Hi,

My '01 very consistently threw the light on with four gallons of fuel left. The '09 I now have has repeatedly been within two gallons of empty when the light came on.

Try towing a 12k fifth wheel getting 10 mpg and see how close you want to cut it looking for a place to fuel up. So now when I'm on long trips towing, I have a five gallon container of fuel in the bed....
