I needed my 7" fan for something else (They don't seem to sell 7" AC
fans these days.) so I got out one of my father's fans for use at the
computer. It's a Bersted 1250R "Zero" model, made by McGraw Hill in
the 50's they say.
1) I couldn't find my regular oil, so is there any reason not to use
10W-30? It never gets that cold in the house, especially in the summer
when I use a fan, so I figure that's 30 weight. Good enough, right?
2) So that leaves the detergents. They're not something that actually
has any effect at room temperature, are they? I figure they work when
the oil in the car is hot. (How hot is that?)
3) Then the fan made some noise, and it was clearly from the metal
blades, not the armature. Is there any way I can stop the noise from
the blades? Could I tie them to the protective screen, for example?
Mine looks a lot better than this one, and has the original cord.

Hmmm. Well, too late now. We'll see.
Actually, the noise the fan made was something out of a Tennessee
Willaims story, with a fan in the background in 1930's bar or pool room,
or a lawyer's office. But it stopped making the fin noise after 3 or 4
minutes and the only noise was the air moving. It only has one speed,
which is a little too high since it's 2 feet behind my head.
The prior cheap newish plastic fan had two speeds, but by coincidence,
one just broke. I'm going to try putting it in the laundry chute, to
blow basement air to the second floor.

It doesn't give the viscosity. It really should, but maybe they're
afraid if they do that, more people will do what I do.
I bought one of these about 20 years ago. When it's empty I fill it up
with 30 weight motor oil. And if I could have found that quickly, I
would have used that, Last I looked, all 3 zoom bottles, 30, 10W-30,
and one refilled with Liquid Wrench, were in the same place, but not
