Can you turn 4x4 off?

I have a 2014 Overland that is 4x4. I was wondering if there was a way to turn the 4x4 off and just use 4x2 to get better gas mileage? Right now I am getting 20.5 average.

Thats pretty good mpg for a WK2, even the 4x2 models. Your Overland does not operate as a 4x4 in normal mode. 4x4 gets engaged when wheel spin is detected. So typically you are driving in near 4x2, thats 4x2 plus all the rotating front end driveline pieces and a little bit of drag in the transfer case.

In order to save mpg, you need to stop all that rotating drivel line mass that adds drag.. but there is no way to do that on the WK2... nor most other of today's AWD light trucks.

Do not mistake temptation for opportunity

Not possible to "turn it off" and wouldn't really make any measurable difference if you could. Don't know what engine you have but mine has V6/2014 with 3300 miles, gets a hair over 23 mpg, so if you've got a hemi, that's darn good.

If you are in cold weather that is pretty good for either the v6 or v8. We are getting around 18 this winter, down from 21 in the summer.

If you are concerned about mileage then you bought the wrong vehicle.

Then 20.5 is really low unless you are consistantly doing stop and go driving.

Don't forget the effects of cold weather on mileage...and yes, your driving patterns and terrain are going to matter, too.

Yes the cold weather effects mileage but that is the lowest by far of anyone I have seen with a mileage report on a diesel.

How long are you letting your WK2 warm up? Is it spending alot of time at idle?

According to Fuelly.com, the V6 is averaging around 19.2 across all drivers. The diesel is about 24.7. There isn't a way to turn off 4x4 on the GC. But assuming you have a V6, you're actually doing pretty well.
