It is backward-compatible with mineral and other synthetics, meets API SN, ILSAC GF-5 and Dexos1 performance expectations, and is suitable for many gasoline and light-duty diesel applications. No special flushing or procedures are required when switching, though Royal Purple suggests waiting until the manufacturer’s first scheduled oil change in a new gasoline engine before upgrading.\u003c\/p\u003e\n\n\u003ch3\u003eHow does Royal Purple 5W-20 help protect my engine during stop-and-go driving?\u003c\/h3\u003e\n\u003cp\u003eThe proprietary additive system builds a protective film that reduces metal-on-metal contact, which is especially helpful in urban and short-trip driving where frequent starts and idling can increase wear. That improved wear protection helps maintain engine components over time and can preserve performance under everyday stress.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eAdvanced anti-wear additives to limit component abrasion\u003c\/li\u003e\n  \u003cli\u003eStable viscosity for consistent lubrication in varied temperatures\u003c\/li\u003e\n  \u003cli\u003eCorrosion inhibitors that protect internal surfaces from moisture and acids\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWill switching to Royal Purple 5W-20 improve fuel economy?\u003c\/h3\u003e\n\u003cp\u003eRoyal Purple’s synthetic base stocks and friction-reducing chemistry are designed to lower drag inside the engine, which can translate to small but measurable fuel-efficiency gains under normal driving.
