A fine air tool oil and more
I've been using Marvel Mystery Oil for my air tools since the early 1970's when an elderly mentor told me to use it when I was a young man just out of the service on my first civilian job. It works fine and my air tools have always lived a long and useful life with out gunking up or showing much wear. It has never failed me. I also use it for a general light lube oil and when mixed with a little lacquer thinner it frees rusty bolts about as good as anything else I've tried. My elderly mentor had been a mechanic his whole life so the history of using this oil these ways has been well proven over time.

Decades old product that works!!!!
What can I say, this stuff never disappoints! There’s a reason your father and grandfather used it! It just plain works wonders in an engine or a gas tank. Got an old engine, give it a try!

Wow!
Silverado 5.3L had a lifter tick or just a mystery tick-either way this cured it & it’s been 3 months so I’d say it’s not just a temporary fix. FYI I tried a couple other additive “ remedies “ ….. this one actually worked. Just added the whole bottle then drove for 15 minutes & changed the oil. Tick was gone immediately. Shoutout to Derrick from VGG “ I don’t know what’s in it… it’s a mystery… stuff just works “UPDATE- engine failed…. still gets rid of lifter noise 🤪 …… I’m conflicted about it. It does work for lifter tick so I digress.

Marvel is always good
I always need a supply of Marvel. Sometimes for the chainsaw, sometimes for the fuel, sometimes for the car engine or lawnmower. I am never disappointed when I use it.

Excellent product
I put this in any small motor I’m working on. If you have an engine that is surging run this through the gas for about 30 minutes.

Old remedy still out doing its new competition
2003 Saturn Vue bought used and had some old fuel in it. This is something my dad used as I was growing up so I in turn bought it and satisfied with the purchase. Unlike seafoam where you dump the whole bottle; this you only need to dump about a 1/4 of the container with each tank fill up. I had a moment and dumped the whole thing. It didn't do any harm to the vehicle but is still burning off the oil 1/2 tank of gas later. Don't make that mistake; it stinks, literally! Instead of 4 uses; I only got one! My bad.
