I have a couple of unopened cans of ATE "Super Blue" from the early 2000s sitting around, I'll accept bets that they test zero moisture when I open them some day. I'll video the whole thing.
There are so many wive's tales about the fluids and lubricants we have in our machinery. My favorite, (or least favorite), is that oil goes bad in the crankcase when a car is parked for a long time. Or that seals dry out in the engine from sitting. All parroted on the internet by people who have never revived a long sleeping engine or disassembled an engine, etc. It is true that gasoline goes bad in an ugly way from long time sitting.
Heat and stress kills seals, period. Not bathing in oil for years. There is a film of oil on even the top end of an engine that has sat for years. The front pulley seal on my F-250 Power Stroke just started leaking, that is a vehicle that does road trips pulling a trailer. I'll change it, no big deal. Seals are important, don't get me wrong. So is dry brake fluid but getting a tester was a game changer for me. No more guessing.
