I am getting absolutely dismal mileage - like 280miles a tank at most.
I just recently got to the 270-280 mark on my 2011 V6 4x4 and I'm ecstatic. I ended up doing the following to get there.
1. SeaFoam via brake booster line. It threw a code about the engine misfiring. After the can was gone, I cleared the code with a scanner I have and it never came back.
2. Berrymans B12 in the gas tank and then filled up. Used the full can.
3. Used a can of SeaFoam spray on the throttle body. Didn't move it, just sprayed it while the truck was on. Took a few tries to get the engine to stay on with the air box off and everything disconnected. It actually removed some of the black stuff around the rim of the butterfly (if that's what it's called) so that more air could go through at idle.
I went from about 240-250 mpg to 270-280 depending on how long I drive on it when the truck is screaming at me 'Low Fuel'
Haven't changed the plugs either which I'll do eventually.
With that said, some may say the above is snake oil, but it worked for me.
