with a diesel 50 miles could be only 2-3 gallons driving on the highway (20-23mpg) so i've only seen my light twice, and i plan to avoid it..
The gas buddy app helps to watch prices too..

guys who like sucking big tanks empty at night.
We always have to look under our trucks in the morning, if somebody drilled a hole in our tanks.
So you better run on the bottom half of the tank, better fill just up what you need....day to day

I would argue with her that the gage was just not accurate and if anything you would get better on the last quarter because you weigh less. She never believed me but she was stubborn like that

I have 4 or 5 gallons left when the gas light comes on depending on how far to the gas station.

I have twice had the light come on when highway and in the hills. Highway was saying about 20 miles to empty this is in a moderately hilly area. Filled up - was 39 gals.
Another time up in the hills and said about 20 miles to empty, went past the 0 (over 27 miles to get to a station and filled up 41 gallons. Remember it is a light and a gage not an absolute. Consider the conditions when looking at the gage and when the light comes on. Flat driving vs hilly areas. I have also filled up with gage showing 1/8 to empty and put in 42 gals. Don't depend on the light or the gage. Diesel is a good thing!

Heck- I've had my Ex for almost 10 years and didn't know they have a low fuel warning light. But then mine is the 6.8 gasser and maybe only DIESEL drivers need one 
Alright- no flames - just joking !
