MPG. What you did and whats the best?

TRD offroad access cab v6 automatic stock truck no offroad goodies except a set of rock sliders.
Commute 14 miles a day split equally street and highway. some freeway on the weekends. Last 8 tank fulls 18 mpg. maybe varies a little between 17 to 19 depending where I go on a daily. No long trips for me. My truck has yet to see 20 mpg. I don't drive it hard. I hope to get a little uptick when the tranny is flashed.

 

Doesn't anyone divide the gallons to fill into the miles on the trip odometer (set to 0 at last fill up)?
I trust the onboard computer and estimated mileage figures it gives as much as I can throw it!

I know this is a 2016+ thread, but those who do real math and honest testing are not reporting much differently than my average MPG in a 2010 DC Automatic V-6 4WD: 15 in town, 16 mixed, 17 highway, 18 if I am lucky, 19 if using non-ethanol Mexican gas, 20 only a couple times on long trips with no load, and no speeding.

 

Second Fuelly fillup. Doing pretty good considering the amount of times I'm idling and my commute home has quite a verticle climb. I have a pretty tame foot and don't really get on it unless I need to. Still pretty impressed. My last "Truck" was a BMW SUV with a 2.5L Str6 and it always averaged out to 20MPG. But then it only had an Auto 5 speed.

*Note* I just started to use Fuelly. Any reason the Badge doesn't update? If you click it you will see both fill ups.
