Gas Mileage? How far can you go on a single tank?

Looking to get some info on how many miles people are getting on a single tank of gas (no load)?

I have a 2011, double cab, L/B, with a 5100 series billestien leveling kit, LT285/70R17's BFG's, and averaging any where between 290-300 miles per tank! When I fill up, I fill up completely, then run the tank down till the fuel light comes on and get 290-300 miles per tank. I don't have a heavy foot, spend time on both freeway (Avg 65-70mph), and city miles (various speeds), take off (from stop sign/light) slowly, and 'coast' (without foot on the gas) until I come to a gradual stop.

I know some guys out there that get any where between 320-350 miles per tank...any ideas/suggestions on what might be causing this!? Or am I just S.O.L.???

no free lunch. big tires?

i agree with whip. miles per tankful is not accurate. the math is much easier, but accuracy suffers. no shame in having a calculator on board.

 

I filled up to where I can see the gas in the spout and drove 406 mi @ 70mph on a single tank. I was heading to Vegas 6 1/2 hr drive. I have a SC though and my truck never down shifts on inclines so that helps.

 

Like OZ-T said, scroll all the way down to the bottom to see similar threads, or simply search "mileage per tank"

I've noticed my fuel light turns on after using 16-18 gallons and is way to inconsistent to use for determining mpg. It's purpose is to warn you before you run out of gas. If you're taking the time to watch you driving habits to improve mpg then you should be tracking mileage between fill-ups and divide by gallons pumped rather than going off of something inexact like "per tank." If you lack the math skills or too lazy to divide (like me) then use fuelly.

 

406 miles was my best tank.

 

I usually get close to 350 before I fill up. Never let it get down to where the light comes on.

 

4 cyl

 

I usually get around 280 a tank

 

average is around 320-350/tank off the odometer. My calculated MPG is around 17.2-17.9. If you have an android phone I would suggest downloading an app called "acar" it helps you track all expenses for your vehicle including fill ups and MPG. It will forecast when your next fill up is due, warn you when an oil change is needed, breaks down the avg. cost of operation per day an a lot more. It can track multiple vehicles and the best part is, its an awesome FREE app. You can buy the app and get more features like exporting to an XL file and a few other things, but I have not found the need to use the additional features. This may help you track better.

 

x2 but that was a trip to Vegas crusin at 70 all the way out

 

I average about 320 per tank before I decide to fill up, and that is usually just after the gas light comes on. Been city driving a lot more lately, so that has gone down a tad.

Best tank was like 370 miles. Since I started (recently) tracking, best MPG was 21. Avg MPG right now is 19.5... 2012 DblCab V6 Auto

 

well just the different base models will affect totals...
so with mine-
I have a 2012 DCSB 2.7L 4 banger.
I get right around 340mi when the light comes on.
averaging around 18mpg. this is virtually all city driving though. many short trips throughout the day & in traffic.

Im still puzzled how some guys with the v6 versions of my truck are claiming to get 18+mpg...
I had a 2007 and never got 350-370miles per fillup unless it was all hwy driving. but it did get regularly 300-320miles per fillup.
My trucks were/are bone stock. no mods.
Pretty sure these guys are calculating something wrong or padding the numbers.
so I guess its true that the 4cyl vs' the 6cyl will only gain you around 20-30miles per tank?!?

 

245 is my best

 

I get 18mpg all city on a bad week..and i have a 3" lift and 110k miles, it may have something to do with your driving habits or possibly your truck may need a tune up..idk

i usually get 21.5 mpg on highway trips if i keep it at 65-68mph

my calculus skills far exceed computing gas mileage

and ill admit i do drive like a grandma, and i rarely sit in traffic, but if i was getting 340 to a tank id switch back to a v8 chevy

 

I get over 300 a tank every time unless I'm wheeling.

I avg about 22-24 highway
and 19-20 city.

 

Last tank with my 2012 V6 around town was 19.8 and I calculate each tank. I rarely drive over 65 and always coast when I know I have to slow down or stop.
No padding here, it is all in the foot.

 

i guess by "tank" standards i get 388 city and 451.5 hwy

although id never measure my mileage that way..the gauge is horribly inaccurate

 

searching works wonders.

 

so your telling me that you could go fill up your tank(19gallons and some change?) and drive 380miles-city driving?
idk about that

humor me for a second - just to confirm my calculations...
if I fill up 18.5gallons and drive 340 miles thats around 18miles per gallon.
how is everyone else calculating this? am i doing something wrong here?

you have a heavier truck(4x4), larger engine & larger tires...???
