I assume I need to oil something but I'm not sure what and what type

Any suggestions?

When my last furnace started "squeaking"

squirrel cage, literally coming apart at
the welds. * It started like a
sizzling/squeaking sound, but then,
after some time, it got very loud and
annoying. *I was able to replace the
blower squirrel cage to fix the

My old clunker had oil cups on the blower and oil ports on the motor,
newer stuff is sealed bearings you cant oil. Maybe a loose belt. I
think any oil is good, except cooking oil, although once as a kid I
put mazola in the mower. Oil if you can but sound going away sounds
like a belt if you have one.
