The 2007 Mercedes-Benz S65 AMG is a high-performance luxury sedan powered by a 6.0L twin-turbo V12 engine (code 275.98.5). This powerful powerplant, capable of delivering substantial horsepower and torque, places unique demands on the lubrication system that standard mineral oils simply cannot meet. The extreme heat generated by the turbochargers and the high-compression nature of the V12 require a synthetic fluid that maintains viscosity and protects against wear under severe operating conditions. Using the correct AMSOIL synthetic lubricants ensures that every moving part—from the camshafts to the transmission gears—receives the protection needed for longevity and peak performance.

Engine Oil and Filtration Requirements
The heart of the 2007 Mercedes-Benz S65 AMG is the 6.0-liter M275 12-cylinder engine. This is a masterpiece of automotive engineering, but it is also a complex machine that operates at high pressures and temperatures. The engine oil capacity for this vehicle is 9.5 quarts including the filter. 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. When refilling, it is recommended to allow five minutes after turning off the engine before checking the oil level to ensure accuracy. The oil drain plug requires a torque setting of 25 ft/lbs.
While the source data indicates no specific oil filter recommendations are currently available for this vehicle in the AMSOIL database, using AMSOIL 5W-40 FS or AMSOIL 0W-40 FS 100% synthetic motor oil effectively compensates for the lack of a specific filter recommendation by reducing soot and sludge formation. The FS designation stands for Formula Synthetic, which implies a precise blend of synthetic base oils and premium additives tailored for gasoline, diesel, and hybrid European vehicles.
Transmission and Drivetrain Protection
The transmission in this vehicle is a critical component that requires fluid specifically matched to its internal tolerances. For the 722.6 transmission found in the S65 AMG, the total fill capacity is 8.5 quarts, with an initial fill of 6.9 quarts. Regular maintenance is vital here, as the transmission fluid not only transmits power but also lubricates gears and cools internal components.
AMSOIL Signature Series Fuel-Efficient 100% Synthetic Automatic Transmission Fluid is a top recommendation for this application. It is engineered to withstand heavy towing, elevated temperatures, and challenging terrain while remaining fluid in sub-zero conditions. This ensures that the transmission shifts smoothly and that the clutches engage properly without slip. For owners seeking a slightly more economical option that still meets high-performance standards, the AMSOIL OE Fuel-Efficient 100% Synthetic Automatic Transmission Fluid provides excellent wear protection and fuel efficiency.
While the source summary does not list specific differential or transfer case fluids for the S65 AMG, it does note a rear capacity of 4 pints for differential lubrication. Ensuring this area is protected with high-quality gear lubricant is essential for the vehicle’s handling and rear-end durability.
Cooling and Fluid Maintenance
Proper cooling system maintenance is non-negotiable for a vehicle with a twin-turbo V12. The AMSOIL Passenger Car & Light Truck Antifreeze & Coolant capacity for the 2007 S65 AMG is 12.5 quarts. The cooling system protects the engine from overheating, which is a primary cause of failure in high-performance engines. AMSOIL offers two excellent options: a pre-mixed formula that is a phosphate, nitrate, nitrite, silicate, borate, and amine-free formula that protects all cooling system metals, gaskets, and hoses for up to 150,000 miles or 5 years. Alternatively, the AMSOIL Propylene Glycol Antifreeze and Engine Coolant is a concentrated formula that offers protection for up to 150,000 miles or 5 years in passenger cars, or even longer in heavy-duty applications.
In addition to engine and transmission fluids, the braking system requires attention. The S65 AMG uses DOT 4 fluid. AMSOIL DOT 3 and DOT 4 100% Synthetic Brake Fluid is an ideal replacement, offering excellent responsiveness for ABS and traction control systems. It resists boiling and maintains viscosity across a wide temperature range, ensuring consistent pedal feel. Similarly, the power steering system benefits from AMSOIL 100% Synthetic Multi-Vehicle Power Steering Fluid, which helps seals stay soft to prevent leaks and resists heat for long fluid life.
About the 2007 Mercedes-Benz S65 AMG
The 2007 Mercedes-Benz S65 AMG represents the pinnacle of luxury and performance during its production year. As the flagship model of the S-Class lineup, it combines the opulent comfort of a limousine with the raw power of a sports car. The vehicle is defined by its monstrous 6.0-liter V12 biturbo engine, designated as the 275.98.5. This engine produces a staggering amount of power, typically in the 600 to 620 horsepower range, delivering over 700 lb-ft of torque. This immense force is sent to the rear wheels through a robust 5-speed automatic transmission, which was specifically calibrated for the heavy weight and high output of the vehicle.
Driving the S65 AMG is a unique experience. On the highway, it acts as a silent, floating cruiser, absorbing road imperfections with ease. However, engage the accelerator, and the character changes instantly. The twin turbochargers spool up quickly, and the sheer acceleration pushes the driver back into the seat. The vehicle is a grand tourer in the truest sense, capable of traveling vast distances at high speeds while providing a serene interior environment. The exterior styling of the 2007 model features aggressive AMG-specific elements, including unique front and rear fascias, side skirts, and larger alloy wheels that distinguish it from standard S-Class models.
Despite its reliability, the S65 AMG does have known issues that owners should be aware of. The high-output twin-turbo V12 can be prone to oil consumption if the vehicle is driven hard over long periods, making a high-quality synthetic oil like AMSOIL FS essential to minimize wear and maintain levels. The carbon buildup on the intake valves is a common problem in direct injection or high-temperature engines, which can be mitigated with the use of AMSOIL P.i. Performance Improver gasoline additive to restore injector flow and clean the fuel system. Additionally, the complex cooling system requires frequent checks, as any failure can lead to catastrophic engine damage due to the high thermal loads. Finally, the rear suspension air springs, common on this platform, can develop leaks over time, but regular maintenance of all fluid systems helps ensure the air system and chassis control remain functional for years.
Owners of the 2007 S65 AMG understand that this vehicle demands the best. Using AMSOIL synthetic lubricants is not just a maintenance choice; it is a commitment to preserving the performance and longevity of one of the most impressive cars ever produced. Whether you are driving to a track day or a long-distance cruise, these specialized fluids ensure that every component operates within its optimal parameters.
