Towing MPG

[Norquist]

Well I got it figured out, and a little suprised at the numbers. Their lower than I expected but, that could be due to the constant down shifting that it does :confused: I was really thinking I'd get closer to 13 to 15.

Towed loaded 25'toy hauler approximately 8,500 lbs. from LaMoure (South Eastern) North Dakota to Montgomery, Alambama total of 3,439 miles used 350 gallons of fuel for an average of 9.81 MPG. Tried keeping it at 70 - 75 MPH where permissable.

Best I saw was 11.5 MPG and worst was 7.9 MPG

Hopefully the dealer can get the down shifting situation fixed next week and check all again with better MPG.

Sound about right or what :confused:

That is what I am getting too.

I did the tranny reset last night for towing the trailer this weekend, want to see if that makes a difference...?

By tranny reset, you mean the 55mph slip into 1st? ~ odoh

[AlaskaDmax]

Yes, Sir. That is what I mean! :D

I'm getting between 9-11 mpg towing a 24' enclosed weighing about the same. I've got the ZF-6.

9-10mpg at 75mph, 10-11 at 65mph

I think it's wind load based more than weight based.

My millage has been 11-12 consistently towing 1 car and accessories and 10-11 with 2 cars. Both in the same trailer and both at 80+ speeds. If the speed is dropped even 5mph to say 75 the millage goes to 9 because of the constant downshifting.

And yes I have all of the updates.

Last weekend I pulled my boat to Lake Havasu and got between 15-16 MPG at 75 MPH. My boat and trailer weigh about 4500 lbs. I just did the identical trip yesterday without towing anything and got 19 MPG at 75 MPH. I have found that the more miles my truck has on it the better MPG's it is getting. The first time I took that trip towing my boat I got 13.8 MPG's. My truck now has 13,000 trouble-free miles and I am loving every one of them.

So ya really can drive 55 mph and slip the tranny into 1st?? Sounds awfully scary to me :confused: Let us know if it helped.
