 mpg. :)

A good diesel truck will hold its resale value twice as long as any gas engine pickup will. A Cummins engine will give you the best fuel mileage from a diesel engine even more so when towing. If you’re stuck on the Ford brand then look for an older 7.3 and not the newer 6.0 as they have to many problems and they don’t hold their resale value at all.

I also have an F150 4X4 crew cab, I love my truck, but the gas milage sucks, I am getting 14.6 miles per gallon with a conservative driving. I have the exact same question you are asking and the only thing I have to say is that if you do not use it for work then you should get a car. I have driven diesel cars many times and the MPG is great. If you need the truck and you are buying it then I would go for the diesel.

Alot depends on how you use it. If you tow heavy loads most of the time, and/or drive 50,000 miles a year, a diesel motor is the way to go. If you only drive 10,000 to 12,000 miles a year, a gas motor is cheaper. And, don't forget, diesel fuel is now 15% more than gasoline at the pump, so this must be factored in, as well.

You are right about the cost of a diesel motor and fuel. Mileage is better but that should not be the decision driver. It will take for ever for a retrun on investment. however, if you have a need for the higher torque requirements that a diesel offers, llike towing, then I woioudl get the diesel. I own a 1 ton quad cab dodge Ram Diesel dually that gets 23.6 MPGon the highway with no load. i get 15.8 MPG towing a 40 foot 15,000 LB camper. I got thrt diesel for towing and it is great!

I own a Ford F250 super duty crew cab, 2001, 5.4 Liter. The best mileage I've gotten is 15 mpg all highway. I get about 12-13 around town with lots of stop and go and that dips when the weather gets below 25 f. I get about 9 or 10 pulling my camper on country roads or ex-way if I keep my speed down under 60 mph. The engine is A tad undersize for my 8500 lb fifth wheel, but if I am patient it pulls it fine. The newer 5.4 liter (2005) has the dual overhead cam which will give you more hp, torque and better gas mileage, my next truck will have that.

If you want Diesel and are not dead set on Ford, look at the Dodge Cummings. They give way better mileage then the Ford and Chev. I have a 5.4 and get around 16mpg hauling my camper.

With the prices at the pump i would opt for the V-10. Not only that but the new twin turbo 6.4 is not that great on MPG. Some say it doesnt get better than 14!!! Diesel's cost a little more but you get it back when and if you sell it. If possible look into getting the 5.4 with extra tall gears.

The 5.4 and the 6.8 V-10 are notorious gas hogs, a lot of people dislike the noise of a diesel engine and prefer the gas burners. It is a hard choice, I have seen both gas and diesel engine last over 200k miles.While the gas engine may only get 15-18 mpg and the diesel 17-20 mpg you need to decide how the truck will be used. If you drive around empty all the time gas may be the way to go, but if you pull trailers or haul a lot the diesel is a definite advantage. I too have a F350 with 4:10 axle and it has always produced 17 mpg on the highway empty and it has 227k on it, it drops to 10-12 depending on how much is on the trailer.

my personal opinion leans toward the diesel. and if you are not so hot on spending the $7000 premium, there's always the possibility of a used truck. diesel engines are renowned for being long lasting and durable, so even one with 100000+ miles would be fine.
i have a '99 F350 with the 7.3L, and i can get 20 mpg unloaded at a steady 75 mph. when we were pulling our 8700lb horse trailer at 65 mph, we averaged about 14 mpg.
the only disadvantages; these trucks are hell to park, and where i am in CT regular gas runs $3.23/gal, while diesel is from $3.70/gal to $3.99/gal

I've got the 6.0 too. I've got an SCT tuner that is supposed to arrive today in the mail and I'm drooling over getting the thing in there. I'm getting about 14-16mpg but I'm a 350 with dual rear wheels and I also have a 4.10 rear end so my highway revs are a little high. Throw in the fact that I often cart around an 1100lb Yamaha Rhino in the bed for work (land suveyor)and that will get me down to 14-16 pretty easily. I'm anxious to see what I get back with the programmer. Most have said 2-4mpg.
Still, in comparison my Tacoma with a V6 got about 12mpg with the same load, I had to pull a trailer to do it and the engine was screaming bloody murder the whole time!!!

I have a 6.0 diesel and get between 16 and 21, depending on driving habits and age of motor oil. I do have the banks 6 gun with PDA which helped about 1.5MPG and of course made the truck more drivable.

When i tow my 23.5 foot ski boat (6500lbs w/trailer) i get between 15 and 16mpg.

Gas mileage is for sure much better with the diesel. I have spoken to several V10 owners getting 12MPG and regretting their decision. The 5.4 doesn't have enough power to pull a big load and carry the heavy super duty.

Diesel 6.0 or 7.3, as the new 6.4 diesels are not getting good MPG at this point. A 6.0 will get 16-20 MPG and can get 18-22 with a good economy tune from folks like DJ's diesel or Elite disel. More power, more MPG, more longevity and when towing a big load, more comfort with the engine not having to work as hard IMO. Keep in mind too that a brand new disel will take 15,000 miles or more to break in and fuel economy will increase at that point. Buying an '07 with the 6.0 would save $$$$ and already be broken in as well as just flat out be more efficient from what we are seeing with the 6.4's right now.

Obviously like a few folks said, make sure you really need the big truck but I'd definitely buy used. FOlks are getting rid of diesel trucks they bought for prestige and have now come to grips with the fact that they don't really need them! Mines a work horse so I have no problem justifying it to myself.

Personal preference. Diesels may cost more to buy and at the pump, but you probably will save in the long run. First, any size diesel will beat its gas cousin in fuel economy when towing. So if you're not towing, you will probably get the same or worse milage with a diesel. Rule of thumb: if you tow a heavy trailer (7000lb+) over 80% of the time, opt for a diesel.
Second, RochBear is right. No matter what you tow, diesels have incredible longevity; the body is almost always ready for the junkyard before the engine.
A gas V10 is overkill, especially with rising with gas prices. If you opt for gasoline, a gas V8 can almost always handle what a V10 can; what usually matters in this situation is gear ratios, suspension stiffness, and what type of hitch is in use. A bigger engine is no good if the chassis can't accomodate the load.
Bear in mind that all 2500 trucks have stiffened suspensions and fewer safety features than a 1500 version. I rode in my friend's Ram 2500 and the ride is HORRENDOUS! He says it's easy to get used to.

Well i bought a chevy duramax to replace my identical chevy with a 6.0 gasser. The gas truck got about 8mpg and my diesel in the same driving gets 11 mpg. Highway the gas got 15mpg and my diesel has got up to 23mpg. Only bad thing is right now diesel is .50 more than gas per gallon.

Back in the early 90s I traded in my F250 and sold my 24ft travel trailer. It was cheaper to haul the family in a Dodge Caravan and stay in motels. No tin walls, no wind blowing out the pilot on the heater, comfortable beds that someone else made. And the wife rarely cooked dinner in the thing anyway.

I like this, you're asking what you can do to get better milage.

I know you're looking at a Ford, and I have a Dodge, but I can tell you what I am getting with a Ram 3/4 ton with the Cumins and a 6 speed manual. Around town I get about 24 (empty), 21.5 at 55, and 19 at 70 on the interstate.
When I am pulling my 7000 # trailer, I get about 16 (around town, 55 and 65) doesn't seem to matter much, however, if I go 70, it drops to terrible.

It will depend on how many miles you put on your truck. Diesel fuel is more expensive (for now) than gas. But you get much better milage. A diesel does need to be warmed up in cold weather, and cooled down (for a min) if you've been working it. But my experience is Everyone who owns a diesel loves it, and will never go back to gas. Plus the longevity of the diesel is great. Most people don't even touch the engine until there is over 250,000 miles on it. Most over the road trucks have over 1,000,000 miles on them before they get traded in.

One thing you may want to do, is make sure the rear end ratio is "right". It sounds like your trailer isn't real heavy, so you don't need a ratio for pulling stumps. That will make a big difference in your milage.

My choice would be not to get a truck at all. Do you REALLY need one? With oil approaching $100/barrel, you are going to see $4/gal soon. Soon, you will be paying much more for life in general given the falling $ in combo with higher oil prices. Can you really afford to have that inefficient, gas guzzler around?

My choice would be the diesel. I've got a 2000 7.3 diesel. I know there is a difference between that engine and the one offered now but, I can only belive that the new engines are better, even though not a big. My truck has 117000 miles and I average 15-17 driving at 65-70. If i slow down just 10 mph the milage increases to a steady 22 mpg +. have your truck serviced regularly and the reapirs will be minimum.
except for tries and batteries, my total repair bill has bee in the $600 dollar range. I'd say go ahead, spend the extra money and have your truck serviced regularly and you'll be a happy camper.

The diesel will get significantly better mileage. The question you need to consider is if you will keep the truck for enough miles to pay for the price difference. Generally, it will take around 200,000 miles or even more depending on the price disparate between regular gas versus diesel fuel.

My 2005 F250 6.0L Diesel consistently gets 18-20 mpg unloaded, 13-15 pulling a trailer.

The V10 will be cheaper initially but the diesel will give better mileage. I have a E350 SD EXT w/V10, its not used for a tow and I get on average 14ish MPG overall. For the F250 go with one of the bigger and more powerful engines. You did not say if your current F150 was a 5.4 or not. I would doubt the 5.4 in an F250 would be any better than your current one since the 250 is heaver and the engine has to move it as well as your camper..
