Best oil for long term storage??
Hello, I’m putting away approximately 20 nice glow engines into storage. The engines range from OS FP, AX, Thunder Tiger, and about 4 Moki Engines. Also about 4 Saito and Magnum 4 strokes.
I drenched them all in air took oil and Marvel Mystery oil. Is this a proper storage for them. ??
Thanks

Marvel Mystery or Air Tool Oil are basically a very light oil, mixed with a mineral spirits solvent . They have very little cling and often wash away more oil than they leave behind.
The ATF does at least tend to wet and cling better over the long haul.
There are other fogging and rust preventative type oils out there that will cling to the metal ,even vertical surfaces. The Corrosion X is but one type. LPS, even WD-40 are now making long term corrosion inhibiting oils. I use Mobil "Vactra" oil which is a very sticky oil that is made to protect and lubricate sliding machine surfaces.Made from long chain oil stock it feels a bit like STP but not as thick. This stuff really hangs on! It is not easy to find however in small quantities. It has also been recently superceeded but just about any "way oil" would work.
Another one, sold by Boeing Aircraft for corrosion protection in aircraft is called "Boeshield". Looks, feells and smells a lot like thinned "Cosmolene" as used by the military.

I use mineral dexron ATF mixed with a little Seafoam for my storage oil. This works well and nothing rusts plus the Seafoam and detergents in the ATF do a good job of breaking the carbon down.

Now that's a new one on me and could be used on a salad as well. Clarence Lee, long time engine guru, reiterated in a recent AMA Engine Clinic article that he had still found nothing better than ATF and Marvel Air Tool Oil mixed 50-50 for ARO and engine storage.

Why bother messing with mixing oils. ATF by itself is all you need. It’s loaded with detergents and corrosion inhibitors to help keep things clean and oxidation free.

I've relied on Marvel Mystery Oil as storage oil all my life and never had any problems storing any engines. and I've used it as storage oil on some fairly expensive (E production MGB and older MGA) engines and crankshafts.

YS recommended the lightest weight Mobil ! because it didn't attack their silicone diaphragms nearly as much as petroleum oil. Cheap ATF is great because its thin and doesn't dry up like many other oils do over time .Its hard to flush out all the corrosive residue but any effort is better than none.

Generally not, especially not any of the premix synthetics used with alcohol fuels. YS being the exception due to the silicone in their fuel system being affected by petroleum oils.
Many synthetics are water miscible and will create corrosion where moisture is present.Klotz warns against using their methanol pre-mix oil as an after-run oil.
