Long time ago I read somewhere you shouldn't hold the lever all the way because it could potentially allow more oxygen through and thus have to pay just a little bit more for the same amount of fuel. Is that really true or was I being gaslighted?

The metering is done in the dispenser, not the nozzle.

Yes, but can having the nozzle not 100% open influence the metering?
