I used to drain my tank until the low fuel light came on. These days I fill it whenever I pass by the cheapest station if I happen to be around. My cars do feel peppier when the tank is empty
Having a 38 gallon tank of diesel @ 7.15 lbs/gallon = 270lbs of fuel in the back at all times!
They were estimating an average car suffers 1-2% economy for every extra 100lbs of excess weight.
In my 8100lb truck, 270lbs is noise. I get my 14mpg regardless of going uphill or downhill with or without a tailwind :-(

Try running with 60 lbs (10 gallons of gasoline) strapped on your back. Also avoid quick starts and stops in traffic.
A gallon of gasoline weighs about 6.073 pounds per US Gallon.

2 very different vehicles, 2 approaches:
truck gets filled when almost empty; it doesn't seem to care how much, what kind, when, etc.
vintage car kept full as possible w/ ethanol-free to prevent condensation in the 41 yr old tank.

Somewhere between full and empty... lol...
I fill the car up when it gets down to 1/4 tank. The gauge falls fast after that. The wife wont tell me if the truck needs gas until the light comes on. Drives me crazy...

Often up to 1/2 capacity, hardly any over that, away from home with a lower price I have room to take advantage on a fill-up.
