MAPCO is a convenience store with many locations. It offers the cheapest diesel in the area, though the diesel pumps are noted to be very slow. The store is described as a nice gas station market without sketchy elements. However, some customers report issues, including being overcharged at the register with employees unwilling or unable to correct the price, and a requirement to prepay for gas. The service can be challenging, with a single employee sometimes dealing with large crowds. While it provides competitive fuel prices, these operational problems lead some local customers to avoid it.
