I hate it when my hummingbirds get stuck valves. Have you ever done a wobble test on a hummingbird? I better get some of this MMO stuff right away.

The hardest part is carefully removing the feathery little valve cover. After that, as long as you have the tiny wobble test fixture (available from Aircraft Spruce here), then it's all over in 10 minutes.

But be careful. The last time I wobble tested a hummingbird, he poked my hand so hard that it drew blood. No problem though. I just rubbed a little Marvel Mystery Oil on it.

That?s OK because that would be doing the world a favor. I?m more concerned about the same person puting it into their bird feeder first.

Default Mmo

MMO=one part ATF, three parts solvent
Is that what you want in a engine or
Fuel tank?
It?s great for removing grease, oil or
A fastener removing fluid.
So no from me on any use on a
Engine related system.

Sorry meant to that they are chlorinated
And polar solvents.

I guess the para-dichlorbenzene is there as a perfume. Sniff away!


I have a legitimate use for MMO in my air tools. A professionally used air drill (In the early days) has had regular treatments since 1975 and still works well. It may have cancer though.

I don’t use MMO. However, solvents have a long history of being used as a carrier of lubricants, some even as lubricants.
Penetrating oil is an example. It has low viscosity due to the added solvents. It penetrates where oil alone would not be able to. Solvents lower flash points typically mean they don’t stick around long either.

My theory with MMO, Mouse Milk, etc....is the same with any oil rendered to a lower overall viscosity by a solvent. It will penetrate a tighter gap carrying some of the lubricant. It will also do some chemical scrubbing or dissolving of residue.

Other examples....
Some old timers would add kerosene to their Diesel swearing it helped keep injectors clean.
Kerosene also works well as a lubricant and coolant when machining aluminum by the way. (Not recommended due to its combustible nature, but we used it back in the day).

Solvents and lubricants have been married together for a long, long time. You’re going to have widely differing views on its effectiveness or potential risk of use in an aircraft engine.

Hi Jon, I agree entirely with your knowledgable post. I don?t use MMO either. At one time I tried to purchase some mouse milk for my Vetterman exhaust slip joints but it was classified as hazardous (flammable) material and could not be air-freighted to Australia. So I just made up my own brew with 50% automatic transmission fluid and 50% acetone. It seems to work quite well and may possibly be better than mouse milk in that application. As you say, you need a solvent carrier to allow the lubricant to wick into tight spaces. I wouldn?t use MMO in my fuel or engine oil but I must admit that if my plane will be sitting around without use for a month or so while I?m overseas then I put some Camguard into my oil before my last flight. But that might just be blind faith.
