Can't answer the network question, but I've also had success at Costco with PIN—both inside and at the gas pumps.
I've also had a few PIN-based gas pump transactions (not Costco) in the US that have never posted. This mirrors my experience with a China-issued ICBC UnionPay debit card, where US pay-at-the-pump transactions still haven't posted years later...
