Truth. Although that test is really neat and everything it doesn’t represent much of what’s taking place in a working engine with added heat and contaminents playing a factor.

Royal Purple is great oil but for daily use a good synthetic should suit you fine. Frequent oil change intervels are more important than the brand of oil being used I’d say.
