Read the MSDS, Jon. It's about 30% petroleum oil. It is light weight
oil, so it may not be a superior long term lubricant, but it sure is a
useful short term lubricant. It also protectes againt rust pretty
effectively.

There are several things it should not
be used on, like bearings, or anything
that maintains a greased lubrication.

Sewing machine oil and electric motor
oil are far better lubricants for moving
parts.

Like all multi-purpose, multi-function
products, it may not do anything better
than single-purpose products.

I don't think I said anything that disagrees with that, Chuck. Sewing
machine oil is a poor choice if you use it for the wrong applications,
too. WD-40 has plenty of applications where it is a better choice than
sewing machine oil or electric motor oil. In fact, the WD40 company
realizes this, and also markets sewing machine oil and electric motor
oil under it's 3-IN-ONE brand.

Personally, and readily admitting to be a dilettante on the subject, I use
dry lubricants (McLube) on most exposed-to-weather surfaces that want
lubrication, rarely using WD-40 although I seem to always have several cans
on hand. I can't think of any application where I use light oil -- mostly
it's dry lube or one grease or another, depending upon the device.
