Does anyone use the Type 41 Aircraft Mineral oil in the H/A master cylinders set up for mineral oil? I read something about it a while back and I see Aircraft Spruce carries it. Here's something I copied & pasted about it -
AeroShell Fluids 4 and 41 are mineral hydraulic fluids; the latter has superior cleanliness characteristics and is the more widely used grade.
