When I tow my 24' enclosed car trailer with my 3v V10 and 4.10 gears, my mileage drops below 10 mpg. I say calculate the total fuel cost of diesel @ 15 mpg vs gas @ 10 mpg for the anticipated miles as a starting point.

 

I talked to the fella who wants me to get the car and, he was fully anticipating buying the car, but the guy who owns it just up and quit talking to him lol. Theres still a pretty good chance Ill be going and getting a car for him, just not this one.

With mileage at 15 on diesel vs 10 on gas: its close enough to not matter which one I take lol. Diesel has actually started dropping here (finally) so its a better comparison.

 

Amen to that!! Also, never understood why they have such a high reverse gear either. That same heavy **** load I pull forward in low gear is the same load I gotta back up(manuals). Not to mention having to steer goin bakards!


I have a 20' car hauler(open) and loaded with a vehicle I get 10-12 avg mpg hwy at 70mph. Towing my bullnose extra tall enclosed trailer I get 9-10mpg at 70 hwy. That thing is a sailboat mast off a pirate ship. Steals the loot outta my wallet for gas money!

 

What transmission do you have? Reverse on my 6 speed is almost identical to low/1st.

 

If its an auto, itd be a 4R100. 5R110 didn't come out til '05.


So you have the ZF6? That pretty awesome! Thatd be a towing machine

 

Would you be towing an open or enclosed car trailer? J have a 1999 F350 Super Cab DRW with a V10, 5 speed manual, and 3.73s, using 235/85R16 tires. Empty my best freeway mileage has been 15, but when I hook up my 24 foot Wells Cargo enclosed race car trailer, it drops to about 9 MPG. With the 3.73s, I rarely use 5th gear, as when I tried it in the past, it had zero throttle response, so I normally tow in 4th gear, cruising about 2600 RPM. My trailer fully loaded weighs around 7500 lbs, between the weight and decidedly un aerodynamic trailer, I would have to think that an open trailer would be much less affected by air drag. I had considered switching the rearend to 4.10s or 4.30s, so O/D would be more usable when towing, but since the truck only sees a few thousand miles per year as my local dragstrip is only 45 minutes from home, it simply wasn`t worth the expense.

 

Not necessarily speaking of this truck, but some that I have owned in the past. One in particular was a 2004 F150 5 speed manual. It had a nice 1st gear to pull forward, but reverse was like a 2nd or 3rd gear ratio. Backing a heavy load was either a point and go with lots of praying, or slip the clutch tills it boils off. The only truck that I owned that had a manual tranny with a low reverse was a 1976 F250 with the granny 4 speed. Loved the truck, hated the 351 mod. engine.

 

I have a 2010 F350 V10 6speed manual. Last week my highway mileage was averaging 9-10MPG towing my 18' enclosed car trailer with Kubota B3800 HST tractor/loader inside up and down I-95 at 70MPH 5th gear on cruise. Without a trailer my truck averages 13-15MPG, depending on traffic. It seems to me, considering diesel is still close to $1.00 more per gallon, a V10 averaging 10MPG is probably slightly more economical than a diesel averaging 15MPG.

 

Itd depend how far you were traveling. At 1000 miles, itd be near identical lol

 

My '04 dually with the V-10 gets 8.5 mpg consistently the way it is setup in the pic. ( 2000 lb. slide in and a 7500 lb. trailer)

4.10 rear and the overdrive is not used.

When I first got the truck, it got 9.5 empty with the overdrive engaged.

 

'06 E-350 w/Quigley 4x4 (about 7,000 lbs curb weight) towed U-haul car hauler (2,400 lbs?) with '74 Pontiac (4,300-4,400 lbs) 1,700 miles from New Mexico to Rochester, NY and averaged just about 10 mpg. Speed limit plus 5-6 mph, most times.
