If it was ever popular, it was a long time ago. I never remember seeing it. I do remember service stations having racks of glass bottles of oil with tin screw on spouts. The attendants refilled the bottles from large cans or drums. As I child, I survived my father's loyalty to Sunoco exposing me to the sight of the oil in glass bottles that they tried to dye blue. I still have Dad's bottle and spout that he used to change oil in his Nash with oil from 2 1/2 gallon square cans. Nash used a 327 cubic inch I6.

Kendall put their oil in glass jars during WWII, when the nation was conserving precious (metals, etc) resources to manufacture war materials, so your jar is about that vintage.
