When the low fuel indicator comes on, how many gallons are left usually? I notice the mileage range indicator just says "Fuel Low" so it's impossible to say.

I dont even think my light goes on.. It goes so close to what I would assume is no gass at all and doesnt light up. My solution is not to run it dry :)

It will vary from car to car but heres a little food for thought - the fuel pump lives in the tank. It is an electric pump and gets warm while it is working. It uses the fuel in the tank for cooling.

1 - Letting the tank run almost dry will cause the pump to not be cooled as effectively and will shorten it's life.
2 - No one wants to be "that guy" hitching a ride with a gas can because he thought he could make it 2 more miles ;)

Low fuel comes up, time for a pit stop :twothumbs

My low fuel display came on right after I bought the car. I was in Bel Air, MD dricing to Glen Burnie, MD (About a 45 minute drive) It came on about 10 minutes into the drive. I got to the gas station and noticed the never game a fucking key for the gas cap.

To make a long story short, I was able to drive the rest of the way home, get a screwdriver to break the cap off, and was still able to drive to the gas station to fill up. I probably had less than .2 gallons left in the tank.

How much gas is left in the tank varies. The low fuel warning comes on when you have 50 miles or less until empty based on your current average MPG. So, if the DIC says you are currently getting 28.5 MPG then when the low fuel indicator comes on you have approx. 1.75 gallons left. The thing to remember is that since this is based on the computers calculation of MPG it will not necessarily be correct, especially if you start driving more aggressively. Best thing to do is simply put gas in once the indicator comes on so you don't have to worry about it.

The car had probably been used mostly on test drives so the MPG was more than likely off due to the car not being warmed up and being driven more aggressively. The low fuel light probably came on based on 50 miles left at like 25 MPG, so like 2 gallons left. However if you were driving mostly highway you would have been getting about 30 MPG or more. So in reality you had probably 60 miles maybe a little more when the low fuel indicator came on.

Never let it go below a 1/4 of a tank and no worries

you have about 3 gallons left when the light comes on, i've gone a full 100 miles with the low fuel light on once.

he was trying to say that the fuel cap had a lock on it. lol. and that he never got a key for it.

I have already explained how it calculates the low fuel indicator. If you drove 100 miles once the light came on then the computer was averaging your MPG at 15 MPG. You must have been driving like a bat out of hell or your injectors are configured way out of wack.
