Please advise me.

What kind of oil should I use for a 1/3 hp electric motor?

The motor bearings have oil ports.

Can't I just use regular automotive motor oil? Would gear oil be better?

It's the fan motor for my electric furnace (squirrel cage). The original
1/3 hp motor blew up. The furnace guy insisted I put a 1/4 hp motor in,
but the capacitor blew and the 1/4 hp motor blew up. I had a surplus 1/3
hp motor I bought. It turned in the wrong direction so I reversed the
stator. It worked ok all last winter but I want it lubed up for next
winter. The biggest problem is keeping the wires away from the fan blades
because the stator is reversed, but I've got them tied back pretty good.

I've used this for years on just about anything that needed it, including my
furnace blower motor, which is now 15 years old.
The extendable spout is quite handy.
