When it comes to the engine, the 2021 Mercedes Benz E63 AMG S with the 4.0L engine code 177.980.0 requires a robust oil change strategy. The oil capacity for this vehicle is 9.5 quarts when including the filter change. It is crucial to use a viscosity that matches the environmental conditions; the engine accepts 0W-30 and 0W-40 for all temperatures, as well as 5W-30 and 5W-40 for temperatures above -25°C. The AMSOIL FS (Fluid Shock) technology in these European formulations provides superior engine cleanliness and viscosity control, which is vital for the longevity of the turbochargers and the complex lubrication needs of the variable valve timing system. After refilling, always check the oil level to ensure accuracy. For the oil drain plug, ensure you torque the plastic plug to 3 ft/lbs or the metal plug to 22 ft/lbs to prevent leaks or damage.
Cooling system maintenance is equally critical for this high-output engine. The cooling system capacity varies based on the configuration, with the LTCC requiring 6.8 quarts and the HTCC requiring 16.1 quarts. AMSOIL coolants are phosphate-, nitrate-, nitrite-, silicate-, borate-, and amine-free, ensuring compatibility with all other antifreeze colors and materials. They protect the cooling system metals and gaskets against corrosion, which is essential for preventing overheating during spirited driving. Whether you choose the pre-mixed Passenger Car & Light Truck Antifreeze & Coolant or the concentrated Propylene Glycol Antifreeze and Engine Coolant, you gain protection that exceeds original equipment manufacturer requirements.
The transmission in this vehicle is a vital component that handles immense power. While specific fluid recommendations for the transmission filter are not available, the fluid itself is crucial. The AMSOIL Signature Series Fuel-Efficient 100% Synthetic Automatic Transmission Fluid provides the necessary reserve protection during heavy use and abuse, ensuring the transmission remains fluid and responsive. Alternatively, the AMSOIL OE Fuel-Efficient 100% Synthetic Automatic Transmission Fluid offers excellent protection against wear. Both options help maintain the transmission’s efficiency and longevity, even under severe driving conditions.
Brake fluid maintenance is often overlooked but is essential for the safety and performance of your E63 AMG S. The vehicle requires a DOT 4 plus fluid, and the AMSOIL DOT 3 and DOT 4 100% Synthetic Brake Fluid is an ideal replacement. It provides excellent ABS and traction-control responsiveness and maintains stable viscosity across a wide temperature range, complying with MB Sheet 331.0 requirements. This ensures your braking system remains reliable and responsive when you need it most.
For vehicle owners who engage in seasonal storage or want to maintain peak fuel system performance, AMSOIL offers additional protective products. The AMSOIL Gasoline Stabilizer helps keep fuel fresh for up to 12 months, preventing varnish and gum buildup. The AMSOIL P.i.® Performance Improver can restore up to 14% horsepower and clean GDI fuel injectors to 100% flow rate after just one tank of fuel. These additives, along with the Upper Cylinder Lubricant Corrosion Inhibitor, help maintain engine efficiency and prevent carbon rap. For exterior care, products like the AMSOIL High-Foam Car Shampoo and Exterior Ceramic Spray provide lasting protection against the elements while keeping the vehicle looking pristine.
About the Vehicle
The 2021 Mercedes-Benz E63 AMG S represents the pinnacle of the E-Class sedan lineup, combining everyday luxury with supercar performance. Part of the W213 generation, this model is powered by the legendary M177 4.0-liter twin-turbocharged V8 engine, a masterpiece of German engineering. This engine, often referred to as the “Biturbo,” is known for its incredible torque output and responsiveness, capable of propelling the heavy sedan to 60 mph in seconds. The “S” designation indicates the high-performance iteration of the E63, featuring enhanced cooling systems, upgraded suspension components, and a more aggressive exhaust note compared to the standard E63.
Owners of this vehicle appreciate its dual personality. It serves as a practical, four-door luxury cruiser that can comfortably carry passengers and cargo on a daily basis, yet transforms into a track-capable machine when driven enthusiastically. The interior is typically appointed with high-quality materials, advanced MBUX infotainment, and supportive sports seats. The drivetrain usually features an all-wheel-drive system with a selectable “Race” mode that allows the driver to adjust power distribution for maximum traction or rear-wheel bias for more dynamic handling. This blend of comfort and raw power has cemented the E63 AMG’s reputation as one of the best performance sedans in its class.
However, the extreme conditions these vehicles operate under can take a toll. Common issues include the potential for oil consumption due to the high-stress environment of the turbochargers and piston rings, especially over long periods of high-performance driving. Additionally, the complex cooling system can be susceptible to leaks or degradation if the AMSOIL Propylene Glycol Antifreeze and Engine Coolant quality is not maintained, leading to overheating risks. The transmission, while robust, can suffer from fluid breakdown if subjected to constant hard launches or track use without adequate AMSOIL Signature Series protection. Furthermore, brake fade can be a concern after repeated hard stops, making the use of high-quality AMSOIL DOT 3 and DOT 4 100% Synthetic Brake Fluid essential to maintain consistent pedal feel and performance.
Using AMSOIL synthetic lubricants addresses these specific challenges directly. The synthetic motor oil’s superior thermal stability helps mitigate oil consumption issues by maintaining a consistent film thickness even under extreme heat. The specialized coolants prevent the corrosion and buildup that leads to cooling system failures. The high-performance transmission fluid ensures smooth shifting and protects internal components from the wear caused by aggressive driving. Finally, the synthetic brake fluid provides a higher boiling point than standard fluids, reducing the likelihood of fade during spirited driving. By investing in these premium products, owners can enjoy the full potential of their E63 AMG S with greater confidence and longevity.
