Chevy 1500 4x4
Everyone I talked to that has this truck said they get average 17-18 mpg
Brand new all factory straight off the lot truck, no loads hauled
I have 3 friends with 2014 Chevy/GMC 1500 4x4 crew cabs.
Empty, no trailer, hwy driving 65-75 they are getting 19-21mpg.
Average combined they say 16-18mpg driving easy.
Just filled up, I came up with 12.9 mpg! That's better!
I also used 100% gas, so that should help also, we'll see
Now the trucks computers acting like it should, it's fluctuating up and down when I gas it or coast, before it seemed stuck, only moving one or two tenths no matter how I drove, and over long distances
