Reply to ELI5: Why do you have to turn your car off when you fill up your tank? by logan0921

do you have to? probably not. but i think the obvious answer is unless you're driving some ancient car, turning off your vehicle is literally gonna save you on gas since you're not wasting it idling for 5 minutes or however long it takes to fill up.

now imagine everyone leaving their car on when filling up? that'd be a huge waste of fuel overall.
