How accurate is the miles to empty?

[Gvsukids]

24 gladiator the gas gauge doesn't seem as well defined as in other jeeps I have had. Where its easy to see half full and quarter. I have been going by the miles to empty numbers and am curious how accurate it is. Currently it says 80.2 miles to empty but the gauge looks close to empty. My jeep has just below 500 miles so have been babying it. What do you all think?

Thanks

Did you check out the threads ?

I just want to say, filling up at half tank will GREATLY increase the life of your fuel pump. The fuel actually keeps the pump cooler. When the pump is not submerged it will suck in more air and get hotter.

So, that said don't worry about how many miles you have left, refill your tank! LOL

i'd think the miles to empty is an estimate based off your current MPG and the computers guesstimate of how much fuel is left.

- yeah, that's been talked here many times already. Sorry, not real.
Guess you didn't read the whole thing, or the other threads.

You guys are basing some of this off old-school setups and what's been passed around the internet. That bit goes way back to the hot-rodder days of putting in electric pumps or the early factory electric pump days from the 80s. That stuff is decades old and doesn't apply here.

I wonder if people have even seen the modules used since the 1990s.

On modern tanks and pump modules there's really no difference between 1/2 tank ad 1/8 tank as far as pump temperatures or operation.
Many pumps sit inside of modules, and some use the fuel flowing around the armature to cool them, not submersion itself. So if any fuel is flowing, they are cooling.
Our pumps sit inside of a complex module unit, not hang in a tank like my SX4's submerged pump (which has never burned out)

What? People don't read the whole thread, or other threads?

So display said 48 miles to empty and went to fill it up. Took 16.3 gallons. Have always been filling when down to a quarter tank. For my old eyes this fuel gauge is harder to read. On other gauges the half mark and quarter marks are more pronounced it seems to me. The gauge was down close to the red line at 48 miles till empty.

I've got really bad eyes - and I guess I don't have much problem. The marks are each 1/8th marks. Half is dead-center. The quarter marks are a tad longer than the 1/8th marks.

This is just over 1/4

Just under 7/8 tank

On the other hand - this is extremely simple - only half and quarter marks - however, not as accurate, either! Not nearly as accurate.

I don't trust the computer with my life. So, for my wife and I, once it hits the 1/4 full mark, we fill the tank.

You don't want to find out what true empty is. No matter what the dash tells you.

Unless you are in a backwoods offroad situation, and can't find gas; Please fill it at 1/4 full if you can.

If money is that tight, and I have been there too, many many years ago; Consider a motorcycle or bicycle.

When I failed to fuel up at 8pm on a Sunday, by the time the light came, I was half way on my trip home. Nothing was open. I'm with you, 1/4 tank and start looking for fuel. 1/2 tank on Sundays past 8pm.

Brother, 1/4 tank is gas refill time.

But in my 1992 YJ, 1/2 a tank is refill time. Even though I replaced the pump and whatnot 5 years ago. It lies.

With my YJ, I got into the habit of refilling every 100 miles on the odo regardless of what the fuel gauge said. Because the fuel gauge lied and left my sister - in - law stranded twice 100 miles from home. I paid for the hassle of it all. She was saying, "WTF Eric"! My bad. mistake learned. But she ran it too low anyway.

Old cars need to be kept close to full. Newer cars need to refill at 1/4 tank.

The Gladiators, and even other new vehicles "distance to zero" is a SWAG. Scientific Wild Ass Guess.

You must have been raised in KS where there are no gas stations for half a day. (or so it seems)

Iowa used to be a place where there were more bars than any other business, now it's gas stations - they are everywhere, sometimes 3 at a single intersection.

Close, I grew up in rural Idaho. The closest city was 150 miles, either direction. Everything in town was usually closed by 9pm, and hardly anything open on Sunday.

Thanks to KwikTrip in Wisconsin, I can now get gas anytime. And a cup of coffee or even a burrito at 2AM.

But KwikTrip is still 20 minutes from home.

Enough space to run out of gas if you let it get too low.........

Yeah, plenty of places with wide open spaces between things. I've never been there so can't speak to Idaho but can imagine due to the location.

As a teenager, on my way to church at Christmas time, my worn out 1967 Jeep CJ5 gas gauge would read half tank and then drop to zero.

I walked to the nearest house & they let me phone home for help.

My brother showed up with a hose and gas can telling me to siphon from his Plymouth.

When I got a mouthful of leaded gas he began to sing:

“It’s beginning to taste a lot like gasoline everywhere you go…”

Sounds like a Chevy truck I had - you could go forever on that first half-tank and you thought you could get anywhere, wow, what great mpg.
Then when it hit half-way, where the hell is the gas going? Do I have a leak somewhere?
It was crazy. So you never went by the gauge as far as figuring how far you could go (the days before "miles remaining" displays)
Once you got down to 1/3 tank you had better be finding a station.

I personally have ran mine down to 35 miles to Empty and only took 19.5 gallons

For typical winter driving and higher speeds with my 2022, that would have meant 2 gallons left IF it was really truly tracking down to zero (which it isn't)
I figure 18 mpg, 2x18 is 36 miles, 2 gallons plus 19.5= 21.5
But it's not really quite that simple.
