Trying to understand what these mean.

[Chris B.]

Kind of new here and I wondering what some of these terms mean.

What does it mean when oil shears?

What is volatility?

What is flash point?

Also I kind of understand viscosty, that is how thick or thin the oil is right?
Feel free to add any other terms but these are all I can think of now. Many thanks!!

Thanks for the link!

I did not find Shear in it though.

Shearing--simply stated, the oil is "sheared" down to a lighter viscosity:
