Ok... so I took another fan which show magnetism to the coils when power is applied and assembled that one for testing.
The first tested fan turns at 120 RPM

The second tested fan turns at 200 RPM.

What could cause the reduction in RPM on the first fan ?

What grade of oil should be used in it and how much oil ?
