Take a read on some of the old oil threads and you can see the technical answer your question, and have all the info you need about oil, and why royal purple is a subpar product, shown to harm engines, especially those with forced induction. The short answer, it's is a fair bit more expensive than competing oils, and FAR FAR inferior in wear protection, and basically all oil testing. It's not even in the top 30 synthetics, and even some dino's outperform it. They have also been caught in a heap of lies as well as a company.

Thanks for the insight, looks like I’ll switch to a less expensive, but better performing brand of oil.
