BP in Rye (1 BOSTON POST RD)

Air pump is not self-service and theres usually a long line to wait to get tires filled.

Pretty much the cheapest gas prices around (at least for name-brand gas, there is a station a block away that might have slightly cheaper cash prices, but just by a few pennies), cash and credit has been the same price and includes full service if you wish. While the station had a service facility if you want full service there is generally only 1 attendant around so they try to juggle the full service stuff and the register duty at the same time.
