the blower motor bearings since most of the time you don't get much effect from trying this. I've used a spray lube for woodworking router bit bearings that worked for awhile on some dying BMW blower motors. This stuff has a tiny tube that comes with the spray can, works for awhile .
Sandaro Bearing Lubricant is the name. Very small 2.5oz spray cans. Would be great if blower manufs. gave you sealed ball bearing equipped motors that you could replace the bearings on instead of the whole assembly. Always seem to use the "oilite" or bronze type set-up.
