The front panel specifies that the SAE 30 oil is intended for power mowers, stationary engines, air compressors, tractors, and conveyors. The reverse side provides technical details, stating the oil contains a substantial proportion of Shaler Rislone and provides a caution regarding monochloro naphthalenes. The container is constructed of metal and retains its original metal screw-top closure.
