In the 1950s-60s, 2 gallons were made for various brands of gasoline combined with AC plug ads on them. To date, I have Signal. Phillips, Buick, and Skelly versions. I know of Cities Service, Atlantic, Pure Firebird, and Sunoco left to get.
If you have any of these, or a brand I did not mention, PLEASE, contact me. I will pay up to complete this set.
Good oil cans don't wait for people, people wait for them.
