The best penetrating oil I've ever found is Aero-Kroil. A co-worker that had a side business overhauling turbochargers swears it's the best and even got Pratt & Whitney to start using it on their development engines. Can order it from Eastwood; some good hardware stores may have it. Can also order direct . . . do a google search for Kroil.
