Low Fuel Warning

LakeShow · 09-08-2012, 04:39 PM

I swear once I get under 20miles remaining, it all the sudden turns to the three dashes "---" indicating no miles remaining. There must be something seriously wrong with my fuel sensors.

No, it's normal. I have the same. So when my fuel indicator has 2 lights left, it shows roughly 40 miles left. And then when it's down to 1 light left, it will turn into "---" like you mentioned. From my some daring experience, you roughly have 2 gallons left with 1 light and 0.5 gallon left when all lights are gone.

Just to share my recent experience. 2 dots left and flashing low fuel with about 38 miles remaining. Filled up the tank with 18 gallons. So I have about 1 gallon left in the tank based on the 19 gallon capacity. I suppose the computer is off by about 20 miles assuming I get about 18 mpg unless there is some sort of reserve capacity beyond the 19 gallons.

I was thinking of doing an experiment. When the low fuel warning comes on (two dots) reset the odometer and drive it until it runs out of gas! To see how many miles you really can go... But I am kinda scared. lol

Don't do it buddy. And it's depends. If u going to do the experiment. Pls do the following for us too.

Do it and run normal.
Do it then run aggressive.
Do it when u sit in the traffic.

I'm just kidding. Well don't do it!!!

By the time I hit the next mile, it "----" out as if I have no fuel left. Because of this, I have no real Idea when I will really run out of fuel. While I don't mind stopping and getting fuel once it says 40 miles left, I would hope it never happens when I am on the freeway with 5 or 10 miles to the next gas station.

Anyone else have this issue?

Your fuel pump is cooled by the fuel in your tank so letting it drop low will overheat your pump and cause an early failure,, this goes for all cars with an in tank fuel pump...........

I also have a flaky fuel gauge but an FYI you should try to keep about 1/4 tank as the internal fuel pumps are fluid cooled don't want them to fail prematurely

I've heard this mentioned several times. And I know Nissan is stupid. But I seriously wonder if the pump relies on gas in tank to keep cool. Or at least how much fluid is needed in the tank to keep it cool.

FWIW, I typically use 18+ gallons every tank - rarely do I fill up with less than 17.5 gal. After nearly 70K miles, and a number of brutally hot Texas summers, I've had zero issues with my fuel pump

TexasChuck · 06-09-2015, 03:47 PM

Just my Opinion. The fuels probably lubricates the pump, and cools.

nis350 · 06-09-2015, 04:25 PM

I think it is fine as long as gas is being pumped through regardless of the remaining fuel level in the tank.

I did hear that some fuel pumps are lubricated by the fuel, but I don't know if it is the case for our cars.

I've had the same problem on both my 09 Base Z and '12 Roaster Sprt.

i was on a road trip this week and wasnt paying attention- heard the Chime, looked down and it said ---- miles to empty. made it 14 miles to the nearest gas station. was sweating a little but she made it LOL

kenchan · 06-11-2015, 09:51 AM

i fill when im at like one dot over half. mostly because i dont drive my hobby cars that much so i want to keep cycling fresh fuel in there...and also for keeping the sensors lubed. no issue with no dots at top 6yrs old this yr.
