Engine Oil Specifications and Capacity
Ensuring the correct oil viscosity and capacity is critical for the health of the 2012 Mercedes-Benz S600’s 5.5-liter 12-cylinder engine (Engine Code 275.953 Y Turbo). This powerful twin-turbocharged engine demands a lubricant that can maintain film strength under the high stress of forced induction and variable driving conditions. AMSOIL 5W-40 FS 100% Synthetic European Motor Oil and AMSOIL 0W-40 FS 100% Synthetic European Motor Oil are formulated to meet the rigorous demands of these vehicles, offering superior wear protection and engine cleanliness compared to conventional oils.
For this vehicle, the recommended viscosity grades are 0W-40 or 5W-40, suitable for all operating temperatures. The engine oil capacity is 9.5 quarts when including a filter change. After refilling, it is essential to check the oil level to ensure it is within the proper range. When performing an oil change, the oil drain plug must be torqued to the manufacturer’s specification of 22 ft/lbs to prevent leaks or damage to the pan threads. Using high-quality synthetic motor oil allows for extended drain intervals and better protection against the buildup of sludge and deposits, which is crucial for maintaining the efficiency and performance of a V12 engine.
Transmission and Differential Maintenance
The automatic transmission in the 2012 S600 utilizes the Mercedes-Benz 722.6 series (specifically SL057). This 5-speed automatic transmission requires a fluid that can handle the complex shifting patterns and high torque outputs generated by the V12 powerplant. AMSOIL Signature Series Fuel-Efficient 100% Synthetic Automatic Transmission Fluid and AMSOIL OE Fuel-Efficient 100% Synthetic Automatic Transmission Fluid are formulated to withstand the rigors of this transmission, providing reserve protection during heavy use and preventing fluid breakdown at elevated temperatures.
The total fill capacity for the 722.6 transmission is 8.5 quarts. While the specific transmission filter recommendations were not listed in the current data, using the correct synthetic transmission fluid is a fundamental aspect of maintenance. A high-performance fluid helps protect against wear, sludge, and temperature-related problems, ensuring smooth shifts and extending the life of the transmission components. This is particularly important for a luxury sedan that may see a wide range of driving styles, from relaxed highway cruising to spirited driving on winding roads.
Cooling System and Fluid Maintenance
The cooling system for the 2012 Mercedes-Benz S600 has a capacity of 15.3 quarts. Maintaining the proper AMSOIL Passenger Car & Light Truck Antifreeze & Coolant mixture is vital for regulating the temperature of the twin-turbocharged engine and preventing overheating or freezing. AMSOIL Antifreeze & AMSOIL Propylene Glycol Antifreeze and Engine Coolant products are designed to meet and exceed original equipment manufacturer requirements. The Passenger Car & Light Truck Antifreeze & Coolant is a unique poly-organic acid (OAT) formulation that is phosphate, nitrate, nitrite, silicate, borate, and amine-free, making it compatible with all other antifreeze colors and safe for all cooling system metals.
For those who prefer a concentrated coolant, AMSOIL Propylene Glycol Antifreeze and Engine Coolant offers a powerful alternative. This concentrated formula allows for mixing with distilled water to create a custom solution that provides protection for up to 150,000 miles or 5 years in passenger cars. It greatly surpasses standards for metallic corrosion and erosion, ensuring that the cooling system remains free from rust and scale, which can otherwise lead to expensive repairs in a high-performance engine.
Brake and Power Steering Systems
The braking system on the S600 requires a fluid that maintains stability under the extreme heat generated during repeated stops and the high pressures required for effective stopping power. AMSOIL DOT 3 and DOT 4 100% Synthetic AMSOIL DOT 3 and DOT 4 100% Synthetic Brake Fluid is recommended for use with Mercedes-Benz specifications (such as MB Sheet 331.0). This fluid ensures excellent responsiveness with ABS and traction control systems, maintaining a stable viscosity across a wide temperature range. It is formulated to prevent boiling, which is critical for safety in high-performance driving scenarios.
Additionally, the power steering system benefits from AMSOIL 100% Synthetic Multi-Vehicle AMSOIL 100% Synthetic Multi-Vehicle Power Steering Fluid. This fluid is designed to reduce friction and keep seals soft to prevent leaks, which is a common issue in older luxury vehicles. It resists heat degradation, ensuring long fluid life and providing strong anti-wear protection. The formulation also allows for quiet operation, maintaining the serene driving experience expected from the S-Class.
