Really?
OK if the oil said to be has polar compound anti friction add, and pass the timken machine flawlessly like Duralube Commercial, Does it have chlorinated parrafin?
How to detect it has chlorinated parrafin? mass spectrograph will do? [/quote]
Timken test is flawed for it does not put temperature into consideration.
Also: it can be easily manipulated to the infomercial (product seller's) advantage, citing a non-laboratory controlled, research quality test results.
Funny that no major car manufacturers and engineering body (SAE), which literally spent millions of dollars in engine lubrication and design research, would publicaly endorse the use of such product.
So, should you care about the product in your car? Well, it's your money, it's your car(engine) and ultimately, it's your call.
