I've been using this stuff in my 172 for the last four years. Has anyone out there had any problems with this stuff? I've been using it to prevent valve and ring sticking. It seems to have done that, but after reading about the FTC sueing the company that makes this stuff over a similar product (ZMAX)that they have been pushing in the automotive world, I have my doubts.
