"Commercial" style superior engines like this 35hp model shared some components with the simpler "oil field" style, but were distinguished by dual-ignition systems, power-actuated intake valves and an overall higher quality finish.

Organized by P.J. Shouvlin in 1893, Superior built commercial and oil field gas and diesel engines in sizes from 10hp to 600hp. This company has a long history, taking over the Otto Gas Engine Works in 1923, being taken over by the National Supply Co., in 1928, and presently existing as a division of White Consolidated Industries.
