From their recent magazine:
The U.S. standard for fuel pump
accuracy is a variance of no more than
3 cubic inches per 5 gallons dispensed.
A cubic inch is a bit less than a
tablespoon – a very precise standard.
Costco tests all its fuel meters twice
a year. Our certi ed testers adjust any
meters that are off by more than 1 cubic
inch per 5 gallons, which is less than
one-tenth of 1 percent. If a meter shows
a tendency to fall out of adjustment, we
promptly service or replace the meter.
