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.

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.

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!

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.
