The moral of the story is... When your tank is on 1/2 empty, fill it up.
We ran our CRD down to zero once on a long trip. The place we planned on
pulling off had no diesel so we had to go to the next exit that was 30 miles away or so.

Correct me if I'm wrong but on a WK 3.0 CRD the diesel rails injection systeme needs to be bleed before running the enegine after a dead 0 zero empty tank ?

Don't know.... we did not actually run OUT of fuel.... the indicator simple read ZERO miles till empty and we made it to the next station holding our breath.

I hope to never actually run out.

almost every vehicle i've owned that has an "almost empty" light, gave me about 50 miles to find a gas station.

Thanks for the info on keeping a quarter tank full... hopefully, my pump hasn't been smoked by me running it almost dry twice!

I always told my kids that the last quarter tank of gas was MINE... just in case I needed to use the car I bought for them to get to work some day.

My dad taught me that its easier to keep the tank full than push a car with an empty tank.

I let mine run dry... just to see how far down the fuel gauge would go. And to see how much useable fuel there is in the tank.

after I hit '0 miles to empty', the fuel gauge went down just a bit (probably 20 miles worth of driving), then stopped moving altogether. I went on until the engine stopped from lack of fuel.

Took 20.4 gallons to fill the tank. I wish the fuel gauge would keep dropping until the tank is empty. There's probably over 2 gallons left in the tank when my gauge stops moving.

Next I'll track how many gallons it takes to fill once '0 miles' is displayed... if it's the same amount, that would let me know exactly how much fuel I have left (since I know I can burn 20.4 gallons with a full tank).

If you run less than 1/4 the cooling capacity of the gas is not nearly what it was when full and your pump will run warmer. If you run like this often you will probably become a victim of a fuel pump failure after your factory warranty expires. (Pumps like this know when it's done and they wait until 100 miles after the warranty expires before quitting.)

My ZJ's fuel tank wasn't allowed to dip below 1/4 during it's life and it went to 180K miles before it bit the dust.

Yet, my 99 WJ went too low once (thanks to the wife) and it quit around 45K.

I know it stinks to have to fill up more often, but fuel pumps cost almost $550 just for the pump, and it's usually another $200 in labor to change. Save yourself some money and fill it up more often.

Also, when filling up, try to top it off. The filter in the fuel tank is cleaned when you fill it up. The debris reside in the bottom of the tank where they stay until you pull the fuel pump someday. They will not hurt anything there. If you don't clean the filter by filling up the pump will have to work harder to get the required fuel pressure and eventually it will result in premature failure of the pump as well.

BTW, if a pump lives to 150K, it has surpassed it's life expectancy.

Just trying to pass a little info.

Agreed that is definitely causes problems to run out of gas in a modern car. At a minimum you'd want to go ahead and change out any and all fuel filters, but it still might shorten the life of components.

The only thing I'll add is that "topping off" is probably fine in ZJs, particularly the older ones, but you generally should not do that in newer cars with all the extra evaporative emissions equipment. You can end up with liquid where vapor belongs and it can muck up some of that stuff, mainly the charcoal canister I'm guessing.

I once drove around for my day with a 2 gallon gas canister in the trunk for the sole purpose of seeing how far I could get after zero till E. I honestly drove 35+ miles and said fk it and put gas in. Ridiculous vehicles.

This might be a dumb question but when you guys say "the computer shows 0 miles" do you mean in the speedo cluster ? I'm new to the Jeep community, and my navi has the dead black screen, so i'm wondering if you can toggle the info that displays under the RPMs. All mine is showing is that I need to perform service, service parking assist, and my tire pressures on the front left, right and spare is low.

Thanks

On my 2000 WJ 4.0, I ran out of gas on the interstate several years ago. I knew the gas gauge was low as heck & the computer was showing me that it was almost at 0. Once it hit 0, it only took another minute or 2 before everything started locking up on me & then I could barely steer onto the grass off the interstate. That definitely sucked.

you need to fix your problems, and then the display will show you all the info about miles to empty, temperature/compass, etc.

download the owner's manual from wkjeeps dot com if you don't have a paper copy. it will tell you how to reset the 'perform service' message.

you probably know how to get rid of the 'low tire pressure' warnings.

service parking assist warning... my wk doesn't have that so I have no idea how to clear, but maybe the owner's manual has some tips on how to do it.

I test out my vehicle's for this whenever I first get them. On a weekend when I'm bored, I'll put a 5-gallon gas can in the back and drive it till it dies, exactly 5 gallons. On my 05 WK 4.7 , the gas light came on with 30 miles left according to the computer. I continued driving a mix of Highway and city, but mostly Highway. Average speeds, not trying to deviate from my normal driving behavior. When the computer read 0 miles left, I reset the trip odometer. At around 55 miles there was a definite stutter, probably do to turns and the little bit of gas moving away from the pump. At 68 miles, complete power loss, engine died. Did not attempt to restart. Once the 5 gallons of gas was put in I gave it a few minutes to sit and leach some of the fuel down the lines. After maybe 10 minutes, turned the ignition for about 3 or 4 seconds before it fired right up. The nearest gas station wasn't too far away, maybe a few miles. Once I got there, I remember putting in just a pinch over 15 gallons. Let's say close to 15.15 gallons. Back in 2011 when I bought it, it had about 55,000 miles on it (with light engine tick). Now it has about 140k (still has light engine tick, love ya Rikki Tikki Tavi!). No issues with the fuel pump. Although I have run it down to 0 at least forty or fifty Times by now , I do my best to not make a habit of that anymore. (was unemployed student for a year) And agreed with the winter/bad weather driving, don't ever let it get under a half tank. That's just stupid and asking for trouble. My general rule of thumb for Rikki is, if I turn on the ignition and the gas gauge moves a little bit, (woo hoo it wiggled let's go) there's enough gas to get across town! Small town, not big city. About 60,000 people.
