I'm trying to understand the difference between oxidation, thermal
breakdown, and flash point.
First, is "oxidation" and "thermal breakdown" the same thing?
Does a higher flash point mean that the oil will resist oxidation
better than an oil with a lower flash point?
I've also noticed that some of the best petro oils out there have a
higher flash point than some of the synthetics (example below). Does
that mean that some of the best petro oils are more resistant to
thermal breakdown than some synthetics? I have always been convinced
that synthetics stand heat much better than petro oils, am I wrong?
The below information is taken directly from the Mobil's website - I
didn't make the numbers up!
