In any case, I won't know until I try.

If you don't have a gauge, your pump procedure needs to be as precise as possible to ensure reasonable reliability. Pumps are not terribly accurate. So... always go for a refill when the tank is down near empty. Always go to the same pump at the same station. Always fill at the slowest fill rate. Always stop filling at the first click. Doing this will minimize pump error and give you more reliable data for gauging your actual FE.
