I have this old gas can that I still use for my mix. It was my dads can that he used for his chainsaw mix for as long as I can remember. I’m 60, almost 61, but as far back as I can remember he had this. I cleaned it up today to see if I could find a date anywhere on it, and don’t find one. It still works just fine. I positively know it’s over 50 years old.
