Proper lubrication extends the life of your vehicle by minimizing wear on critical components. The engine oil in your ML63 AMG must withstand high temperatures and shear forces while maintaining viscosity to protect internal parts. Similarly, the transmission fluid must handle the torque of the 6.3-liter V8 without losing its frictional properties. By choosing AMSOIL, you ensure that every fluid system is optimized for the specific engineering requirements of your Mercedes-Benz.
Engine Oil Specifications and Capacities
The heart of your 2009 Mercedes-Benz ML63 AMG is the 6.3-liter V8 engine (Engine Code DOHC E). Maintaining the correct oil level and viscosity is paramount for this high-output powerplant. The oil capacity for the 6.3L engine, including the filter, is 10.2 quarts. It is important to note that on models equipped with an oil cooler, additional oil may be required if the cooler is drained during service. Always allow five minutes after refilling or turning the engine off before checking the oil level to ensure an accurate reading. When draining and refilling, tighten the oil drain plug to a torque of 22 ft/lbs to prevent leaks or damage to the pan.
Transmission Fluid and Differential Lubricants
The 2009 ML63 AMG is equipped with a 7-speed automatic transmission (722.9). Depending on the specific configuration of your vehicle, you may have the standard friction settings or a reduced-friction code (A89) on your data card. In either case, the total fill capacity for the 7-speed 722.9 transmission is 9.7 quarts. Using a fluid that meets or exceeds the OEM SL057 or SL058 specifications is crucial for shift quality and transmission health. AMSOIL Signature Series Fuel-Efficient Automatic Transmission Fluid is engineered to withstand the rigors of heavy towing, elevated temperatures, and challenging terrain, providing a reserve of protection during heavy use and abuse. Alternatively, the OE Fuel-Efficient Automatic Transmission Fluid offers strong protection against wear and is suitable for standard maintenance intervals.
Cooling System and Brake Fluid
A cooling system flush is an essential part of maintaining the health of your ML63 AMG. The system requires 12.2 quarts of antifreeze and coolant. AMSOIL Passenger Car & Light Truck Antifreeze & Coolant is a 50/50 pre-mix formulation that is phosphate-, nitrate-, nitrite-, silicate-, borate-, and amine-free, ensuring compatibility with all other antifreeze colors and protecting all cooling system metals, gaskets, and hoses. For those who prefer a concentrate, AMSOIL Propylene Glycol Antifreeze and Engine Coolant offers ultimate flexibility, providing protection up to 150,000 miles or 5 years and surpassing metallic corrosion standards. This formula is compatible with all other antifreeze colors and free of the harsh additives found in traditional coolants.
Braking performance is non-negotiable for a vehicle of this caliber. For the ML63 AMG, AMSOIL DOT 3 and DOT 4 100% Synthetic Brake Fluid is the recommended choice. It provides excellent ABS and traction-control responsiveness, ensuring your stopping power remains consistent. The fluid maintains stable viscosity over a wide temperature range, which is vital for safety in both winter driving and high-speed maneuvers.
Power Steering and Seasonal Maintenance
Whether your ML63 AMG features a belt-driven power steering pump or an electro-hydraulic pump, proper fluid is essential for quiet operation and seal health. The vehicle requires power steering fluid that meets Mercedes-Benz specifications (MB sheet 236.3 for belt-driven systems or 345.0 for electro-hydraulic systems). AMSOIL 100% Synthetic Multi-Vehicle Power Steering Fluid is formulated to reduce friction, help seals remain soft to prevent leaks, and resist heat for long fluid life. It offers excellent high-temperature protection and low-temperature performance, ensuring the steering system operates quietly and efficiently.
For seasonal storage, protecting the fuel system and internal components is key. AMSOIL Gasoline Stabilizer helps keep fuel fresh for up to 12 months, fighting ethanol corrosion and preventing varnish and gum buildup. If the vehicle will be sitting for an extended period, AMSOIL Engine Fogging Oil is an effective rust preventive designed to protect internal engine components. Additionally, for vehicle owners looking to improve fuel system performance, AMSOIL P.i. Performance Improver Gasoline Additive can restore up to 14% horsepower and clean GDI fuel injectors back to 100% flow rate after just one tank of fuel.
