Post your fuel economy while towing

Recommended Posts

I have a 2014 6.2 with 3.73 gear 4x4 Crew 6ft bed. I pull a 3500lb trailer between 70mph and 75mph and get 12-14 mpg average. Probably closer to 11-12 when going 75. A bit higher when going 65-70mph.

2015 Chevy 2500 HD Crew Cab 4 x 4 My experience;
Here is my experience with towing my 33ft Travel Trailer (9500 lbs) with this truck. It tows easily at whatever speed you set the cruise at, what I never thought thru was where the torque band is on this truck. It will select whatever gear is needed to pull the load, this sometimes results in driving in third gear up hills at 4200 rpm. It rarely would shift up into 6th gear and would not stay there long even on the slightest uphill. This all resulted in an average MPG of 6.9 on my 1300 mile trip to Florida. Encountering a strong headwind coming home it would still pull no problem at 66 mph but it got 5.8 mpg into the wind. Around town it gets 11.6 MPG driving very easy. disappointed by MPG.
What was your MPG towing your trailer?

Towing a 25' 8700lb (when loaded) 5th wheel with a 2012 2500HD Sierra extend cab long bed SLE 6.0L. On average 7mpg while towing.

It would be nice if GM made the 6.0L run on 4 cylinders when it doesn't need all of it ponies. My gets about 10-11 around town. So not much has changed in the last couple of years as far as fuel mileage. Of course that is because the FEDs have not man dated any improvements in HD trucks yet. It is coming tho. I just read an article where a semi has been developed that will get 12mpg pulling a full load. I do not need more horse power just better mpg. My Ford Fusion averages 35.8 mpg with a 1.7L turbo. and it has plenty of get up and go. So maybe a smaller turbo engine would be better in the HDs.

1996 4x4

5 liter

nv3500

3.73

oil cooler, functioning factory bypass with billet filter (I would not have bothered without that factory relief working).

 

Towing a 1987 subaru, car dolly. Advice to keep it out of overdrive, had to stay at car dolly limit of 55 anyway.

36 miles highway, 16 miles back road. 22mpg.

 

it is nearly the same loaded or empty. I bought it in january, have not seen spring weather yet.

a recent 60F day has it in the middle 20s mpg. Lugging like a tractor trailer @ 2100 = 72mph.

 

I also found the tranny shaft is 84mm. Not exactly small is it. Not sure who or what makes a wimp of those..but they must be mentally challenged with gear fluid of the wrong kind. I'd tug at a kenworth with it...factory gm fluid.

2014 Double Cab 4.3 EcoTec 3.23 gears all stock. I get 13.2 while towing my 23' bay boat at 60-65mph and 10.8 to 11.2 if I go faster. I wish it had 3.73 to 4.11 gears to keep the RPM's up. I have to lock it in 4th gear to stop the gear hunting on hilly ground. I still wish I had the 5.3 at times.

Typically average 11 mpg pulling various campers with 2010 GMC 2500 6.6 diesel. Winter economy is worse. Summer better. Last few trips over 12 mpg. My dually does about 1.5 mpg worse.

Those Grey Wolf's are easy pulling trailers. Move a lot of them.
