Maintaining the 2012 Mercedes Benz C63 AMG with its powerful 6.3-liter V8 engine requires premium lubricants designed to handle extreme thermal loads and high-revving performance. This high-performance sedan demands fluid specifications that meet rigorous European standards to ensure longevity and peak power delivery. Using the correct viscosity and chemical composition prevents premature wear on the engine, transmission, and cooling systems.

Proper fluid selection is critical for the 2012 Mercedes Benz C63 AMG to maintain its legendary handling and acceleration characteristics. The 6.3-liter naturally aspirated V8 engine produces immense torque and power, generating significant heat during spirited driving. Standard oils may break down under these conditions, leading to sludge formation and increased friction. AMSOIL synthetic lubricants are engineered to resist thermal breakdown, ensuring the engine remains protected even during track days or aggressive highway driving.
Engine Oil and Capacity Specifications
The engine in this model is a 6.3L 8-cylinder with the DOHC E engine code. For the oil change, the system requires 9 quarts of fluid when the oil filter is replaced. It is crucial to check the oil level after the refill to ensure the correct quantity is present, as underfilling can lead to inadequate lubrication. When performing the oil change, the oil drain plug should be torqued to 22 ft/lbs to prevent leaks or damage to the drain pan.
Owners have two primary viscosity options depending on their climate and driving style. The recommended oils are the AMSOIL 5W-40 FS and the AMSOIL 0W-40 FS. Both are formulated with a European-specification formula that features a precise blend of synthetic base oils and premium additives. These fluids are designed to handle the high shear forces inside the engine while providing excellent protection for camshafts, bearings, and other critical internal components.
Transmission Fluid and Differential Care
The automatic transmission in the 2012 C63 AMG utilizes the 7-speed speed-shift transmission system. Depending on the specific data card configuration, the transmission may be a 722.907 or a 722.930, and some units may include the reduced-friction code A89. The total fill capacity for the 722.907 system is 9.5 quarts, while the 722.930 system holds 7.5 quarts. Using a fluid like the AMSOIL Signature Series Fuel-Efficient 100% Synthetic Automatic Transmission Fluid or AMSOIL OE Fuel-Efficient 100% Synthetic Automatic Transmission Fluid ensures the transmission shifts smoothly and withstands the rigors of heavy use.
The fluid resists thickening in sub-zero temperatures and maintains its viscosity in extreme heat, preventing wear on the clutch packs and valve body. For the rear differential, the capacity is listed as 2.5 pints. While specific gear lube recommendations were not detailed in the source data, using a high-quality synthetic lubricant is standard practice for maintaining the durability of the limited-slip differential found in this performance model.
Cooling System and Brake Fluid Essentials
Maintaining the cooling system is vital for the longevity of the high-performance engine. The cooling system capacity is approximately 12.4 quarts. Owners can choose between the AMSOIL Passenger Car & Light Truck Antifreeze & Coolant, which comes as a pre-mixed 50/50 solution, or the AMSOIL Propylene Glycol Antifreeze and Engine Coolant, which is a concentrated fluid that must be mixed with distilled water. Both options are phosphate-, nitrate-, nitrite-, silicate-, and borate-free, ensuring they are safe for all cooling system metals, gaskets, and hoses.
The brake fluid recommendation for this vehicle aligns with Mercedes-Benz specifications HBH, suggesting the use of DOT 4 plus or equivalent. The AMSOIL DOT 3 and DOT 4 100% Synthetic Brake Fluid meets these requirements, offering a high boiling point and stable viscosity. This stability is crucial for ABS and traction control systems, which rely on consistent hydraulic pressure to function correctly during hard braking events.
Additional Maintenance and Protection
Beyond the essential fluids, the 2012 C63 AMG benefits from regular care of its power steering system and fuel quality. The AMSOIL 100% Synthetic Multi-Vehicle Power Steering Fluid helps keep seals soft to prevent leaks and resists heat degradation, extending the life of the steering pump. For fuel system maintenance, the AMSOIL P.i. Performance Improver Gasoline Additive can help restore fuel injectors to 100% flow rate, potentially restoring up to 14% of lost horsepower and improving fuel economy.
Additional products such as the AMSOIL Gasoline Stabilizer can be useful for seasonal storage, keeping fuel fresh for up to 12 months. For engine protection during long periods of inactivity, the AMSOIL Engine Fogging Oil can coat internal components to prevent rust. These supplementary products ensure that every aspect of the vehicle receives optimal care, from the engine block to the exterior paint.
