[3] The Oilers were a minor league affiliate of the Brooklyn Dodgers from 1939 to 1948, the St. Louis Browns in 1949, and the Philadelphia Phillies from 1956 to 1958.
[4] Starting in 2012, the Olean Oilers name was revived as a member of the New York Collegiate Baseball League.
The team began play in the summer of 2012, initially playing on the campus of Saint Bonaventure University before returning to a renovated Bradner Stadium in 2014; a crowd of nearly 2,000 fans watched the Oilers during their first game back at Bradner.
[5] In their fourth year of play as an amateur squad, the Oilers won the 2015 NYCBL championship; the next year, the team went on a 24-game winning streak near the beginning of the season, doubling the previous league record, en route to a league record 39 wins and a second consecutive championship, won before a league record 2,876 fans at Bradner.
Despite concerns over competitive balance as well as admitted discussions with the Perfect Game Collegiate Baseball League, the Oilers have shown a general preference to stay in the NYCBL for 2017.
