Miles in a tank question

Hey all so I have a 2016 4Runner 4x2 but with 20inch rims and grapplers I am getting about 315 miles in a fill up on my tank highway driving. My old 2008 with 17s got 375 to a tank do the rims and tires make that much of a difference?

It depends your driving conditions and style. I saw about a 1mpg gain when I went from 20x10s wrapped in E-rated 33x12.5s, to 17x8s with P-rated 285s. I now average about 22mpg driving it, and my wife averages about 19-20mpg. This is very close to what we saw with the stock wheels and tires (which we only had for a bit over a month). The current setup weighs very close to stock, while the 20s and 33x12.5s added about 50lb per corner (and it was definitely noticeable when driving it!).

I guess that translates, for us, to 437-509 miles per tank using all 23 gallons.

But, miles per tank is not a useful indication of fuel efficiency because it is difficult to consistently fill up from the same volume. One person who considers 1/8 of a tank "empty" might only go 250 miles between fillups, while another who habitually drives for 3 days with the fuel light flashing might get 350 miles between fillups. Without being able to define "empty" as a datapoint, these numbers are thus not helpful for any real assessment of efficiency.
 
I get what you guys are saying and I understand the miles to empty thing isn't something to rely on I just found it interesting how my old 2008 4x2 runner would fill up to 375 on the indicator and that was city and some highway everyday driving and this new one shows 315 with more highway then city. The engine tech is almost the same not like there are huge differences. I wonder if it has to do with not even having 2k on this one yet....

How often do you reset your mpg reading? I reset mine on every fill up (my OCD). But my range gauge usually only indicates around 330-340 after a fill up. It will obviously change as the tank goes down but I do the mental math between miles traveled and miles left and usually gain 10 - 20 miles per tank. Even with the gains it will only read 330-340 after the next fill up.
 
my 2016 will show 375 miles to go on a fill up. that is with the MPG showing 17-18MPG.

driving now in sw florida with all the traffic and stop lights not all that off on your lower miles to E.

after I had 3K miles on it and changed the bad rear diff gear oil/engine oil the MPG did go up. more like 20MPG now in swfl.

I think that the diff oil change made the diff but could also be the engine oil ....
