I would have expected a slightly lower loss, so more miles per tank on gas. However, no two pumps run at the same pressure so you may find a variation in the amount that goes in depending on where you fill up. Also, the amount you get will differ with temperature too. So checking on just one tankfull is not strictly accurate, your tank may not have been completely full on the initial fill up but is now.
