How Far Can You Go When The Fuel Light Comes On
Member's How far have you driven your Monte Carlo on Empty ? How far ? WoW
1/4 in 8 seconds

Posted: Nov, 03 2009 | By: Jonathon Ramsey | AOL Autos




While some cars tell the truth about their lack of fuel, others will give you a few extra gallons. (Creative Commons photo by t3mujin)








Warning lights in cars work almost like the electrodes scientists use to test responses in lab rats: a current is run through them, and the subject reacts in some novel way to the stimulus. Leading the way for dashboard stimulation, as far as cautionary alerts go, would be the "Check Engine" light and the "Low Fuel" light.
The check engine light might inspire the most profound responses because it could mean just about anything, from a faulty sensor to imminent vehicular implosion and a gargantuan repair bill. It’s like the doctor telling you he has to run some tests before he knows what’s wrong with you, but it could be either an ear infection or a brain tumor.
It is perhaps the low fuel light, however, that is the most legendary and creates the widest range of responses and means the most to people. There is practically an industry built around the tiny stencil: it has its own website, it brings up more results on Yahoo and Google than other warning lights, there have been mantras created to defer its consequences, it has been called a liar and worse, its accuracy is tested more often and more vigorously than a law student’s, Jackson Browne sang a song about it (Running on Empty), and it has probably been responsible for more appeals to a higher power than any car-related activity save love by the dashboard light.
Ten Very Fuel Efficient Cars







That’s quite a following for one tiny bulb.
The cult of the Low Fuel warning light is strengthened by the fact that few people have any idea what it really means when the light is illuminated. Your car’s owner’s guide might tell you how many miles you can go when you hear that warning chime, but that’s just a handy thumbnail -- how far you can actually go depends on how much gas remains in the tank and where and how you’re driving.
In fact, even the people who make the cars aren’t always sure how much gas is left in the car when the red flag goes up. That’s why some other owner’s manuals, such as those for Honda and Acura vehicles, won’t even guesstimate the distance to truly empty.
"The amount of gas left in the tank when the low-fuel warning light illuminates," said Honda’s Chris Martin, "varies greatly from car to car even within a particular model line."
So just because you are intimately acquainted with the camel-like habits of your Honda Civic after having tested it a few times, that doesn’t mean you should can expect the same or better performance from the smaller Honda Fit.
"It's impossible to say exactly how much is in the tank when the light comes on," continued Martin. "For that reason, we recommend that a driver attempt to refuel as soon as possible when the low-fuel indicator illuminates."
Combine "impossible to say exactly how much" with variations in driving factors that include tire pressure and weather. Then add in the fact that carmakers still want the car to start, even if it’s light on gas, when it’s at an incline -- like when you’re getting ready to go to work in San Francisco. Finally, note that the fuel gauge isn’t exactly the most precise instrument our civilization has created; we’ve driven several cars that ran flawlessly at 70 mph for miles when the needle was below the "E."
Forums are full of drivers commenting on how much gas they have in their car even after the warnings have seemingly reached Def-Con 1. It is no wonder then that when folks talk about how far they’ve driven with the low fuel light on, they sometimes speak as if it were an Act of God. A Canadian journalist who ran several cars until they stopped got 98 miles in a Hyundai Elantra after the warning light, but just 58 miles in a Kia Spectra -- which is a smaller car utilizing the same engine as the Hyundai. Another driver actually got angry when he was able to get his Dodge Grand Caravan another 110 miles on a supposedly nearly empty tank.
And as hybrids gain market share, that kind of distance-after-"E" won’t be so strange. Running out of gas in a hybrid has the potential to severely damage the hybrid system, so carmakers will be especially cautious about making sure consumers have time to get to the pump.

Hard numbers about the remains of the tank still aren’t easy to come by, but Lexus tries. "One to three gallons," said Lexus’ Bill Kwong, "depending on the model."

That, however, is about as far as they’ll go when it comes to pinning things down. On the matter of how far you could actually go with your one-to-three gallons, it was back to general terms.

"If the vehicle provides a ‘distance to empty'," said Kwong, "it's a conservative estimate of what's left in the tank based on a conservative estimate of the current tank mpg. The distance to empty for the driver will vary based on the vehicle, load, road condition, weather, tire pressure and driving style."

Mercedes offers a much more precise look at how much gas you have left: owner’s manuals provide a chart of how big your car’s gas tank is and how many gallons -- approximately -- you have left when things get dicey. The GL, for instance, has a 26.4 gallon tank and around 3.4 gallons in reserve. The C-Class has at 17.1 gallon tank and keeps about 2.1 miles in reserve. Taking the average mileage for both vehicles, you should get 60 miles in the base model GL Bluetec, and 45 miles in the C300 Luxury Sedan.

That is, until you read the caveats.

"The mileage number is monitored by the engine management system and takes into account current fuel usage and driving style to calculate remaining mileage," said Mercedes’ Nicole Weiss. "This number is also very sensitive in the reserve range and changes drastically based on throttle demand."

Weiss went on to enumerate the steps you should take if you want to prolong what little gas you have left.

"Turn off the air conditioning," she said. "Close all windows if possible, reduce your speed, no jack rabbit starts from stand still and only enough [power] to keep the vehicle at speed. Correct tire pressure positively affects the overall fuel consumption."

Nevertheless, the safest bet is the one offered by all three carmakers, nearly verbatim: in the words of Bill Kwong at Lexus, "When the low warning light turns on, the driver should really fuel up as soon as possible."

Of course, a heartfelt prayer and that mantra probably won’t hurt, either:


Gods of Petrol, fuel, and gas
Expand my fuel and do it fast!

Running On Empty - 2003 - 4:55

Looking out at the road rushing under my wheels
Looking back at the years gone by like so many summer fields
In sixty-five I was seventeen and running up one-o-one
I don�t know where I�m running now, I�m just running on

Running on - running on empty
Running on - running blind
Running on - running into the sun
But I�m running behind

Gotta do what you can just to keep your love alive
Trying not to confuse it with what you do to survive
In sixty-nine I was twenty-one and I called the road my own
I don�t know when that road turned onto the road I�m on

Running on - running on empty
Running on - running blind
Running on - running into the sun
But I�m running behind

Everyone I know, everywhere I go
People need some reason to believe
I don�t know about anyone but me
If it takes all night, that�ll be all right
If I can get you to smile before I leave

Looking out at the road rushing under my wheels
I don�t know how to tell you all just how crazy this life feels
I look around for the friends that I used to turn to to pull me through
Looking into their eyes I see them running too

Running on - running on empty
Running on - running blind
Running on - running into the sun
But I�m running behind

Honey you really tempt me
You know the way you look so kind
I�d love to stick around but I�m running behind
You know I don�t even know what I�m hoping to find
Running into the sun but I�m running behind



Listen on: iLike - Pandora - iMeem

I know the Monte really well, and when the "Fuel Level Low" message appears on the drivers information, that means I still have a good 50-70 miles depending on what kind of driving i'm doing. Once the needle is completly barried on E, that means I have a good 30 miles till I run.

I've ran out of gas once in the Monte. That particular time I had gone like 65 miles since the light came on....then I ran out on the highway. OOPS! I thought I could make it to the nearest Chevron since I had gone 73 miles before after the low fuel light came on. No such luck this time. hahaha.

My car never sees under half a tank. You never know what kind of traffic you are going to get stuck in, plus the only time I have a correct fuel reading is when I first start the car (too lazy to spend the money on my sending unit right now)

Also I've always been told that you allow room for moisture and line freezing in the winter when you have less fuel in the car, so I especially don't let it below half a tank in the winter time.

I'm afraid to find out in the Monte. With my luck I'll be on the highway out in the middle of no-where.

Or maybe I've seen too many horror movies.

I've gotten 18.3 gallons in mine before, and its only a 17.5 gallon tank. It was still running when I pulled up to the pump...?

Man, if I got gas when mine had half a tank, i'd spend half my life at the gas station. LOL. I fill up every 3 to 4 days usually taking about 17 gallons to fill up. I typically get about 450 miles to a full tank. Half a tank is gone in like a 1.5-2 days! LOL

When I lived up in the Poconos, I used to visit a gas station twice a night on weekends!

yup, mike knows the joy's of the poconos, lol. the nearest gas station to me is a 16 mile round trip... to get DECENT gas, its 20+ thats going down towards stroudsbrug... i mostly run around on the mountian, so i tank up whenever i pass the gas station, 'caus A) my fuel guage just wanders from "E" to "F" constantly, so i go by the odometer, and
B) it SUCKS to run out of go juce near my house, lol. loooong walk, lol.
