...The engine, transmission and differential on your car runs fine on oil...
Now I am confused, are you saying they were not designed for grease, better off with oil or both? What is it about my statement that seems to have offended you? Personally I would hope not to be so confrontational even if I had tried the mentioned product and found it lacking in some way. Are you wishing to go on record as saying that any oil has better reliability over a wider range of temps than a specific product made to permanently lube moving parts in a variable pitch prop with all the heating and cooling and associated condensation and icing? By the way, put 90w140 in your engine, 5w10 in your differential and straight 40w in your automatic transmission and then come back and we'll talk. I thought the idea of this thread was to see what works. You don't seem to trust me but I assure you it does work. I will be willing to give you some if you wish to prove it to yourself.I don't know where you came up with "they were designed for it".
Churchmouse, color me interested in your different mixes. Say, what do you change up in an all stainless gun vs. a cerakoted gun?

"The engine, transmission and differential on your car" are continually pressure, bath or splash fed oil. That is not the case with firearms and once the lube is displaced it is gone.
