just a question for those who have been here longer and might have the answer from already asking. we have noticed that about 35% of the time, maybe a little less, the zip codes sent over the qc for p/u and del. addresses are wrong on one end or the other and sometimes both. we check the bol to confirm them against our gps provided zip code and they always match what we have. i dont think its ever a big difference in mileage that is shown, usually 10 or less but it is questionable when trying to pull up the address and all matches but the zip. i guess if i figured it, all the differences might add up to a few oil changes in a year. the real question is why does this happen. anyone asked about this before or is it just us.
