We let ours warm up before driving for ~10 minutes. After that the truck is babied and lately we CAN NOT squeeze better than 14.4 MPG out of her. This is a true calculation by dividing the number of miles on the tripometer by the number of gallons to fill the tank (until it is visibly full, yes as in spending an extra three minutes clicking the pump on and off until gas comes out). I know that's stupid, ok.
This is nothing more than a fact. My 2011 sr5 will get 22mpg ONLY if I am cruising on the highway at 55mph. Myself and everyone else around here drives 70-75mph on the highway. This very reasonable speed yields about 18mpg only for the straight highway cruise. I see no way in hell that somebody can average 19+ mpg on a tank even using hypermiling techniques, unless they drive no faster than say, 60mph for 300 miles or so, on one tank.
This truck gets terrible fuel economy. TERRIBLE! The sticker is not true as there is no way ANYBODY can obtain 22mpg on the highway cruising at 70mph on the highway. IMPOSSIBLE! With that said, I do love the truck, have no regrets, and it's freaking amazing in the snow.
Thanks
Tracked with gas cubby on my iphone.
BTW, stop idling your vehicle so damn long (getting in and driving gingerly is the best way to warm it up) and stop filling the neck up with gas. Most modern vehicles have an evap line that leads to the charcoal canister and filling the filler neck up can dump fuel down that line to the charcoal canister and you get a lovely evap fault code and a $700 bill to replace the charcoal canister.
