That statement is in direct conflict with the maintenance instructions on my
older furnace. If my blower bearings run dry I don't have a functional
blower for very long. I have never noticed the smell of oil after doing my
yearly furnace tune-up. I think better advice would be to consult the
maintenance instructions on your own furnace.
The blower does not get hot ,it is before the fire, plus alot of regular
wires run to it. If your bearings are sealed and have no oil port you do
not oil, but if you have oil ports you oil. Bearings are never meant to
run dry, or they fail very early.

The bearings that don't need oiling are oil-impregnated. Somehow they
mix oil in with the metal bearing, and when the motor runs, the oil
seeps out. When the motor stops for a long time, most of the oil
soaks back into the bearing. Amazing what humans can think of.
