MMO is a solvent "oil." It's basically a mixture of petroleum based
solvents with Wintergreen (methyl salicylate) for scent, and red dye for
color. It can dissolve the gunk that clogs the small holes in hydraulic
lifters, or elsewhere. Low oil pressure in worn WBX engines keeps the
lifters from pumping up, and it's worse when they are clogged as well.
It was concocted in the 1920s, when oils were primitive (no detergent
additives), but it still has a useful purpose, it would not still be around
if it didn't. Check out some aircraft forums, it's very popular for
airplane engines. Those are engines you really depend on, and many from the
'70s are air cooled flat fours!
Would you fly in an air cooled VW? Many people pretty much do.

It did well for a while, and really seemed to get the noisier ones unstuck,
but if the van set for a week (or sometimes less) and hadn't had the oil
changed recently, I'd hear them for the first 20 minutes of driving. I
bought new ones and want to make sure that I don't do something wrong by
mistreating them. My first set went over 160K miles without giving any
problems, I hope I get that much out of these.
Marvel Mystery Oil. Isn't that the greatest name? Perfect American marketing
BS in the legacy of guys selling snake oil to a crowd of yokels off the back
of a wagon. It has this shroud of the occult, like it was pressed from
egyptian mummies or hummingbird tongues. Does anyone really know what the
mystery really is?
