Costco Gas (or how to add a gas station)

[pedz]

On my iPhone, Costco gas does not show up. When I’m at the pump, I don’t want to spend the time to add it but I’m now home and I would like to do that.

1) Why doesn’t Costco gas show up? I believe it use to or it did once or twice. A different Costco Gas shows up far away but not the one I’m at. It isn’t new. Been here for probably a decade at least.

2) How can I add it while I’m now at home?
