Royal Purple 0W-40 is aimed at drivers who need versatile, high-performance protection across wide temperature ranges: owners of performance cars, late-model gasoline or diesel vehicles that accept 0W-40 viscosities, and motorists who want a premium, API-licensed synthetic that’s compatible with existing oils. It’s also appropriate for vehicles used in towing, spirited driving, or regions with large seasonal temperature swings. As with any oil change, follow your vehicle manufacturer’s viscosity and service specifications and inspect seals if your engine has an existing high oil consumption issue.\u003c\/p\u003e\n\u003csection class=\"product-faq-snippet\"\u003e\u003ch3\u003eFAQ\u003c\/h3\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Is Royal Purple 0W-40 compatible with my current oil?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: Yes.
