OK! Don't laugh at me on this one. I just need to know who can tell anything about the Frantz "Miracle" Oil Cleaners??? I managed to pick one up today and it needs a little cleaning up, but it is in very very good condition. It even came with the original paperwork. The Guarantee, Door decal to write the mileage when changed, Installation instructions, Owners guide, literature request mailer, the original Frantz decal, and the original purchase receipt. The receipt shows that it was bought for a 1957 Plymouth at 97,778 miles. I will get some pics of everything after the weekend and post them as I will be away until late Sunday night. If anyone can throw some info at me about this, please do so.
