Ensuring the 2012 Mercedes Benz CL65 AMG receives the proper lubrication is critical for maintaining the performance and longevity of its powerful 6.0L twin-turbocharged V12 engine. This vehicle operates under extreme thermal and mechanical stress, particularly in the high-speed, high-torque environment typical of the AMG line. Using fluids that meet or exceed the strict German engineering standards of the manufacturer is essential for preserving valve train life, protecting the complex turbocharger bearings, and ensuring smooth operation of the 5-speed automatic transmission. Whether it’s extending the time between AMSOIL 5W-40 FS changes or protecting against extreme temperatures, synthetic motor oils will keep your CL65 AMG protected. We produce the synthetic motor oil, oil filter, transmission fluid, gear lube and grease for a complete fluid change – everything to keep your Mercedes Benz CL65 AMG running smoothly for the long haul.

The engine is the heart of this performance machine, and it requires careful attention to oil capacity and change intervals. For the 2012 CL65 AMG equipped with the 6.0L 12-cylinder engine (Engine Code 275.982 5 Turbo), the oil capacity is 9.5 quarts when including a filter change. It is vital to check the oil level after refilling to ensure the correct level is maintained. The oil drain plug torque specification is 22 ft/lbs, a critical detail during service to prevent leaks or damage. Whether you choose the 5W-40 or 0W-40 viscosity, the European formula ensures your V12 engine receives the necessary lubrication to handle the immense pressure of its twin-turbo setup.
Moving beyond the engine, the cooling system requires a fluid capable of managing the intense heat generated by the supercharged engine bay. The coolant capacity for this vehicle is 14.7 quarts. AMSOIL Passenger Car & Light Truck Antifreeze & Coolant is a pre-mixed glycol-based solution that protects against corrosion without the need for phosphates, nitrates, or silicates, ensuring long-term compatibility with the vehicle’s cooling components. For those who prefer mixing their own, the propylene glycol concentrate offers protection up to 1,000,000 miles in heavy-duty applications, though for this passenger vehicle, the 150,000-mile or 5-year limit applies.
The transmission in this high-performance coupe is a 5-speed automatic unit (722.6….SL057). Proper fluid selection here is not just about shifting smoothness; it is about preserving the complex clutch packs and hydraulic systems from the heat generated during spirited driving or track use. A total fill for this transmission requires 8.5 quarts. The AMSOIL Signature Series Fuel-Efficient 100% Synthetic Automatic Transmission Fluid is engineered to withstand extreme temperatures and heavy loads, while the OE Fuel-Efficient version provides a reliable alternative that protects against wear and maintains fluidity in cold weather. Both options help prevent the sludge and temperature-related problems that can lead to costly transmission failures. Using a properly formulated transmission fluid can protect your vehicle from costly problems down the road.
Fluids for Safety and Maintenance
Brake fluid maintenance is essential for the safety of the CL65 AMG. The manufacturer recommends using DOT 4 plus or products approved on MB Sheet 331.0. AMSOIL DOT 3 and DOT 4 100% Synthetic Brake Fluid provides a stable viscosity across a wide temperature range, ensuring that your anti-lock braking system and traction control function reliably when you need them most. For the power steering system, which relies on specific lubrication for smooth operation, the 100% Synthetic Multi-Vehicle Power Steering Fluid helps seals remain soft to prevent leaks and offers strong anti-wear protection against high-temperature breakdown.
About the Vehicle
