I have oiled mine with a very light machine oil, but then I did the same with my radio controlled helicopters back in the 80's. a fine dropper (hypodermic ) needle was used. Many folk leave them to run dry but i find my 501ss's noisy. I think a lot depends on how dusty the environment is (take off and landing) as to if people find lubrication helpful or not.
