The reason devices like these are not valid for testing motor oils lies in mis-application. First, these bearing and ball wear/load testers use bearing steel on bearing steel contacts. Engines are not made from bearing steel, so the metallurgy is not correct to an engine application. Second, none of these test devices simulate the by-products of combustion.

As you can see, designing an oil for a “test” versus designing and oil for an engine are two completely different things. A PhD chemist that headed Research & Development for ExxonMobil Chemical once said that, “the only test for an engine oil is an engine.” That is a very true yet costly and time consuming reality. When Joe Gibbs Racing sought out Lubrizol, the world’s largest additive supplier, it cost over $1 million in engines and nearly 1 year to develop the specialized formulations for their NASCAR racing engines. Imagine how much time and money is involved in developing a fuel efficient motor oil for commercial diesel trucks, yet the technology for the commercial diesel trucks does not apply to the formulations for a NASCAR racing oil
