I will be 100% honest....after reading about people getting over 20 mpg with their truck, I thought it was complete and utter BS....but I have to admit, I am now in that club. I had no idea that it was possible but.....I am running 130 miles a day like I said and have been checking my mileage the last few weeks.....here are some of my averages, most with 2-300 miles between fill ups.....20.95, 19.818, 19.02, 19.41, 20.34, 20.41, 20.82 (calculated manually of course cuz I dont have the mpg readout on my truck).....I couldnt believe it and had to tell someone about cuz I am so darn happy!!! I might drop the grill guard I got on and see how that helps....

 

That's good mileage, I'm guessing it's all/mostly highway at 55 mph or faster.

 

Yea, its mostly 2 lane road actually....I lock it in at 56-57ish so the cops dont bug me and I am good to go....I just couldnt believe it when I checked it.

 

Yea that must be nice, the best I've gotten is 18.6 but at least half my miles are city.

 

can anyone else confirm this for the fuel tank size on the 1500.

1) 26 gallon tank

2) 5.5-6 gallons per quarter tank.

3) 3 gallons reserve after the fuel light comes on.

 

I can confirm the 26 gallon tank....but for the other two, I would say u are close and I mean really close.
