Inexpensive gas here (and at the station on junction of Somerville Ave. and Elm St.). It's full serve to boot which is a treat. The employees are decent. They close at 10pm though so go early. Very busy right after work and the car configuration is awful. The side street along it is Victoria St.which is a one way - make sure you don't try to exit the station back onto Broadway via Victoria. Instead go left on Victoria and go around the block, lickety split. They also do oil changes and that sort of thing, although I've not tried them myself.
