The Oldsmobile F-Series was a pre-WWII passenger car built from the 1928 through 1938 model years. The first generation continued the tradition of adding a series number for each model year; F-28, F-29, F-30 and F-31. The second generation, signified by a completely new bodystyle appearance was built from 1932 through 1938, all having been manufactured in Lansing, Michigan. 1926 saw the introduction of GM's most recognized business model, the use of common platforms shared amongst the brands, and Oldsmobile and Buick shared the GM B platform.^[1] The F-Series was shared with the Buick Master Six and was also known as the Oldsmobile Six which was introduced as a name earlier in 1913.^[2]

The F-Series was Oldsmobile's entry-level product using the Oldsmobile straight-6 engine, and was GM's mid-priced volume leader, offered in several body styles on a common wheelbase, while the Oldsmobile L-Series, with an Oldsmobile Straight-8 engine, was the top level vehicle with a longer wheelbase. It replaced the Oldsmobile Model 30 introduced in 1923, and was replaced by the Oldsmobile Series 60 and Oldsmobile Series 70 introduced in 1938.^[1] It was exported to Japan as a knock down kit and assembled at Osaka Assembly in Osaka, Japan.
