What kinda of MPG is you 05 V10 getting?? - Diesel Forum

SteveNC · 03-05-2005, 07:12 AM

I'm looking at one of these trucks for my daily driver, which is only about 10 miles to work. Would be getting 4wd crewcab auto. Anyone out there have any mpg number for city and highway.

Also, it will be used to pull camper couple times of year.

Thanks

I love mine (see signature) Your choices are 4.10: or 4.30 rear ends. Both have great towing power.I own a few other V10s (small business) with both options and the mpg difference is not large. (about .5mpg)

My truck is just getting broke in. My mixed city/hwy 16mile each way daily commute is averaging about 11.4mpg. Best is 12.2mpg so far and towing heavy (mostly interstate) is about 10.2mpg.

I am a lead foot, mostly rabbit starts empty, I tend to haul my 22,850lbs loaded total CGVW at 70-75mph.

The best I have heard on these boards for the empty 3valve V10 auto is in the 14mpg range but typical seems to be 11.5-12.5mpg.

That doesnt sound too bad! I'm also looking at GMC SLE 2500HD with the 8.1 Allison in it. Both trucks are priced about the same.

Does the short trips hurt the V10 like it does the diesel? I'm sure it's not good for any type engine.

I owned a 7.3 PSD and then two V10s for my personal trucks. In a small businss my partners and I own two 6.0L PSD, 8 2 valve V10s and a E450 cargo van...yep V10... we are pleased with the economy, reliability and capabilities of every truck.

I livew in Texas so very cold morinings are real but not as low temp as up north.

The Diesel requiers a wait to start for the glow plugs but you get used to it... biggest probelm converting from gas to diesel is the wait to cool down after spinning the turbo hard.. lots of folks forget that and cook the oil as the very hot turbo has oil bath bearings.

The V10 powered trucks can be operated exactly as you use your car... quick start, and instant shut down. no problems.

Caution... I liked the soft cushy ride of the HD2500 a lot but the 8.1L and Allison is a gas pig! And ours used a lot of oil between changes. If you want a non work truck it is just ok... not very impressive at all. I did not start out as a 50 year old Ford snob.. but since 1999 to present have come to realize that the Ford trucks are beter built, great power, realtivly easier on fuel and tend to have slightly beter reliability.

The GM trucks are all soft sprung and very comfortable but don't hold up well to being worked hard and put away wet.

I assure you either the PSD or new 3 valve V10 will exceed your every expectation.

You average 10.2 at 75mph with 23K lbs combined? That is better mileage than my diesel gets under similar circumstances. [img]/ubbthreads/images/graemlins/frown.gif[/img]

OH no sir... BobR Sorry the sentence was worded badly... running empty and hot on a 75mph rated road so I set cruise to 84 most of the time... this 3 valve V10 got extraordinary mileage 10.2mpg over all for a recent fast trip out to Tucson and back. When I wrote that, I was managing two different threads one here and one at the FTE site. Should have proofed what I wrote.

Any way good catch!

I do not get 10.2mpg towing the heavy 22,850 GCVW for the whole trip. But in my note book I have fillups that indicate 10.2 for a particular leg. In this case part of the down hill side back to El Paso from Lordsburg New Mexico and I admit the wind was in my favor that morning. With the very heavy load she got 9.7mpg. This is the trip averages for the entire 1600 miles.

My on board computer has been checked against manual math every 3rd month since new and is .2mpg high each time so I consider it accurate enough. There are parts of the track west bound climbing the hills and mountains that she drops to 7.7mpg... and on the trip back east bound she can get over 11mpg with the load on. If you understand Interstate 10 from Tucson to San Antonio or vice versa and how the elevation changes are long and gradual over all, then you see the effect of a round trip.

When we recently traveled from Central Texas up to Vail up I25 and west on I70 the Loveland pass east of Golden Colorado at over 11,800 feet would have me reporting only 6.4mpg just to get there. However I choose to include the return portion as part of the WHOLE picture. On that trip with the new truck I got 9.4 mpg average. Additionally this V10 and torqueshift and 4.30:1 gears did not bog down and require extraordinary high rpms to climb the mountain. My 2001 F250 2 valve V10, 4R100 and 3.73:1 gears really struggled on that leg of the trip two years ago and required me to run the rpms over 5000 for longer than I was comfortable with. The 05 handled this MUCH better!

The significance here is my 01 2valve 310 HP truck with exact same loads and same trips dropped a lot more between empty and heavy. Daily mixed empty driving eventually averaged 13.7-14.4mpg but towing similar loads she was typically between 5.9mpg and 8.2mpg. As you can see a very significant difference in the spread.

My 05 does not get as high a daily average, currently 12.4mpg, but when we trailer, she does not drop as much, evens out in my estimation over time and my family and I are quite pleased with the towing performance of the 3valve V10 & Torqueshift combo.

That is impressive. That's probably 40% better than my old 460 would get under similar circumstances.

Man. 9.7 @ 23K is pretty darned good. Crap, at this point, I guess that all that I have to fall back on is that I like towing with a diesel because I find it more relaxing to be able to run lower rpm. Sounds like most everything else is a wash these days.

I'm not sure how much $$$ lower rpm towing is worth!?!?! [img]/ubbthreads/images/graemlins/shrug.gif[/img]

I am getting almost 6 MPG towing. My toyhauler is probably 11,000 pounds. My normal trip is all mountains. Most of the large grades are 6%. Daily driving mixed is showing 10 to 11 mpg. Only a tick over 3000 miles so she is still tight.

That sounds more like it. I occasionally drive a 2005 F450 with the V-10 coupled with the Torqueshift. It's fuel economy is fairly unimpressive to me. It's got the 4.88 gears, but I keep it at about 2400 rpm on the freeway. Payload is about 3000 lbs of tools. It get's 7.5 MPG, even if I completely BABY it. That's pretty horrible as far as I'm concerned. My dad's 2001 8.1 liter Chevy dually gasser gets 10 pulling a 12' Lance Camper with a boat behind it. Hmmm...

I can say this though, the 2005 V10 sure is a SMOOTH running engine. I really like it. I just think it's fuel economy isn't so great. Just my opinion.

yeah, i see a v10 getting better fuel mileage then a psd with a load. not even down hill with a tail wind. a diesel is a more effient engine then a gasser, i get 12mpg around town driving empty and i drive it like i stole it please stop i havn't seen a v10 get better then 8 mpg with a load [img]/ubbthreads/images/graemlins/rolleyes.gif[/img]

You can't seriously post a message like that with the truck and signature you have and expect any one to think you have a clue what a new 2005 3 valve V10 with torque-shift can do. And your low 12mpg might have more to do with all your mods and less to do with a rational comparison of stock PSD motors vs. the new Ford V10 motor.

Please note that the original post asked specifically about the 2005 3 valve V10 powered superduty truck.... you oil burners are more than welcome down here but if you don't know anything about the question and equipment asked about how about sticking to what you do know.... in this case not much.

funny out of 1000+ views and only 11 replies you would think some of you could post some compelling argument about why that inquisitive fellow might be better off with a PSD... I did in the third or fourth post......hummmm

"Diesel fuel has a higher energy density than gasoline. One gallon of diesel contains approximately 147,000 BTUs of energy, while a gallon of gasoline only has 125,000 BTUs. This means that it takes more gasoline to equal the power output of diesel, making diesel engines more efficient per gallon of fuel burned. Also, because diesel engines use the more efficient direct fuel injection method (fuel injected directly into cylinder) compared to the port fuel injection setup used in gas engines where gas is mixed with incoming air in the intake manifold, the diesel system has very little wasted, or unburned fuel. Diesels also use about 1/3 as much fuel at idle as gasoline units. Even though there are no official EPA mileage figures for 3/4-ton and bigger trucks, we've seen diesels get 6-8 more mpg than similar weight gas pickups. Over the life of the truck, this advantage could be significant, especially if you drive a lot of miles."

is this the information you are looking for.
diesel fuel is 17% more efficient.
he is based in NC so winter is not a factor.
diesel fuel is general cheaper then gas not always but on an average.
life cycle of a diesel is 300,000 miles when compared to a gas that is 125,000 ( i know some do better but if you tow the gas won't last ) but this really isn't a factor either as he only drive 10 miles a day

LATIGO1 · 03-21-2005, 11:55 PM

I get 18 mpg in town(4.10's) and about 16 mpg goining 75-80 mph on the hwy. The economy begins to suffer when running constantly above 2000 rpm. The worst I have done towing is about 12 mpg. That is on the I-?? going 75-80 with about 11-12k lbs and a lot of front surface area. So it is probably a little better on fuel than the v-10. If you only drive a few miles a day though I would get the gas. By the time your diesel warmed up to operating temp you will be shut'n her down again and would not get to enjoy it. On the other hand, the gas burner is kinda like buying the Harley but with a suzuki engine. Just ain't the same.

curinb · 03-22-2005, 02:07 AM

i'm not trying to break into the gas diesel argument but my 6.9 got 18mpg with or without a load and roughly 16mpg city thanks to the constant stop and go. and i consider a load to at minimum double the overall wheight of the vehicle. so 10k pounds is what i start calling a load. i pulled a bimmer up to raliegh and it didn't affect my mileage at all, even in the city, and steve should have an idea of what just getting into raliegh is like. but i don't drive the gassers so i can't be of much help. but if your in the city i would recomend an automatic. they suck on the highways but save $$$ like hell in the city. they save shifting time and cut fuel waste while accelerating. also the rear differential is a big enconomy determiner. the more shaft rotations to every tire rotation the less distance acomplished but the more torgue acomplished. these are two important things people seem to forget in buying a vehicle and comparing mpg. i have heard 6.9's range from 22mpg to 8mpg all based on age and trannny but most importantly the rear diferential. although overdrive is nice [img]/ubbthreads/images/graemlins/grin.gif[/img] .
