Why do you need to oil it? (and what is a "9 high velocity fan"?)
the blade is spinning slowly and "9 high velocity fan is a portable fan
It shouldn't need oiling, the motor ought to have good bearings. It might be a power problem, it might be dirt, it might be that the bearings are "done".
If you fell like it - take it apart and have a look at the motor & bearings - does the motor turn freely?
I had this situation recently and what Lemonie says is right - have a look at the wire connections to make sure they are sound (which mine was) and a squirt of WD40 helped to make the motor spin the fan. While I realise that WD40 isn't an oil, I was worried about using oil in case it shorted the mains as it dripped. I figured that my safety is all-important and if the fan is having difficulty I will simply throw it out. After 20 bucks is expensive but it is nothing compared to a fire - and, yes, my fan was new and the store wouldn't take it back - but that's life, sometimes...Good luck.
WD40 is light oil in light petroleum, it shouldn't be used in place of grease but it doe free things-up. L
