2015 Chevrolet 1500 gets poor gas mileage when towing

rated towing is 9200 lp. my trailer is5444lp. bad gas mileage

Poor gas mileage while towing a 5000 pound trailer . No surprise there .


How far are you towing? 50miles? 800 miles? Is this a route you normally drive? Unloaded? No trailer point A to B is xx mileage.
Pulling trailer on same route and mileage is what?
If you tow rarely then it might not be an issue?

What kind of trailer ?
5th wheel travel trailer ?

Define “bad gas mileage”.
Has the MPG changed in the past five years?

The EPA says a 5.3 liter with 2wd should get 17mpg combined without a trailer. https://www.fueleconomy.gov/feg/bymodel/2015_Chevrolet_Silverado.shtml What engine/drivetrain do you have and what mileage are you actually getting?

Due to the laws of physics, vehicles tend to get worse fuel economy when towing. I know, I had to sit down for a moment when I learned this secret of the universe as well.


The big decrement to towing is besides the weight, but wind resistance. 5,444lbs is a good size trailer. I suspect you gas mileage could easily drop in half or more.

The trailer weighs about as much as the truck. So doubling the weight that is being pulled could cut the gas mileage in half.

I would expect 8 to 10 MPG in that vehicle while towing that trailer.

Even on a good day I would not expect good mileage with a 2.5+ ton trailer being lugged along.

A YouTube test of a 2015 1500 with a loaded trailer showed 7.55 MPG as compared to 19 sans trailer. The dashboard display showed 8 MPG. So if you’re in the 7-8 range I’d say things are normal.


I’ve got an f150 with v8. 17mpg on the interstate at 70mph. Pulling a 16 ft v nose utility trailer weighing about 3700lbs loaded at 70mph equals 9.5 mpg.
Cutting back to 60mph on 2 lane roads gets you about 11 mpg. Wind is a big factor. Turning off the cruise control feels like you’ve deployed a parachute.
