Marvel Mystery Oil

[Goober]

Back in the 40's / 50's, there was an option to install a Marvel Mystery Oiling system on cars. Basically, there was a large can under the hood that held the oil and a vacuum push type pump switch inside the car under the dash. Every once in a while you pushed the buttom and injected some oil into the engine. If you can find one of these kits, the old car restorers love them. Saw one on Ebay go for over $200.00 one time. If fact, go here and look

John: Marvel Mystery Oil is the aviator's best friend, at least those than live with engines that have those cylindrical sluminum things with rings on them moving up and down. Larry can confirm that, especially when it's storage time or loosening sticky valves. Add a pint to the oil, fire up the engine to circulate the stuff and shut it down. Does a great job for protecting against corrosion to prevent valves from hanging up in the guides. Z-max--AvBlend--does the same thing. Even more. It doesn't burn off like Marvel Mystery Oil. Even so, if there's a valve-sticking problem, pour in a can of Marvel Mystery Oil. But to prevent valve sticking plus coat the crank journals and cylinder walls, cry once and use Z-max or, in case of an airplane, Avblend.

Remember Mr X, aka Ralph P. He would soak Merlin (Packard) cranks in heated Avblend before assembling engines. Expensive, but consider how much that V12 cost!

Yes, Marvel Mystery oil is good in the gas, too. It truly is a marvel. But it's not in the same league with Avblend. Compare prices.
