Recommended Oil Viscosity for GLC 63 S AMG

When it comes to choosing the right oil for your Mercedes-AMG GLC 63 S, it's essential to consider the recommended oil viscosity. Oil viscosity refers to the thickness or fluidity of the oil. It is denoted by a number followed by "W," which stands for winter, and another number indicating the oil's viscosity at normal operating temperatures.

Mercedes-Benz recommends using synthetic oils since they provide superior performance, protection, and longer service life for high-performance engines like the one in your GLC 63 S AMG.

Understanding Oil Viscosity Ratings

The Society of Automotive Engineers (SAE) classifies oils based on their viscosity at different temperature ranges. The first number before the "W" indicates the oil's viscosity during cold starts, while the second number indicates the viscosity at normal operating temperatures.

For the GLC 63 S AMG, Mercedes-Benz suggests using an oil viscosity of 0W-40 or 5W-40. These oils offer optimal performance and protection, especially in start-stop driving conditions and extreme temperature environments.

Benefits of the Recommended Oil Viscosity

Choosing the recommended oil viscosity for your GLC 63 S AMG provides several benefits:

• Improved Cold Start Performance: Smaller WSAE numbers (e.g., 0W) indicate a thinner oil during cold starts, enabling it to flow quickly and lubricate vital engine components, reducing wear and tear.
• Enhanced High-Temperature Stability: The second number in the oil viscosity rating (e.g., 40) indicates its resistance to thinning at high operating temperatures. A higher number ensures adequate lubrication and protection in hot environments.
• Lower Fuel Consumption: The use of recommended oil viscosity reduces internal friction within the engine, resulting in improved fuel efficiency and performance.
• Extended Engine Life: The proper oil viscosity maintains optimal film strength between moving parts, minimizing metal-to-metal contact, and reducing engine wear, leading to increased engine life.

Consult Your Owner's Manual and Professionals

While the recommended oil viscosity for the GLC 63 S AMG is typically 0W-40 or 5W-40, it is crucial to always consult your vehicle's owner's manual for precise recommendations. The owner's manual will provide detailed information on the specific oil requirements for your exact model and year of production.

If you are uncertain or have any doubts, it is recommended to consult with a professional technician or contact your Mercedes-Benz dealership. They have the expertise and knowledge to guide you in selecting the correct oil viscosity for your GLC 63 S AMG.

Remember, using the recommended oil viscosity and adhering to the recommended oil change intervals will optimize the performance, reliability, and longevity of your GLC 63 S AMG's high-performance engine.
