I have to get rid of my 95 F-450 I'am using the truck for a daily driver driving to a job that doesn't require the truck. I'am just going to run a F-350 overloaded when I need to haul some heavier loads.

I was looking for fuel leaks today I did find the lift pump is weeping but thats not going to cause the truck to make fuel disapear that quick.

My IDI F-450 didn't guzzle fuel back that fast but this PSD drinks diesel fast the way the PSD sucks back fuel I might be going back to a IDI and live with the lower power.

I thought a 460 gas is hard on fuel you run a PSD in a 8400lb truck its just as bad or even worse.

I think I will give up the idea of deliverying sand and gravel in small loads and just stick with the junk removal and yard clean ups a 1 ton can handle that.

When your paying 3.34 dollars for a US gallon of diesel fuel this truck is draining my wallet.

Why don't you try a different gear ratio. I'd amagine your 450 has like 4:63 right, why not try a 4:10, and use low range more often when pulling the heavier loads. If you have an auto i guess you don't have that option.

You know your truck, but I can't see you gaining that much by going from an f-450 to a 350 with the same motor. what are you gonna get 1-2mpg difference?

I can't run 4:10s in a F-450 you would have no pulling power with the 4:63s I noticed a big difference from the 5:13s my IDI had which got better fuel mileage. If I'am going back to a 350 its going to be a 4x4 but my plan is to keep the empty weight of the truck down to 7400lbs so 1000lbs lighter than what my F-450 currently weighs.

I haven't even got a dump body on the F-450 and it weighs 8400lbs it just has a 12x8 flatdeck on it. By the time I add a different dump body and hoist it will probably weigh 9000lbs.

I would be happy to get 15 mpg with a empty truck compared to the 9.5-10 mpg with a loaded truck I'am getting with the 450 and 12 mpg with a empty truck.

F 450 as daily driving to a job? Holly cow.
Why don't you get a Ranger 2.3, I-4 averaging 24-29 mpg, put Amsoil PI fuel improver, and you will average like 25-30 plus miles easily per gallon.

My friend has 94 Ranger which averaging 24-25 miles city driving per gallon, and that truck has over 155k on it.
Ranger is the perfect truck for do errands and estimate and all sort of nonesense from site to site, especially construction job, stop and go.
I hear your wallet ripped with that F-450!!!

I think my 77 F350 4x4 dump with a 460 is horrible. I get 3.4 MPG. Checked it many times over the summer. fill it up...drive 68 miles...fill it up.

I've been driving my 96 F250 stroker for years, and am at 200k miles. She runs all day on an empty load at 17MPG doing the speed limit, and about 14-15MPG with my lead foot down doing 120 everywhere I go (Love the chips and programmers).

It's only 3/4 ton but ya may want to think about it. I used this truck for about 6 years pulling a 20ft enclosed trailer with 2 full 1000liter water tanks on it, and a bunch of equipment in the construction business.

From the way the truck feels (still tight and trouble free) i'm guessing I have at least 200k more miles left on her.

Gravel Rat,
You should have bought a cummins.

weve had them all....most loaded truck for us would get between 7-12 MPG no more than that...even the I-6 cummins we had would get 12maybe 13 on a good day loaded. Only time the cummins comes into play with better milage (18ish) would be when its a 2wd srw single cab.

My 96 gets around 20mpg and it has 250,000 on it. I don't get why people think the strokes are bad on fuel milage. My brother in laws 99 gets 21-23 around town unloaded.

LOL.... right. My 4-cylinder Ford Ranger around town gets 20.5mpg.... there is no way a 7000-8000 powerstroke equipped truck is getting over 20mpg around town. It is just not possible. You guys need to start using calculators to get your fuel mileage.

Yup......my 03 f250 gets 6.5mpg trailing my enclosed 18 footer around town. Plus the best MPG I ever got (9 mpg around town, unloaded, no trailer) was 13mpg Highway, no trailer and unloaded.

FWIW...... either charge the customer accordingly, or get customer closer to home..... Gees, this ain't really that hard to figure out.......:rolleyes: :rolleyes:

Thats pretty crappy mileage for a ranger. Sorry to hear your getting the same mileage with a 4 cylinder as I am with my stroke.

You wouldn't object if I said I had a cummins though would you.

I track every tank of fuel i put in my truck. Right now I'm getting around 18mpg, I contribute it to the cold weather, the truck makes more boost in the cold so it must be supplementing it.

When I bought the truck I got 10mpg, again sorry that I actually know how to work on my vehicles and can improve them to get good mileage. :rolleyes: :rolleyes: :rolleyes:

A good tune-up and the right air pressure in your tires might help,so does a locking gas cap.(in case ya dont have one)

My fuel mileage isn't so bad then if you guys are getting worse than I'am :(

I'am paying more for fuel thou compared to what you guys are paying as I meantioned I'am paying 3.88 for a US gallon Canadian funds or 3.33 US gallon US funds.

As for a F-350 getting better fuel mileage I'am still not sure of as the engine has to work harder to pull a truck with 4:10s over my truck with 4:63s.

What I'am after is empty truck mileage as I don't get paid for using the truck to go to jobs when I'am not hauling anything. When I'am hauling I charge the truck out at 50 dollars per hour.

The reason why I like the F-450s is they can easily pack 6000lbs or more I don't carry those kind of loads all the time but when I do its nice the truck does it easily. A F-350 really struggles when you gross them past 13,000lbs where as with a F-450 you can gross them 16,000lbs or even 17,000lbs.

Well I still do not believe you get 18 mpg around town.... possibly on the highway. My Cummins 2500 does not get 18 around town and it is a much more efficient engine than a powerstroke.

And yes putting on an air filter, fuel filter exhaust, timing chip is not rocket science for improving fuel mileage, but I am glad you figured it out.:rolleyes:

And more than likely it is the fuel this time of year that hurts fuel mileage... the colder air should make your engine more efficient.

Exactly its not rocket science, so why aren't you doing something to get better fuel mileage? I've done all the little tricks to get better mileage so theres no need to call BS on me, because it does get it.

More effiecency also means more fuel is being burned. Hoter the burn the more its going to consume. more boost it makes more fuel it compensates with. They keep number 2 diesel all year round here so I doubt its fuel.

Oh btw lawnworks. Since you like to pay people to do all the work on your vehicles (IE your race truck that was built by someone else, we know we know), I could tweak your ranger to get better mileage...for a small fee of course.

LOL... yeah come on over and tweak it for me! I will enjoy a stogie and watch while you install me a new air filter... sounds like a deal!

I just got rid of my 2001 Dodge Ram 1500 last week because it was drinking gas. The 360 has alot of power but it likes gas.....6-7 mpg towing, 10 city, 12 highway, and 2-3 snowplowing. I bought a 2004 Ford F-250 SD Supercab 6.0 Powerstroke and I was getting 18-20 mpg on the highway coming home from the dealer! Just wait till it gets the chip and exhaust!:p

12 mpg out of a F-450 sound pretty good to me. I have had many trucks gas and diesel and I have never got 20 mpg out of any of them. So I really cant beleave that people are getting 20 out of a psd and 15 out of a V10. These are trucks and they are build to pull and work and yes there going to get crappy mpg and that just the reality.

The only way anyone can be getting 20 out of a PSD is on flat ground, unloaded, with a tail wind. We never got over 12 with any of them. Either that or they need to head back to math class for a refresher.....

I dont have the computer to tell me so booya! :p

Here boys and girls. 22 gal. front tank and 18.2 gal. I filled both tanks up, about a month later I went to refuel. I always check the trip odometer. It read 519 miles. I filled it up again, 70 bucks AKA 28.9 gallons. (28.937 if you want exact). Now then lets all go back to math class. 519 / 28.93=17.93 mpg AVERAGE

Thats not hauling anything, and I don't really drive it easy, I get on it now and then. That was just for December and I filled it up on the 4th of January. Don't believe me if you want, but I know what I got, thats all that matters :waving:

I've never really heard of anyone getting good mileage with a stroke until 50-60,000 miles.

I don't see whats so hard to believe, i have a f250 with 3.55 gears, leave it in 2wd, its got a tonneau cover, new exhaust (turbo back), cold air intake, chip, all fluids were changed 10,000 miles ago except oil that was 5,000 miles ago of course, dry weight on it is upper 6000's I believe, I can't remember what it was exactly when I was scrapping some stuff, I think 6900. Does it make you feel better if I tell you my mileage drops off when I get close to the 5000 mark on my oil? I am there now, 4600 miles on the oil, that could be why i'm only getting 17.9 instead of 20 :p

A month it takes you to empty both tanks ?

My truck emptys the rear tank every 3.5-4 days and I only really drive the truck a hour a day its 30 mins to work and 30 mins back. Its 32.4 miles total each day so 129.6 miles every 4 days.

The most I got out of the rear tank safely was 157 miles and it was running pretty low. I usually don't like running the fuel down to less than 1/4 of a tank. We only have one gas station in the area so you gotta make sure there is enough fuel in the tank.

I always keep some reserve in the front tank I don't use the front tank too much its developed a little leak.
