I have 3-in-1 oil for my 1992 Royal Anniversary Edition and my Supreme Electro Hygiene model 903. I am of course not the original owner, and the Electro Hygiene is running dry. It really needs it! The question I have is, how much do I put in each one? I do know where the fill tubes are. The Electro Hygiene is missing the cap for the tube though. I'd like to oil them both, since I doubt that they have been any time recently. Thanks for the help! -Mitchell
