MOPAR doesn't make any fluids or filers, they have fluid specs and have MOPAR logo put on.
Royal Purple is as fine a product line as any lubricant company in existence. Their product performance has been proven in any number of tests readily available on GOOGLE and you tube and car/truck magazines.
Limited slip additives are only to prevent "shudder" and break down quickly.
