Re: Gasoline in the 30's and 40's
The tetraethyl lead was one thing but the gasoline formula was also different at the time. The catalytic reforming process wasn't developed and put into use before 1949. This allowed the lower grade naphtha to be changed to a higher grade.
The old tractors were still running on Kerosene back in the 20s & 30s. Poor folks used wood gas in some cases.
