Ensuring the 2012 Mercedes-Benz ML63 AMG performs as intended requires a rigorous adherence to the manufacturer’s fluid specifications, particularly given the demanding nature of its 5.5-liter twin-turbocharged V8 engine. The unique engineering of the AMG lineage places high thermal and mechanical stress on lubricants, making standard synthetic blends insufficient for optimal protection and longevity. Owners of this vehicle need lubricants that can withstand extreme temperatures, resist thermal breakdown, and maintain viscosity under heavy loads to preserve the integrity of the drivetrain and engine components.

Proper lubrication is critical for the longevity of the ML63 AMG, a vehicle known for blending high-performance capabilities with luxury utility. The engine requires specific oil changes to manage the heat generated by its twin-scroll turbochargers. Using the correct viscosity and fluid composition ensures that moving parts remain separated by a protective film, reducing friction and preventing the premature wear that can occur in high-stress environments. The cooling system also demands a specialized fluid to prevent corrosion within the aluminum cooling passages and to maintain optimal operating temperatures, which is essential for a vehicle that pushes its limits on the road or track.
Engine Oil and Fluid Capacities
The 5.5-liter V8 engine in the 2012 ML63 AMG has specific fluid requirements that must be met during every service interval. For the engine oil, the recommended viscosity grades are either 0W-40 or 5W-40, suitable for operation across all temperature ranges. The total oil capacity is 9 quarts, including the filter replacement. When performing an oil change, it is crucial to refill the system and then check the oil level to ensure it is accurate. Proper torque specifications are vital during the drain plug installation; the M12 bolt requires 15 ft/lbs, while the M14 bolt requires 22 ft/lbs. No specific oil filter recommendation is currently listed for this vehicle, but using high-efficiency filtration is a standard practice for maintaining engine health.
The cooling system requires a significant volume of fluid, with a total capacity of 12.4 quarts. Owners can choose between a pre-mixed ethylene glycol coolant or a concentrated propylene glycol version, depending on their preference for storage and mixing. Both formulations are designed to be compatible with all coolant colors and free from phosphates, nitrates, and silicates, which protects the integrity of gaskets, hoses, and metals within the cooling system. This ensures that the engine operates efficiently without the risk of scaling or corrosion that can plague older cooling systems.
Transmission fluid is another critical component for this vehicle, with variations depending on the specific transmission code found in the vehicle’s data card. For models equipped with the 7-speed automatic transmission code 722.931 (with or without the A89 Reduced-Friction code), the total fill capacity is 7.5 quarts. For those with the 722.905 transmission code, the capacity is either 7.5 or 9.5 quarts depending on the specific configuration. In these applications, AMSOIL synthetic automatic transmission fluids are designed to withstand heavy towing, elevated temperatures, and challenging terrain. They remain fluid in sub-zero temperatures and provide reserve protection during heavy use, ensuring smooth power delivery and long-term transmission durability.
For those who engage in extended storage, seasonal products play a vital role in preserving the vehicle’s integrity. AMSOIL Gasoline Stabilizer helps keep fuel fresh for up to 12 months, protecting against varnish and gum buildup caused by ethanol corrosion. This is ideal for vehicles that sit idle during the off-season. Additionally, AMSOIL Engine Fogging Oil is a highly effective rust preventive designed to protect internal engine components during long periods of inactivity, making it an excellent choice for safeguarding the engine before winter storage or extended trips.
Differential and Transfer Case Lubrication
The transfer case and differential systems in the ML63 AMG require specialized lubrication to handle the torque distribution and load-bearing demands of an all-wheel-drive performance SUV. For the transfer case, the capacity varies by configuration. Double-speed transfer cases require 3.2 pints, while single-speed configurations need 1.1 pints. For the front differential, the capacity is 1.7 pints. While specific gear oil recommendations for these components are not always listed in standard fitment guides, maintaining these lubricants is essential for the longevity of the drivetrain. Using high-quality synthetic fluids helps ensure that the gears are adequately lubricated, reducing wear and preventing the friction that can lead to premature failure in these high-performance components.
Brake fluid is another critical safety component that must be replaced regularly. The ML63 AMG utilizes a DOT 4 system, and AMSOIL DOT 3 and DOT 4 100% Synthetic Brake Fluid is recommended to maintain peak braking performance. This fluid offers excellent ABS and traction-control responsiveness, ensuring that the braking system reacts quickly and predictably in emergency situations. The stable viscosity over a wide temperature range helps prevent brake fade, keeping the vehicle safe and controllable regardless of driving conditions. Regular replacement of brake fluid is essential to prevent moisture absorption, which can lower the boiling point and lead to a spongy pedal feel or reduced stopping power.
