How many remember ESSO before EXXON. Their slogan was put a tiger in your tank. Think that was ESSO.
When I was a kid, many many years ago, there were gas wars where stations near each other would cut prices and cut prices to lure customers away from the other stations. When I got my first car in the 60’s gas was regularly 25.9 cents / gallon and often 17.9/gal. I remember my dad buying gas for 14.9/gal.
Gas stations often gave premiums like a dish towel or dishes if you fill up. Fill up and get a plate, saucer, bowl or whatever the piece of the week was.
Many old stations were service stations that did oil changes, tuneups and repairs.
