Mona Motor Oil

Mona Motor Oil — because nothing said "cutting-edge automotive technology" quite like a radio station and a promise that your car might stop bucking like an irritated mule. If your automobile was described as jumpy and jerky, congratulations: you were officially driving in the 1920s.
Mona Motor Oil proudly stood between civilization and a nation of rattling fenders, loose bolts, and passengers gripping the dashboard in prayer. Tune in to KOIL — because if the engine couldn't purr, at least the radio could.
