Eons ago, I had a crusty old A&P who had gotten his start working on Constellation and DC-6es. He told me to use Marvel Mystery Oil to prevent my valves from sticking.
Haven't had a sticky valve in 30+ years of C-85 operation. So mark me with an "A" as well.
Also works great as an elephant repellent. Since I started using it, I haven't had a single elephant in my hangar.
"B" can be valid, if you use too much of it. ISTR an NTSB report where the plane's oil tank was half MMO.....

I was told years or decades ago aviators purchased this stuff in 55 gallon drums. There must have been a reason they used this. It's a shame this reason died with these aviators. Why we need to share all we know so we can pass this down to the next generation and not make them learn all this over again.

I know a crop duster who uses it in his big old radial engine daily and has for many years. He and his mechnanic swear by it. His engines usually run a long time with few problems. Never a stuck valve. He has been at it for over 30 years.
At one point, Steve Bennett, formerly Great Plains Aircraft Engines, told me to use 25 % Marvel Mystery Oil with my 30 W oil in the VW.
