Average Miles per TANK/Average Gallons per TANK

[19963.4lsr5]

I’ve put 18 in all 3 runners already but I do not like going that low. On all 3 the 1/4 tank mark equaled 12 gallons. And usually between 220 and 260 miles.

Going almost empty and exposing the pump to me is not good. It runs hotter and shortens it’s life. Plus on my Saturn the long term fuel trim richens up. I don’t know if the toy does the same thing. Never had it that empty yet.

I have three different 4runners now and three different experiences in terms of the fuel gauge and how accurate it is. I attribute most differences in how much the tank seems to take at the pump to that more than I do how much the tank will actually accept.

For instance, my first 3rd gen would produce a low fuel light when there were about 5.5-6 gallons left in the tank. Once I knew that, I would routinely drive another 50 miles on road trips/on the highway. My current 3rd gen produces a low fuel light with about 2-2.5 gallons remaining. I get gas as soon as possible at that point.

Of course, once you get used to reading your fuel gauge, you can essentially estimate what your fuel mileage for that tank is going to be by the time it shows half a tank left. I have benchmarks in my mind as to what 160 miles, 180 miles, 200 miles means at that point. I'm referring mainly to highway driving.

The best mileage I've ever gotten is 23.6 MPG. That was in Colorado with an average elevation of 8000 feet and an average speed of 65 MPH. Better aerodynamics at higher altitude due to "pushing" a less dense air column as you drive, along with a couple other factors.

jumping back on this thread as I've never seen my tank fill up this much...

since I have other 4runners its odd that my 2002 allows the tank to be filled so much.

My 2000 stopped today at 13/14 gallons & my 1998 doesn't really go past 15 gallons either...

but my 2002 went over 18 gallons today! crazy as I though that was the capacity of the entire tank...I must have been running on fumes... I blame it on the supercharger




.

I routinely push mine to 17 gallons or so at fill up. My personal best was 19.1 gallons and it was starving for fuel as I rolled in the gas station. Like others I push it 50 miles or so when the light comes on. My average for the last 175 fill ups was 14.9 gallons and 253 miles.<GPS verified

When your fuel lights on its supposed to be 2 to 2.5 gallons of fuel correct? That really isnt much fuel to keep the fuel pump cool. I really dont like push the rig. The 19.1 is really impressive as I am not that brave. [ hats off]. I mostly refill at 1/4 to 1/8 or just when the light comes on.

Not necessarily true with the fuel light. These rigs are notorious for the fuel light coming on VERY early. I'm on my third and this is the only one that consistently produces the fuel light at the right "time." My others came on way early.

 

[Jidaran]

My light comes on with about 2 gal left in the tank.

Soon after I got it, I drove it for a bit after the light came on, since I figured I had a good buffer. I used maybe a gallon but certainly no more, and the 4Runner wouldn't start the next morning. Got it running with some starter fluid, drove straight to the gas station, and I've never pressed my luck again.

My typical drive varies widely between long distance road trips and inner city commuting, so I can get anywhere from 150 - 320 mi out of the ~16.5 gal it takes before my light comes on.

I'm almost completely stock, not making the adjustment for my 265/70s, which increase the mileage by about 3% from what the odo reads.

on my 2016 runner I put 9 gallons of gas in it when it drops to the 1/2 mark. tank needle sets at the full mark but it is not over full. I do this so I know that the needle is accurate. 4 gallons on the 1/4 area.
warm weather I get 20 MPG.. cold 30F then 16 MPG...
your 8,000 elevation ride does improve MPG because these vehicles have a poor wind resistance issue..
I have a 1996 chev Impala and I have no problems when the wind gets high cuts thru the air like a knife. 120 MPH runs like the 4runner at 70 MPH..hwy MPG 25 MPG @ 70 MPH on the Impala.

Yes, our 4runners certainly have a profile that is not conducive to being aerodynamic.

Regardless of the aerodynamic profile, however, colder weather and lower altitudes both contribute to a denser air column. Some vehicles (like the 4runners) are more affected but all will be affected to some extent. I remember driving back to Ohio from Colorado a few winters ago and all through Kansas, Missouri, and Illinois the ambient air temperature was below zero. Where I can typically get 20 MPG I was getting 14 pretty consistently.

After having a lovely CHECK ENGINE light come on for me, i was forced to take action on what turned out to be an AIR/FUEL ratio sensor... similar to an O2 sensor in regards to it being a sensor on the exhaust system.

thanks to [MENTION=10169]TheDurk[/MENTION] , i was quick to buy the sensor on amazon for around $100..

funny enough, i wanted to see what toyota would charge and the dealer wanted $323... like serious bro?!?! have you heard of a thing called "the internet".....


i have been getting better mileage but still nothing close to 300 miles....
but 260 miles is still better than the 220 i was getting earlier...


I'm still curious how i can fill my tank past 17 gallons...???


. . . .

Really would like to know what you're referring to?? From what I know there are only 2 O2 sensors and the A/F readings are given to the ECU from the upstream one, closest to the motor and before the cat. Please elaborate with a part number. I'd love if this were my issue.

thanks

 

[catrains]

if you have the code fault then the A/F sensor will cause the pcm to throw the code quickly if the sensor has a problem.

I did do this on a family members V8 runner. the A/F sensor fails around 80K miles if you have a remote start in cold weather and you like to get the heater working so your aZZ does not freeze up.

start it up and drive it then these O2 sensors will hold up ..

denso sensors .... do not buy at dealership..

 

[catrains]

your paying $4 per gallon ... my area $2.19 per gallon. shell gas 87 .
are the gasoline prices rising to $10 per gallon next year in san fran ?

 

[brillo_76]

So the consensus is the low fuel light can very. It always seem to be around 2 to 2.5 gallons for most Toyotas. Maybe those sensors arent supper accurate. I seen A/M fuel gauges and low lights be way off but most of my gas gauges were accurate. I have one that isnt but this also has an A/M tank in and I guessing fuel pump and sending units too. So i speculating the A/M maybe the cause. However, maybe I am wrong and its the luck of the draw.

I fill on the slowest setting. Depending on pump pressure holding the nozzle wide open the auto shutoff will vary greatly.

I'm comfortably getting 290 miles per tank in my 2002

Yea, I wanted to make the state line where fuel was $.15 cheaper!
Never thought much about the fuel pump (1st one died at 315k) but I do worry about tank sediment. Now my 01' Audi S4? Fuel pump was LOUD below 1/4 tank.

LOL.. Be glad your not in PA. We have the highest gas tax in the nation now. The great governor just raised it again not so long ago. We are now 58.7 cents per gallon now. :/ I can completely understand racing to the border for cheaper fuel.

When I go drag racing in Maryland their diesel is over 50 cents less than ours.

All states taxes are less on their fuels. We are #1 { Why it has to be on crappy things is besides me }. I am with you when I travel out of state. I mostly fill up at the border to save some $.

With my new fuel sender. Still battling wildly varying fuel economy though

As for gas prices, it's been between 1.97 to 2.25 recently.

 

[PRG3K]

I usually get 15.5-16 gallons and 300 miles +/- out of mine. I know this thing supposedly has an 18.5 gallon tank but I doubt I'll ever get close. The minute my gauge drops below the last line I'll start to get sputtering when the truck transfers weight around corners or even accelerating or braking too drastically. How's that possible with almost 2 gallons still in it?
