what happened to thr old stuff can’t buy

What specific products are you looking for?  I may be able to give you more details about MMO products, I just need the name and/or product number.  The product number is located on the back label and will start with MM.

I’m looking mm that you poured in oil that helped with valve guides,metal can.

We no longer manufacture MMO in the metal cans.  The formula is very similar to the orginal Marvel Mystery Oil formula from the 1920’s.  You will be getting the same effective performance from the current formula.  If you are looking for the old cans as collectors items, I have found that ebay sells them.  Please let me know if you have any other questions.
