Hi Scotty, I had a failing radiator fan clutch on an old 1986 Porsche 928 and got some mineral oil from the RC hobby shop and injected. for the loss oil shown in photo and seems to work. How long does it last and have you ever done?

won't last long, I tried that years ago, but what the heck, see how long it lasts you

Thanks for quick reply. I actually used silicone diff oil #1000. not mineral oil. If it doesn't last, then I'll go electric.
