Out of Covid Boredom I was cleaning out the old family desk today and ran across an oil change receipt as well as a Standard Oil Credit card receipt. I thought I would share how it was done back in the day and what it cost in Los Angeles in May 1940. Gas at .18/gallon and top of the line oil at .25/quart. Standard Oil was one of the top gas and oil stations. It was probably cheaper with the independents, especially in the cheaper parts of the country.
