Diesel RVs: Re: [diesel_mercedes] Max Age WVO - WAS Re: [CARS-ETC] What's up with U.S. gasoline prices?

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..

(sigh)

oil testing, for standard, is about 10 bucks, here.
but, they don't test for PH. dang.

I've run 20 gals of WMO through the centrifuge, and run it in my
truck.....works great. I diluted with diesel, before "spinning" to thin it
for better effect. And thinned again in the tank, since it had diesel
already in it.

I'm told, "oil" never wears out, only the additives and junk that gets in
it.
So, one might imagine given a good enough cleaning, PH balancing, and new
additives, it could run a long time.

Well, that is very interesting. One of the questions in their FAQ is whether
it would be practical to centrifuge and re-use motor oil., they think
perhaps so if using synthetic motor oil...
I recall reading somewhere (Diesel Power?), of an aftermarket diesel filter
that contained an additive package booster. As the used oil becomes
contaminated with acid the PH goes to hell and starts eating expensive bits,
this package neutralizes that.. I do wonder if you had an synthetic oil
who's viscosity wasn't dependent on long chain polymers, might not be used
forever with this combination... How much is oil testing, nowadays?
