I just traded up to a 2012 manual 6 speed. I don't even have my 5100s or tires on here yet, they're sitting in South Dacotah waiting for me to install in two weeks but now I'm rethinking that. So, bone stock and brand new:
Three fill ups on highway
13.62 mpg (gave it a little first day)
First fill up after running through almost a whole tank in town
My 2011 automatic was averaging 18.4-18.6 with most in town.
I drive light, I've had manuals most of my life (minus two vehicles)
Could it be break in? Winter gas?
I thought it was bad with the v6, 6-speed guys reporting 13-14 avg but figured they didn't drive as nice as me!
I'm literally thinking about trading back in for something else!!
Man I love driving manual but at the cost of 4-5mpg vs my automatic, not worth it!
Anyone else running this bloody low? Can i expect improvements. Or should I keep my after market tires, wheels and suspension and get a truck that doesn't inhale gas?
