I really don't know if this is a stupid question or not but does 4wd burn more gas than 2wd? I really didn't notice any difference in gas consumption when I used 4wd in the winter compared to 2wd when the roads didn't have snow on them.

Thanks

 

Probably not a noticeable amount of difference between the two. You're still pushing the same weight of the truck. Your habits will probably be more of a factor than the 4wd... such as starting the truck to warm it up, etc.

 

Edited because i'm dumb.

 

i got a little different gas mileage but i was also using lower gears in 4x4 since i was off roading or flooring it because i was in mud but i have never really tried it but it seems like it is easy to get up and go in 2wd instead of 4wd seems like there is less resistance

 

4x4 will use more fuel because you are not only turning the rear axle, but also the front. More parts to turn=more load on the motor.

It is not a great amount more, but it is more.

When in 2wd your only turning the rear, and the front just rolls along.

 

in an official press release
Chrysler engineering has admitted that their old 4x4 front axle design ( called CAD )
unnecessarily hurts Highway MPG by 1

the additional 400 lbs of weight for 4x4 drivetrain gear
probably hurts all around MPG by another 4% or so

 

on a 4wd truck, the front axle is always turning anyway. it's attached to the wheels, so when the wheels turn, so does the axle. the separation happens at the transfer case. and the input into the transfer case is always turning as well. this way the rear and front are almost always in sync. that's why you can shift on the fly. you should see pretty much no difference in MPG in 2wd and 4wd
