Can an 08 Ferd F-450 PowerJoke get 11 mpg towing a 41' Toyhauler 5er?

[Grizzly]

My brother-in-law, who has an 08 Ferd F350, told me this morning that a friend of his who has the same Powerjoke on a F450 gets 11 mpg towing his 41' Toyhauler with triple axles, which weighs 22K lbs. My brother-in-law also claims that he gets 21 plus empty on the highway doing 70 mph on his own Ferd. Is he lying to me or what?

 

[DCreed]

go with him, fill up the truck drive a few miles and fill it again . then calculate the miles per gallon. I bet his story changes to "uh ,well it usually... but my over head says 22mpg you musta done it wrong!"

 

[oneshotkyle]

LOL. probly the guy holding up all the traffic when you get to a passing lane. LOL. he may get 11 but not following a cummins. LOL.

Out right shady information????

I have a friend that with his '08-F350 and a 36' RV got 10 +/- to WI and back from AR. so 11 is in the park but 20 is not. Most likely in the right hand lane holding up folks at the same time. I personally follow my dealers orders and "drive it like I stole it" with my 36' RV. Always do what the dealer tells you don't you?

Just love my 6. 7 except for the fuel milage, just hope it will improve to what the old 5. 9 got while pulling.

A friend has a maxi-pad 3500 and he claims he gets 14 towing and 22 empty. I asked if he uses the console or a calculator? He uses the console, I told him if he did it by hand he would find a different story. He says the dealer says the console is correct and will not do it by hand, funny when we go somewhere together he uses the same or a gal more or less than me and I ave. 12. 5 towing. hmmmmmm Nephew has a 05 power joke and he get 9. 5--10 towing.

I think it depends on how steep the downgrade is or how fast the tailwind might be.

 

[DCreed]

or how much manure the driver can shovel out of his mouth befor a trip!

If I went with my overhead, I'd claim 27 empty, driving it like a stole it. That's with edge products up on kill 99% of the time (when not raining/snowing). In reality, 24 hand calc at 60. Dead nutz on 2mpg less for every 5mph faster on the highway. at 85 all the way across S. Dakota I got a about 14. 5 I bet I average 19-20 with a 50/50 mix of city highway.



With the smarty, it's around 22 on the displacy. 50hp less I have yet to hand calc anything. with just the Smarty

I had a 03 ferd F-250 crewcab 2x4 with a P. O. S. 6. 0 eng. Once driving 60-65 MPH empty, on a 200 mi. round-trip on flat terrain, I hand calc. 24. 2 MPG.

Towing my 31 ft. Airstream (9000 lbs. wet) I averaged 11-13. 5 MPG at the same speed going cross-country.

With my Cummins, I get about the same towing but about 2 MPG less empty.

Their wt. was about the same,but it was 2 whl. drive verses 4 whl. drive.

I do all my calcs. with fuel to top of filler neck and pencil.

 

[Grizzly]

Best I can do towing our 27' Fox 5er is 11. 5 hand calc. So, anyone claiming the same mileage towing a 41' Toyhauler, weighing 22K has got to be lying, I don't care if it's a powerjoke, d-max or a Cummins.

My Dad has an '08 F-550 that weighs 10,200lbs with a zf-6 and 4. 88 gears. Running empty it gets about 11-12 mpg and with a trailer(17K) it gets 10-11 mpg. The worst it got was 9mpg w/ a headwind. The mileage stays pretty much the same, but I guess that is because of the 4. 88s. Definately not a truck to be driving around empty.

With 4. 88's what is he running on the highway maybe 60?? The engine is screaming.



I have met many drivers with new 450's, 350's, and even 250's (all 6. 4 08's), and none have been thrilled with there purchases. And the most common thing I have heard is "the fuel mileage is killing me" and "getting tired of the check engine light". There is no way anyone is getting 11 pulling a 41 ft toyhauler and no way 21 empty. Maybe downhill with a tailwind:-laf.

:-laf My Work truck has the 6. 0 w/ 5sp auto (Tourqeshift?) and 4. 88 rear. At 70 she's turning about 2800rpm, more than Im used to in the pickup, but considering the 3400 peak HP and full throttle shifts as high as 3800 or 3900, its not that many r's after all.



Weighs about 15k, overall avg is about 9. 5-10mpg. Country roads at 55-60 is best, worst milage on freeway trips.



#ad






Pickup w/ camper= about the same weight, pokes bigger hole in air, similar HP/TQ numbers, similar eng. size. 15-16 mpg driving hard. ~2100 @70mph. Apples to oranges though... . "Flat tourque curve" I-6 vs. EPA raped V8.

Now my brother-in-law has changed his tune when I told him I started a new thread on his friend's fantastic fuel mileage on his 6. 4 PowerJoke. Now he says that his friend is getting 7 mpg pulling his 41', 22K toyhauler driving Texas Interstates at 70/75 mph. I told him I still don't believe it, not at that speed.

Here's what I've been told over the campfire... 19 mpg with a ford 460 towing a fifthwheel:-laf. 16 mpg with a v6 ford ranger. . empty(probably true)So pick a number try to keep a straight face

Here's what I've been told over the campfire... 19 mpg with a ford 460 towing a fifthwheel:-laf. )

I had an F-150 2WD company truck with the 5. 4 and it got about 10 MPG pulling my 14' cargo/MC trailer. 19 with a 460? Was there some wacky-weed burning in that campfire?

I drive an '08 F550 for a neighbor every now and then. The 36' livestock trailer doesn't have near the wind resistance that a 5'er does, but it weighs a heckuva lot more than 22K. Yesterday I ran 150 miles one way empty trailer, console said 8. 6mpg. By the time I got back home the console said 7. 5. Majority of the miles were spent between 65 and 70 mph. My truck at that speed with that kind of a load will get around 9mpg.

Imagine that!! I know of 2 people with '08 6. 4's, both of them said they were getting around 8 around town. Just saw one of them tonite and at 13k miles he is thinking of stuffing a Cummins in the thing already, can't get out of its way , let alone when he is towing something. The other guy just went on a round trip to Oklahoma and back with his 39' triple slide 5 'er, have to see what he did on the trip.

:-laf Only if it's being towed by a CTDOo.

I took a 6. 4 for a test drive. . that motor is LOUD at idle. Didn't get outa it's own way kinda feeling as well.
