How old is too old?

[Tx Jim]

I'm not so sure about that, but as far as oil goes, I'm mostly just a user. How do you know that is what happens?

I'm asking because maybe there is a business in that. If oil degrades by shearing into pieces, then we should be able to figure out how old the oil is by simply measuring the change in viscosity, right?
Does anyone do that? Does oil viscosity change as it ages?

I would like to read an oil analysis report that stated ""The chain of molecules that make up oil get sheared into pieces during use, which degrades the oil until it can no longer provide an adequate lubricating cushion between parts""!

I wonder how many hours of use it requires to accomplish this degrading of the oil??

If you want to go the the time, I'm sure Blackstone Labs, can explain in detail.

The trouble is that grandpas are still built like they’d used to be.
Meeting a grandma like her would be as useful as putting nitro methane in my four cylinder.

lol... She might kill you, but you'd die with a smile on your face!

More hours than you may want to wait. Like cold fusion, that will be great technology when it happens. Honestly though, maybe the shearing idea is just ahead of itself. It really would be great if and when someone figures out how to slice and dice oil molecules with some sort of mechanical process.

When that happens, we can begin to get some real recycling done & turn plastic back into gasoline by simply shearing those long plastic carbon chain molecules down to a burnable fraction. Not yet though. So far it is just good sci-fi.

It might happen, someday.... but first, there's a lot of important things on that to-be-invented list that need our attention right now.
