Maintaining the high performance of your 2016 Audi S6 requires more than just standard maintenance intervals; it demands fluids specifically formulated to handle the rigors of a twin-turbocharged 4.0L V8 engine. The CTGE E Turbo engine generates significant power and heat, placing exceptional stress on lubricants and coolants. Using the wrong viscosity or a fluid that fails to meet strict Volkswagen/Audi standards can lead to reduced fuel economy, increased wear, and potential damage to sensitive components like the turbocharger and the sophisticated 7-speed dual-clutch transmission (S tronic). Proper lubrication ensures that metal surfaces remain separated, heat is managed efficiently, and the vehicle’s sophisticated electronics, such as the ABS and traction control systems, function reliably.

The engine in the 2016 Audi S6 is a marvel of modern engineering, featuring a 4.0-liter V8 with twin turbochargers. This powertrain is designed to deliver immense horsepower and torque, but it also generates substantial heat. The oil must resist thermal breakdown to maintain its protective film between moving parts. The recommended oil capacity for this engine, including the filter change, is 9.2 quarts. It is critical to use an AMSOIL 5W-40 MS 100% Synthetic European Motor Oil or AMSOIL 5W-40 FS that meets the specific Audi and Volkswagen quality standards; otherwise, the longevity and performance of the engine could be compromised. Whether you are navigating city traffic or pushing the car on a track, the right viscosity grade helps manage the stress placed on the turbocharger bearings and the rest of the engine components. If you are looking for AMSOIL 0W-40 FS 100% Synthetic European Motor Oil, it is also an excellent choice for ensuring proper flow.
Transmission and Drivetrain Protection
The 2016 Audi S6 is equipped with a sophisticated 7-speed S tronic dual-clutch transmission (model 0B5). This transmission is complex and sensitive, requiring a fluid that can handle rapid shifts and extreme heat generated during aggressive driving. The total fill capacity for a complete flush is 7.9 quarts, though the initial fill is approximately 5.8 quarts. Using a fluid that does not meet the OEM specifications can lead to shudder, harsh shifting, and premature wear of the clutch packs. AMSOIL 100% Synthetic DCT Fluid is formulated to prevent these issues, ensuring the transmission operates smoothly and efficiently, even under the most demanding driving conditions. Maintaining this fluid is as crucial as changing the engine oil, as transmission failures are often costly and can ruin the driving experience of this high-performance sedan.
Beyond the powertrain, the differential and braking systems also play a vital role in the vehicle’s performance. The front differential holds approximately 2.1 pints, while the rear differential requires about 1.9 pints of lubricant. These limited-slip differentials benefit from a high-quality synthetic AMSOIL 75W-90 Long Life 100% Synthetic Gear Lube that resists shear and provides excellent extreme pressure protection. The braking system relies on DOT 3 and DOT 4 hydraulic fluid, which must maintain stability to ensure the anti-lock braking system (ABS) and electronic stability programs function correctly. AMSOIL DOT 3 and DOT 4 100% Synthetic Brake Fluid offers a high resistance to moisture absorption and a high boiling point, preventing brake fade and ensuring consistent pedal feel.
Cooling System and Maintenance
The cooling system for the 2016 Audi S6 holds a capacity of 15.9 quarts of AMSOIL Propylene Glycol Antifreeze and Engine Coolant. Keeping the engine at the optimal temperature is essential for performance and reliability. A high-performance antifreeze like AMSOIL Passenger Car & Light Truck Antifreeze & Coolant ensures that the engine does not overheat under load, nor does it freeze in cold weather. This fluid is free of phosphates, nitrates, and silicates, making it safe for all cooling system metals and hoses. For owners who prefer a concentrated solution, the Propylene Glycol Antifreeze offers a long-lasting option that can be mixed to the desired ratio. Proper cooling system maintenance not only protects the engine block and head but also ensures that the cabin heater works effectively when needed.
