Ha! The first gallon of gas that I bought was 18¢ and we had gas wars that drove it down to 15¢ occasionally. OH! ...and there was no such thing as 'unleaded'. ...and no such thing as 'self service' - except at 3am. 😴
If you’re old enough to remember 18 cent gas then “unleaded” was around. It was usually called “white gas”. We bought it for Coleman lanterns and stoves. And they would pump it for us into a glass jug——boy, those days are gone.
