Movie:Down the Gasoline Trail (1935)

Here is a great little film made by Chevy - informative and fun.

Cartoon showing what happens to a drop of gasoline from the time it flows into the gas tank to when it is exploded in the engine cylinder. This "fantastic voyage" through a glisteningly clean Chevrolet engine is an excellent example of the soft-sell industrial, where the product that's promoted is hardly ever mentioned by name.
Producer: Handy (Jam) Organization
