I've done that with 100's of PC fans. Often they have a cap under the  
label which is necessary for the fan to work. You have to remove the  
label, and then remove the cap. After putting in the oil, replace the  
cap and label. I often replace the label with a piece of black  
electrical tape so I know I've been there before. While I am at it, I  
clean the blades, etc with window cleaner on a q-tip.

Recently I have been mixing the oil with some grease a friend who  
repairs large appliances gave me. It's a local product, so I can't  
tell you what the US equivalent is. I put in a drop of oil to get it  
moving and once I can spin the blades by hand, I add the oil/grease
