Chem products of Indiana oil additive,penatrating oil,and road tar remover

I recently got these at an estate by the case!
3 of these products were made in Princeton Indiana and the Chem-Fre penetrating oil was made in Kokomo Indiana
I think these are from the mid 60's and the Chem-Flo makes your engine go!Smells more like something you would put on pancakes though!lol

Thanks for looking!
