Just stating facts. A 7, 8 or 9 thousand pound truck is not not known for economy. Just because dropping cylinders barely improves mpgs on a lighter more aerodynamic yukon or suburban doesn't mean it will work on a heavy box like the SD.
The 5.4l V8 and the V10 get very close mpg despite 5.4l having 2 less cylinders and 77 ci less.
If mpg is a concern and your looking at an F-550, maybe you should look at a medium duty F-650 with a diesel, of course there are cons there as well.
The whole reason I'm looking at the gas engine is the 6.4. I will NOT buy one of those engines. The F650 would not be any better, and doesn't fit the under 7' requirement. Dropping cylinders would help while idling and running the pto. Tow trucks here see at lot of idling time in traffic, hooking up, etc. My V10 gets 6 mpg around town now. My 6.0 gets 10 mpg around town. The 6.4 gets about 8 mpg in a class 4/5 around town. I need to stay in a class 4/5 truck for weight carrying and height concerns. I guess no one has info yet on this upcoming engine. Maybe I'll have to go Dodge/Cummins this time. Not enough feedback out on those yet though. LS
exactly right on that one DKF! these trucks are made to work, not play around and see what kind of mileage we can get with this or that doodad. get real, if u want mileage, u dont buy a truck period.
You obviously have not read my posts. I have to buy trucks, they are how I make my living! Don't fault me because the cheap azz average American consumers don't understand that fuel cost has gone up. They don't want to pay more because fuel prices went up. I'm just trying to run my business as efficiently as I can, to save guys like you from complaining about the high cost of towing....
I may be unconventional in the way I think but (flame suit on) here goes. I'd take a couple of your older F-450s and F-550s and do a cummins 12V or 24V swap. (Going to get flamed big time for this one) You are not going to beat the cummins for fuel economy and overall high mileage longevity. Even with the cost of diesel you'll still come out ahead. Take the best built truck on the road (Ford SD) and put one of the best diesels on the market in it. (Cummins) and run the truck till it dies. I'm a business owner myself and honestly I can't see buying new trucks every few years, but thats just me. My old neighbor works for a trailer manuf and they have a late 80's dodge with a 12V cummins in it and a 5 spd manual reg cab dually to make trailer deliveries in the NE US states, that things still making runs and has to have at least 500k on it by now. Just a thought. Guys be gentle.
hi lloyd. here is the scoop. if i offended you, i am sorry. its just that i have been on this site for 5 years now under 2 names, and the gas mileage thing has been beat and beat and beat to death big time. always the same. i understand you run a business, and you want to get the best mileage to get the most profit margin. it would seem for towing and hauling big loads, you might want to consider some sort of diesel and get maybe 2 miles per gallon better, but spend 75 cents more per gallon to fill it. to me, there is absolutely no gain in buying a diesel anymore unless you are looking for absolute maximum towing. i get 13 mpg all day every day with my 250 v10 six speed, but i drive it unloaded. 6-8 is probably the best your gonna do with much weight in it. a V8 of any sort is not going to get any better mileage no matter what you do with it IF ITS TOWING OR HAULING. unloaded maybe. DKF might have a point. again sorry. matt
No problem Matt. Every 3-4 years I get one new truck. I'm just over 3 years since my last one (6.0), and it has 78K miles. I honestly don't want to keep it after the warranty expires. I'd love to stay with Ford, But I will not buy a 6.4 The MPG is terrible, too many problems, and they are shoehorned in there so that you can't even work on them. My V10 truck has been great, (very reliable) but fuel economy is only 6 around town. I would rather buy a V10 again, than the 6.4, as reliability is more important than fuel economy for me. My other option is the Dodge 5500 CTD. I'm really not sure I want a dodge though. I still believe Ford builds the best cab & chassis. I just don't want to order a new truck, and find out a month later that a better engine is 6 months away. I will at least wait until the 09's can be ordered. Lloyd

LSchitown.
Sounds like you would have 4.88's or 5.whatevers. Chances are that over half the time yoiu wouldn't need that short of gears. Might want to consider a Gear Venders unit. Or consider a hydrogen vapor add on.
hey ls, you cry about the mpg with your v10 but your stroker is only a couple of mpg better after a chip/progarmer, isn't your real problem a small gas tank?? did you ever own a 460 in a truck like this?? fuel costs go up& you have to charge more. v10 isn't any worse than a 8.1 chevy ,& a 5.7 dodge would'nt do the job . if you do the math now the v10& 6.0 psd have be about the same cost per mile [fuel wise] any way all our complaining isn't going to lower gas prices bseg barry

The chip does not give better MPG, just more power. My 6.0 is run on what they call a "looney tune" which is pretty much the max power setting. It gets the same mpg stock, or chipped, so why not have the power? My real problem is not a small gas tank. It's the cost per month to operate. I did own a 460 flatbed tow truck once that got 9 mpg around town. My V10 gets 6 around town. My second problem is that the new 6.4 gets worse mileage than the 6.0 which almost evens up the cost per mile to the V10 for me. It currently costs me $2500-$3000 more per year to run the 30,000 miles a year in the V10. Right now, my V10 is a back up unit for that reason. I'm looking to replace my 6.0 in the next year, which is the whole reason for my post. I won't buy a 6.4 PS. I don't like them at all. As it stands now,the 09 Ford F550 V10 will probably be my next choice. I will consider the Dodge 5500 CTD too, as they are getting somewhat better MPG than the PSD. I like the Cummins, it's the rest of the truck I'm concerned about. Lloyd
I hear the V10 is being replaced with the new Boss V8 soon. Does anyone know when exactly, and specs of the new engine? I'm looking at getting a F550 soon, and would really like to get better than the 6 MPG in town my F450 V10 gets now. Lloyd
Sounds like you have more info than anyone else , Who ever told you about the V-10's future should have all the rest of the info also No?
I head the V-10 will be around for awhile , They have no replacement for the H.D Vans and the F53 Motorhome chassis. The V-8 Boss will be a nice upgrade from the 5.4 but will not and can not replace the V-10 and all its applications
With all the Drama in the Diesel world that extends the V-10 lifecycle even longer
Ford Has stated no cyc deactivation coming but who know's
hi, my f450v10 auto 4x4 cc 9' tow body draging my 20k excavtor and trailer,around a hilly city gets more than 7.5and emty as much as 10. don't know what the truck weighs but it's heavy . lots of tools prob. 10k-12k. i have a friend that has a 550 with a 6.0 get about 2mpg more . charge more . bseg barry
hi, just a thought was your 9.5 mpg 460 a stick or auto?? we had a94' 96' 250 that had a 460 5 speed man. that got 16 mpg emty and a auto that got 9-10 mpg. anway ,see ya barry
460 was an auto, but on a 9500# f350 instead of a 11,000# F450. Also, I would change to 4.10 gears on the V10 if it drove more highway. Around town, it won't get any worse mpg with the 4.88's. LS
