Can someone give me some nubers of what the gas milage would in a F250 with these two motors I am debating wich one I should get but wanted to check gas mileage. Also cna each engine tow about the same weight. I am looking at hauling a T250 Bobcat around time to time so I think the V10 is the way to go but please add your thoughts. Tanks for all input.

 

The 5.4 will get better mileage in daily driving, but when towing the 6.8 should get better mileage and will tow a LOT nicer. Have you considered a diesel?

 

For all practicality the milage between the two should be pretty similar empty. The V-10 is only a couple hundred bucks more than the 5.4, as opposed to the diesel's several thousand. Unless you are planning on towing everyday the diesel will take a long time to justify itself.

 

I haven't heard much about the 5.4L in SD, but I expect it to get about the same as the V10 unloaded with the V10 getting better while towing. The V10 is rated for more weight, between 400 and 3300 pounds, depending on configuration. IMHO, the V10 is a no brainer in the SD with it being a $600 option. No way aftermarket couple touch 90 lb-ft or torque for $600! I don't know about the diesel, though. It's a large preium up front, fuel prices are higher for most of the country, and ultra low sulfer diesel is cutting the mpg.

 

Yeah, ULSD is a big negative. I have a friend with a 2000 Excursion with a 7.3 PSD, and he used to get 26 MPG on the highway unloaded with the old fuel - true, he does have a bunch of Hypermax stuff on it. With ULSD I doubt he gets much over 20.

The V10 is pretty thirsty though - I doubt it will get as good mileage as a 5.4 with no load. Towing though, it should do better than a 5.4 as I already said, sorry to repeat myself.

 

my f150 5.4L w/3.55 got 15ish unloaded and about 9 towing. The 250 w/ 4.30s gets 12-13 unloaded and 10 towing....if you do a V10 get at least 4.10s...my dad tried 3.73 and lost mileage loaded and unloaded...he went back to 4.30s.

 

While I highly doubt the 26 mpg with a 7.3L - even with a tailwind headed downhill, I will agree the ULSD and the regen mode that GM and Ford have that injects diesel into the DPF has really tanked fuel economy of diesel trucks. I have driven many many miles in Powerstroke smokers since 1999, and the 7.3L's always had the upper hand in fuel economy (of the Strokes). I Hypermaxed my 2002 7.3L and was pleasantly pleased with the 21mpg figures and an ocassional 23mpg, and I wish there was something to do to a 6.0L to recover the poor economy. I get 16mpg stock with my 2007 6.0L, but I am an easy driver and do alot of open road driving.

As for the 6.8L, I am seriously considering one if I stay with an F-250 in spring. Otherwise, I'll drop down to a 5.4L in an F-150. I'd never consider the 5.4L in an F-250, unless it was a regular cab daily driver, or a regular cab plow truck. I know alot of municipalities that swear by the 5.4L and the 6.8L for their work trucks, and agree the diesels cost more in the long run. Then again, they don't run the mileage a year I do. If you tow and are hip on getting a gasser, skip the 5.4L. You won't regret it a bit. The fuel economy of the 6.8L and the $600 MSRP won't hurt as bad as the 5.4L the first time you hink you are going to move something substantial. And, the 6.8L will work alot less in most conditions, which will show you no fuel loss in the long run. My 2003 Excursion had a V-10 and we consistently pulled high 15's and low 16's on our highway trips down to Pigeon Forge. That was a family of four with the A/C on. It was the winter idling and around town of 10-11mpg that killed. You'll relearn driving habits and remember not to leave a V-10 idle long, but find it an extreme smooooth pleasure to drive. Good Luck!

 

The main reasons I have been leaning toward a gasser is less maintenance and I know quite a bit about gas motors in general so I can do most repairs myself if something happens. Diesels on the other hand I have no knowledge about. Gas prices really mean nothing to me anymore yeah it sucks 3.00 a gallon for gas and 3.35 a gallon for diesel. but we demand it and they take their checks to the bank. Thanks for all input please add more if anyone has some.

This "diesel=more maintenance" myth still cracks me up. I log somewhere between 50-60,000 miles a year and have been driving diesels since 1999. I have yet to see this "more maintenance". I used to change oil every 3,500 - even in my diesels, but now have bumped it up to 5,000 miles otherwise I'd be changing oil every other week. Yes, 15 quarts cost more, but the new diesels are scheduled for oil changes at 7,500 miles to 10,000. So, there are a few fuel filters with diesels, too, but they are simple to change, and they cost peanuts. Tires, shocks, brakes, etc are common to gassers as well. I have yet to replace any of them before I trade at 50,000. If you drive a truck more than 60,000, you can expect more maintenance regardless of what type of mill is under the hood. MHO.

 

i have an f150 and also an f250. The f250 is a 2001 crew cab 4x4 superduty lariet, off road package, powerstroke diesel v8 7.3L with a racing chip. For towing wise i get about 17 mpg (as low as it will go) and about 22-24 on the highway, and let me tell you, i can pull a house if i wanted too. Theres not alot of maintance to the diesels. just the normal oil changes etc.

 

Hey smoke you have a 6.0 stroker in that truck right. What year is it and have yoe had any problems with it and how does it tow and everything. deisel might be the way to go for me. Thanks

 

Yes, I do have a 6.0L in my current rig, a 2007. I have been lucky, I guess, and I hate to jinx myself, but I have had three 7.3L's, and four 6.0L's - all which have been flawless. My 2004 6.0L had a minor EGR issue, but not a big deal. This current 6.0L is tuned by Innovative Diesel and runs like a raped ape, although I strictly tuned it for turbo lag and economy. It sure is fun to drive and will fold up most ricers (and many other things) in pretty little packages like they were pedal cars. As for towing, the power is endless and seamless. The five speed tranny does downshift on some hills, but not like it's a big deal. I absolutely love Strokes, except the ride of my current 250 is rough like a cob, and for a daily driver it is getting old. I average 50-60k miles a year, so my butt knows it. I am considering trying an F-150 Supercrew again in spring for my daily driver, and have been beating the death out of whether or not the 5.4L will disappoint me towing my 6000# travel trailer. The problem is that I will never be satisfied as the grass is always greener. If I towed more than 10-12 weekends a year, I'd undoubtedly curse anything but a smoker, but most current 1/2 tons are no slouches. Good luck. I'd never bat an eye at a 6.0L. I read all the hype about it's bad release and how Ford never got it right and say "Bull". I've logged enough miles on them to know, and most - most - come to forums to gripe because their old lady's are sick of listening to them gripe. Do your research on what you buy if it's used, and from what I hear. the new 6.4L is great. They all have a few issues - Ford, GM, Dodge - but all in all, the mileage is the worst part.

 

With diesel prices $0.50 more per gal than reg unleaded I figure a diesel will have to getat lease 2 or 3 mpg MORE than I get with the 5.4L... day in and day out.

Unloaded daily driving I get 16 mpg on the nose. I have a friend who gets 18 with a Dodge Cummins. The economy is about even... or slightly worse for the Dodge.

Towing is way different. He tows a 31 foot 5er with two slides and the best he gets is 14. I tow a 27 foot TT with one small slide. The best I get is 12. Economy is same or worse for the Dodge but he pulls almost twice as much weight as I do.

So, unless I feel a burning desire to tow something a LOT bigger than what I do now, I think the economics points to what I have now.

 

at work I tow a t300 bobcat with forks, a blade, and a bucket all on a big 26 ft trailer behind a 2001 f250 5.4 and it does great. My longest trip is about 30 miles and as long as the trailer has brakes, It is a pretty easy tow. The truck has 189,000 miles and no problems(except for the IAC recently going out). I have no idea what kind of mpg it gets. Does anyone know if the f250 5.4 is identical to a f150 5.4? I would think the tune would be different?
