The last one (north) is the one I used and had no problems.I don't know how much we paid per gallon but we got scammed on the way back to the USA this weekend. We stopped at what we thought was the last Pemex in Rocky Point. There used to be a convenience store there and we always stopped there with no problems. It was always self serve. Anyway, someone ran up to my husband and insisted on pumping for him while another guy came up to me and asked for my credit card. I had read on the board earlier about watching the credit card so I never let it out of my sight. It seemed strange that it only took the guy a couple of minutes to "fill it up" but it was $24.00 and that sounded right because it wasn't on empty. Once we got on the road the guage wasn't even 3/4 of the way full. The attendant didn't clear out the previous customer's total when he started pumping our gas so we probably paid double for the little bit of gas we got.
Just a few feet down the road we noticed a new Circle K with a gas station so I guess the little convenience store has resorted to scamming people to make money. BEWARE!
Knew I should have paid on the way back... Still had a great time...
