Not always a good idea. Some have a synthetic lubrication which will turn into sludge if you add a non synthetic oil to it. You can sometimes get away with it on sleeve bearings particularly older fans. -- Best Regards: Baron.

From what I've seen, and from pre-emptively oiling fans before they could fail, very few fan makers provide much of any additional lubrication to the fan bearings. It's a rare fan that I've exposed the bearings on and found a chunk of grease in there. Of the fans I've rejuvenated by oiling, only a few were unresponsive to treatment or would not continue running. These were the cheapest of the cheap--all the rest continue to run perfectly. William

By that stage of the game, the fan's cheap worn out plastic bearings have so much slop, that nothing short of perhaps axle grease will fill the slop. |
