Royal Purple 0W-40 Motor Oil

Motor oil is a crucial component of engine operation, derived from crude oil and used to lubricate, clean, and cool engines. The types of motor oil available include conventional, synthetic, diesel, bio-based, hybrid (blends of conventional and synthetic), and recycled oils.

The viscosity and weight of motor oil can vary, with some manufacturers adding specific additives during the refining process. The Society of Automotive Engineers (SAE) has developed a numerical code system to grade motor oils based on viscosity, with higher numbers between 0 and 60 indicating a more viscous (thicker) oil. Most consumer motor oils are graded with two numbers, where the first number represents cold weather (Winter or "W") performance.

For instance, an oil with an SAE rating of 0W-40 has a viscosity of 0 in cold temperatures and 40 at normal operating conditions. It's essential to consult your vehicle's owner's manual to ensure you use the correct motor oil weight for your specific make and model.

Synthetic motor oil, which does not contain crude oil, often provides superior mechanical performance compared to traditional motor oil. This includes increased fuel efficiency and reduced engine wear, especially at extreme temperatures. However, the complex production process may result in a higher cost for synthetic oil.

One premium synthetic motor oil option is Royal Purple, which combines high-quality base oils with proprietary additive technologies to optimize engine performance and provide superior protection. Royal Purple motor oil is compatible with both mineral and other synthetic oils, and no special procedures are required when upgrading from a different brand.

Royal Purple recommends waiting until the manufacturer's first scheduled oil change in new gasoline engines before switching to their API-licensed motor oil, which meets ILSAC GF-5 and Dexos1 performance requirements for both gasoline and diesel engines.

When transitioning to Royal Purple in high-mileage engines, it's recommended to run a minimum of two short (3,000 mile/5,000 km) intervals before extending the oil drain intervals. This allows Royal Purple's high solvency to gradually remove existing deposits, which can otherwise restrict oil flow and reduce the oil's service life.

Properly formulated synthetic oils, such as Royal Purple, generally do not cause engine oil leaks. However, if an engine has excessive oil consumption, it's recommended to address that issue before switching to a synthetic oil.

The key benefits of using a quality synthetic motor oil like Royal Purple include better wear protection, increased fuel efficiency, improved compatibility with fuels containing ethanol, and better protection for the catalytic emission system.
