Engine Oil and Capacities
The heart of the 2023 E63 AMG S is its 4.0L 8-cylinder turbo engine, identified by engine code 177.980 C. This powerplant requires a lubricant that can handle extreme combustion temperatures and high shear forces. AMSOIL motor oils are designed to blow the doors off the highest industry standards, offering protection that keeps the engine running smoothly for the long haul.
For this specific engine, the oil capacity is 9.5 quarts when including the filter change. After a refill, it is critical to check the oil level to ensure proper lubrication coverage. When replacing the oil drain plug, pay close attention to the torque specifications to prevent leaks or damage to the drain pan threads. For metal drain plugs, apply 22 ft/lbs of torque, while plastic drain plugs require a much gentler 3 ft/lbs. Always replace the drain plug seal to maintain a perfect seal against oil leaks.
Both the AMSOIL 5W-40 FS and 0W-40 FS are excellent choices, with the 0W-40 offering broader temperature coverage and the 5W-40 providing optimal viscosity for temperatures above -25°C. These European formulas feature a precise blend of synthetic base oils and premium additives designed specifically for the unique demands of modern European vehicles, including hybrids.
Transmission and Differential Fluids
The transmission system in the E63 AMG S is subjected to significant stress, especially during rapid acceleration and gear shifts. Using a properly formulated transmission fluid protects the transmission from wear, sludge, and temperature-related problems, allowing you to drive with confidence. While no specific filter recommendations are available for this transmission, the fluid choice is paramount.
For the automatic transmission, the AMSOIL Signature Series Fuel-Efficient 100% Synthetic Automatic Transmission Fluid (ATL) stands out for its ability to withstand heavy use and abuse. It remains fluid in sub-zero temperatures and provides reserve protection during heavy towing or challenging terrain. The AMSOIL OE Fuel-Efficient 100% Synthetic Automatic Transmission Fluid is also a recommended alternative that protects against wear effectively.
Regarding the differential and transfer case, the E63 AMG S features a specific setup. The transfer case capacity is noted as 1.5 pints, with a torque specification of 18 ft/lbs for the drain plug and 10 ft/lbs for the fill plug. The front differential requires 1.3 pints, while the rear differential capacity is 2.5 pints. While the source indicates that specific filter recommendations for these areas are not available, ensuring the correct lubricant fill levels and types is essential for the longevity of the drivetrain.
Cooling and Brake Fluid Systems
Maintaining the correct coolant is vital for the cooling system, which manages the intense heat generated by the twin-scroll turbocharger. The E63 AMG S has specific coolant capacities: 6.8 quarts for the LTCC (Low Temperature Cooling Circuit) and 16.1 quarts for the HTCC (High Temperature Cooling Circuit). AMSOIL Passenger Car & Light Truck Antifreeze & Coolant is a phosphate-, nitrate-, nitrite-, silicate-, borate-, and amine-free formulation that protects all cooling system metals, gaskets, and hoses. It is an ethylene glycol 50/50 pre-mix that exceeds OEM requirements and offers protection up to 150,000 miles or 5 years.
For the braking system, safety and responsiveness are non-negotiable. The E63 AMG S requires brake fluid that meets Mercedes-Benz Sheet 331.0 specifications. AMSOIL DOT 3 and DOT 4 100% Synthetic Brake Fluid is an ideal choice, providing excellent ABS and traction-control responsiveness. It maintains a stable viscosity over a wide temperature range, ensuring consistent pedal feel and stopping power even under the most demanding driving conditions.
Additional Protection and Maintenance
Beyond the essential fluids, there are several additional products that can enhance the performance and protection of your 2023 Mercedes-Benz E63 AMG S. The AMSOIL P.i.® Performance Improver Gasoline Additive is designed to restore up to 14% horsepower and bring GDI fuel injectors back to 100% flow rate after just one tank of fuel. It helps prevent carbon buildup and reduces the need for costly higher-octane fuel, making it an excellent addition for a direct injection turbocharged engine.
For vehicle owners who keep their cars for extended periods or engage in seasonal storage, AMSOIL Gasoline Stabilizer helps keep fuel fresh for up to 12 months, protecting against varnish, gum buildup, and ethanol corrosion. Additionally, AMSOIL Engine Fogging Oil can be used to protect internal engine components during long periods of inactivity, preventing rust and corrosion on cylinders and rings.
For exterior and interior care, AMSOIL Synthetic Multi-Purpose Grease offers outstanding low-temperature pumpability and high load-carrying performance for chassis components. The AMSOIL Heavy-Duty Metal Protector provides a long-lasting, protective coating against rust and corrosion from salt and moisture.
