I have repaired many fans, but some can't be gotten apart without destructive forces. On many fans, the blades can be removed by releasing a plastic washer under a rubber plug, often under a label on the side opposite the blades. There may be other washers in a particular order on the shaft.

I use a grease rather than oil. I try to use one that claims not to migrate. I think oil is too thin and will dry out quickly. I have found many ball bearing fans that either wore, or were improperly built, in which the shaft spins in the inner race, instead of making proper use of the bearings. These will not last long before more attention is needed.
