Remember that pH can only be tested in a water based solution. To check used
motor oil or WVO pH you need to take a small amount of oil and add some
water,
shake vigirously for a bit and then let the two liquids separate; oil on
top,
water on the bottom. Test the pH of the water to find out if the oil is
acidic
or basic.

PH testing is near
trivial. http://www.indigo.com/test-strips/ph-test-strips.html
Oil can mechanically fail. Oil pumped from the ground is modified with
plasticizers to get the desired viscosity, this means that the oil has a lot
of
long chain polymers in it, and these long chain polymers are subject to
a phenomenon known as 'shear back", where the polymers trapped between the
cam
and followers (for instance) can be mechanically broken, over time the oil
in
the engine loses viscosity.
Synthetic oils basic molecule is built in the lab, can avoid this, but try
writing to an oil company and start asking detailed question, you may wind
up
talking to a lawyer.
I once talked with an oil engineer/scientist at Shell oil in Houston, asked
what
the specific chemistry was of their oil, and he started to tell me, but
outran
my ability to understand what he was on about somewhere in the first or
second sentence..
