Marvel Mystery Oil012R Oil Can, 16 oz. (Pack of 6)

I use it in my fuel. Greatly improves performance

Just a dose of this in every tankful ensures a multitude of positive results.

This is GREAT STUFF that I have used professionally since college, and I am 70 now. This is good for high detergency cleaning of varnished internal combustion engine parts, tools and general high pressure lubricant uses. Works well mixed in regular AND Synthetic oil in modern engines that rev higher with higher compression ratio pistons and rings, good to clean AND protect any engines that I run.

What can be said other than MMO works, I use this in my Harley to keep the oil flowing and clean. I also keep some at my hangar for airplane related items.Why buy a case, well easy, you can never have too much MMO around when you need it.

the caps on two of the containers were lose and leaking

good stuff

Works as expected.

Goota take it on faith; but decades of lore is probably accurate. If you want to keep a legacy engine humming along this is the stuff. I use in my airplane to keep my top end lubed and cylinders from coking up. Small engine repair store said my weed whacker was seized and i needed a new one. I dumped this stuff in the spark plug hole and started it up a few hours later. I bought an old lawnmower that did not run... same story.
