That is not what I would put on drain , level and fill plugs. That's what they make crush washers for. If anything I would use & have used Loctite 518, a red jell comes in a tube. Used on orings for fuel tank pump plates in Aprilia's. I put it on rubbers on early Stelvio's that fit through the bodywork. Also I have put it on petcock retaining nuts to stop a drip. Works great.
