Exposing the Engine Oil Bearing Friction Test / Scam

I’ve come across a couple of engine oil / oil additives companies that use the timken bearing test – also sometimes known as the “one arm bandit” test or bearing lubricity test – to display the efficacy of their oil or oil additive. I must admit that the test, being very visual, is extremely convincing. But did you know that this non-standardised test is practically useless in demonstrating the efficiency of oils? In fact, it can actually be (unscrupulously) manipulated.

So, the next time before you’re convinced of the “superiority” of any engine oils or oil additives using this demonstration, remember this – you might actually be better off using shampoo*!!

*on the bearing test only please. Do NOT use shampoo in your engine!

    1. As this is a personal blog, my resources are pretty limited. Unfortunately, I’m unable to review too many products. The reviews you see on this website are stuff that I actually purchased and used. Perhaps if you would you be interested in sponsoring? 😉
