so the more I'm thinking about it, the more I'm thinking this may be OK for a non-pressurized system, but I'd hesitate to use it in anything pressurized (like power steering, where I had my issue)How much did you add?
I have a weeping output shaft seal on my transfer case and added 50ml just for kicks. Seems to have significantly slowed it down, so I might add another 25ml to see if it makes anymore difference.
