Myself and other mechanics I've worked with have used it for over 30 years on tapered pipe fittings/hose and as far as I know I've never heard of any problems with it with diesel fuel, hyd. oil, engine oil, propane lines, etc. The main thing is wind it the right direction and start it a thread or two back so no bits of it get in the fuel or hyd. system.
