Premium Synthetic Motor Oil for Heavy Duty Applications

Royal Purple's API-Licensed Heavy Duty SAE 40 High Performance Synthetic Motor Oil is a fully synthetic product, unlike traditional motor oils derived from crude oil. This oil is designed to lubricate, clean, and efficiently cool engines. Motor oils come in various types, including conventional, synthetic, diesel, bio-based, hybrid (blends of conventional and synthetic), and recycled oils. The weight and viscosity of motor oil, as well as the additives used by manufacturers during the refining process, can vary.

This particular oil has an SAE 40 weight, meaning it has a single SAE viscosity rating of 40 at normal operating temperature. It is crucial to consult your vehicle's owner's manual to ensure that this is the correct weight of motor oil for your vehicle. As a fully synthetic oil, it does not contain any crude oil. Synthetic oils can be used as an alternative to motor oils refined from crude oil, often providing superior mechanical performance, including increased fuel efficiency and reduced engine wear at extreme temperatures. However, the complex production method means that synthetic oils can be more expensive than conventional motor oils.

Royal Purple Motor Oil combines premium base oils with proprietary additive technologies to create high-performance motor oils that optimize engine performance and provide superior protection. When upgrading to Royal Purple, no special procedures are necessary, as it is fully compatible with mineral or other synthetic oils. Royal Purple recommends waiting until the manufacturer's first scheduled oil change in new gasoline engines before upgrading to their product.

Royal Purple's API-licensed motor oil delivers superior protection and improves performance in both gasoline and diesel engines. It meets the API SN licensing requirements, as well as the ILSAC GF-5 and Dexos1 1 performance requirements. This oil offers several benefits, including:

1. Better Wear Protection: The advanced formulation helps to reduce engine wear, extending the life of vital components.
2. Increased Fuel Efficiency: The oil's superior lubrication properties can lead to improved fuel economy.
3. Better Protection of the Expensive Catalytic Emission System: The oil's compatibility with modern engine designs helps to protect the catalytic converter, a crucial component of the emission control system.
4. Improved Compatibility with Fuels Containing Ethanol: The oil is designed to work effectively with fuels that contain ethanol, ensuring optimal performance.
5. Superior Corrosion Protection: The oil's formulation provides enhanced protection against corrosion, helping to maintain the engine's integrity over time.
