"Muggles"

I've tried various oils for this over the years
and the one I found that works is snowmobile
chain case oil that contains graphite. Now
when the fan is turned off the blades coast to
a stop like a pedestal grinder. And the motor
runs cooler too when running for hours on end.

Snowmobile chain case oil? Would that be the
same oil people might use
on chain saws?

No. Chain saw bar oil is a high film strength oil.
The fan may not even turn with this oil... ;)}
Graphite is a lubricant even when dry.
