context_page_description: Oldsmobile produced a straight-6 automobile engine from 1923–1950. It was a conventional side-valve engine of varying capacities and at stages was shared with GMC.
  Although the engines changed from year to year there were basically 5 series of Oldsmobile side-valve 6 cylinder engines over the 27 years of production, 1923 to 1927, 1928 to 1931, 1932 to 1936, 1937 to 1948 and 1949 to 1950. The '49 to '50 Big Six was to be the last inline six built by Oldsmobile although there were a few models in the late '60s and early '70s built using the overhead valve Chevrolet straight-6 engine.
