Ken, 

I really appreciate you sending me the picture. That was really nice of you
to take the time to try and help educate me.

however, I don't see the air going through any oil. I assume that there is
oil in the bottom of the filter, or else the gauze is saturated with oil,
but the diagram doesn't show a reservoir of oil coming up above the intake
tube. Or, am I not seeing it?

I just took another look at the two pictures. The oil in the light duty
filter is shown by light broken lines. The heavy duty filter has the same
lines but the level is below the bottom of the intake tube.

I suspect that the main difference between light and heavy duty is that in
the light duty the air goes through the "gauze" first, and in the heavy duty
filter the air goes through the much thicker layer of "gauze" after it has
hopefully dropped its dust into the oil.

What do you think/
