Stopping your squeaky blowers

[C2K]

I find that dripping 3 in 1 oil onto the spindle and allowing it to lubricate the bearings prevents the motor from squeaking for a long time.

I spend up to 3 hours a day commuting in my car each working day, so the fan gets some hours on the clock and it still takes over a year to come back. Second application lasts longer than the first.
