Low Fuel Light

Judboy · July 3, 2014

How much fuel is really left with this comes on?

Based on my DTE and fuel economy I think ~2 gal

I usually fill up pretty close to when the light comes on. I typically put in between 23-24 gallons of gas.

You should fill up before the idiot light comes on. The fuel in the tank helps to cool the fuel pump. You will burn the fuel pump out faster if you constantly run down to empty.

I usually do fill up before the light, idiot. It is my first tank of gas on a new truck.

Next time be constructive and answer a question or keep silent if you do not know the answer.

Happy 4th!

Dealers run them near empty all the time....tell them they are destroying new trucks. BTW, where is this in the owners manual?

hmmm.....I've run plenty of cars til the fuel light comes on multiple times over. Never had an issue with the fuel pump burning out...

Sometimes things just make common.... well any way gas is cool (it better be) the pump is in there pumping getting warm, more gas cooler pump. Kinda like a bigger radiator on your car. Got to be better things to argue about.

Same here... been doing it for years on every vehicle I've ever owned. Fuel still goes thru the pump to help keep it cool. I think it's just another one of those common misconceptions.

You need to read up on the site rules. We don't need any name calling. I was adding to the conversation with a related topic. To fully answer your question depends on driving habits, speed, wind, temp, load, etc, so each vehicle will be different. It is definitely not a cut and dry number. Please excuse my ignorance for trying to put my 10+ years in the automotive field and ASE Master Certification to use and help someone. I'll keep my mouth shut next time you ask something.
