Do you resist the urge to prematurely top off?

I try to save as much money as I can on different things, gas is no different.
If I know gas prices are going to go up soon, I'll fill my gas tank up sooner than later. If I know gas prices will be going down or stay about the same, I typically wait until my gas light comes on at around 2 gallons remaining in the tank. Hope this helps someone!

Probably should have filled up last week, at 760+ miles on the tank now and the nearest E0 is 40 miles away. Probably gonna take a gallon with me just in case, but mpg for the tank is 45.2 so I might be OK.

I have no idea about coffee bean prices, but I have heard it is not a good idea to let the fuel get too low if the pump is in the tank (in-tank pumps are very common). The pump is cooled by the fuel and if it becomes uncovered because the fuel is very low, it could overheat.

One of the side effects of not burning much gas is the the fuel pump works less. It doesn't get heated up as much as one in a car being used normally.

Ever actually had a pump get hot? Me neither. And I run 'em 'til they're dry.

If I remember correctly, most of the cooling is from the fuel moving through the pump. So as long as the pump isn't sucking air, it should be fine.

Also, on most cars the fuel pump doesn't speed up or slow down according to fuel use. Instead, the fuel system just returns more fuel back into the tank. So the fuel pump isn't working much less, if your engine burns less fuel.
