One of the biggest questions while you are traveling by car where to put the gas and how.
It is many gas stations along the route and almost all of them you can use it. For example the gas at gas station that on territory of wholesale clubs a lot of people thinks are only for members . Non members can still use them . Just in case if somebody ask You just say you forget your membership card and attendant slide they card and you pay with credit card that has to be Visa card. Before 2017 it was America Express only. As the Costco membership had agreement with Citibank as main provider and service for Costco. It is 2 more major clubs. SAM and BJ’s. They have own requirements. We will update info after checking them.
When you are paying cash most of the major cities are prepaid service. You go to the cashier, give them money and fill in. However when you are traveling away from the cities you still have old fashion. You fill in and pay after.
Regular gas stations are accepting all type of credit cards and cash. No limitations.
Another important matter to pay attention if you not from East Coast of United States. Most of the gas stations are self service but only one state and it is a law a full service. This state is New Jersey.
It is usually 3 grades of gas available. However wholesale club sale only 2 grades regular and premium. Regular gas stations sell regular, medium and premium. So far I only saw at Sunoco gas station it sell 4 grades. It had ultra that higher than premium.
