When a gas pump is measuring your gas down to the thousandth of a gallon, are you really getting an accurate assessment of how much is going in?
Short answer: No.
Long answer: No.
As it turns out, gas pumps have an accepted inaccuracy of half a cubic inch, plus half a cubic inch per gallon. That means that if you’re getting 10 gallons of gas, then your gas pump can over- or under-dispense up to five and a half cubic inches of gas and still be compliant.
Five and a half cubic inches of gas is about .024 gallons, or twenty times the accuracy that your pump is claiming, so it’s basically all a lie.
