I am about to do my first oil change on my 2006 Honda and purchased a Fumoto valve to replace the drain plug and make future oil samples and changes easier. Since the Fumoto is a permanent replacement for the oil plug, I was concerned that after a long time and many pounding miles, it might get loose. I have used teflon tape many times to make sink, bathroom and other water/hose type connections and was wondering if putting a wrap or two on the Fumoto threads would do any good. I am also concerned about the teflon tape and the high heat in the oil pan. I do not want it to break-down and swirl in my oil. Has anyone used a teflon tape wrap on their oil plug before? I would not bother with this at all except the Fumoto will be there from now until I get rid of the truck.
