The Signal Gasoline Company began in 1922 when farmer Samuel B. Mosher started his first filling station. Mosher became quite a businessman with strong entrepreneurial skills as the operation quickly grew during the 20’s and in 1928 was renamed Signal Gas and Oil. In 1931, Signal partnered with the gasoline and oil giant, the Standard Oil Company.
Signal eventually grew to be the largest independent oil company on the West Coast. Signal Gasoline was known for its premium quality.
Garage Art Family History with Signal Gasoline:
In 1956 my grandfather bought a Signal Gas station and ran it in Seattle Washington, West Seattle off California Ave for several years. Since then, our family has collected several Signal signs including the one pictured above. This picture below was not his station, but comparable to what a Signal Station on the West coast looked like and how it was set-up.
