The 2016 Audi S8 is a high-performance luxury sedan powered by a 4.0L 8-cylinder twin-turbocharged engine, identified by the engine code DDTA L. This powerhouse requires precise lubrication to handle the intense thermal and mechanical stress generated during both daily commuting and spirited driving. Because the engine is turbocharged and operates at high RPMs, the AMSOIL 5W-40 MS 100% Synthetic European Motor Oil must provide exceptional shear stability, rapid flow in cold temperatures, and superior protection against high-temperature sludge buildup.
For the 2016 Audi S8, AMSOIL offers a range of 100% synthetic European motor oils designed to exceed the specific Audi and Volkswagen oil quality standards required by this vehicle. Whether you prefer the flow characteristics of the AMSOIL 0W-40 FS 100% Synthetic European Motor Oil for colder climates or the high-temperature stability of the AMSOIL 5W-40 FS, there is a fluid tailored to your driving conditions. The engine requires 9.2 quarts of oil when changing the filter, and the oil drain plug must be torqued to 15 ft/lbs with a new seal.

Proper lubrication extends beyond just the engine. The transmission system in the 2016 Audi S8, specifically the 8-speed automatic (0BK), requires fluid that can handle rapid shifts and heavy loads. The initial fill capacity is approximately 3.8 quarts, though a total fill requires about 9.1 quarts. Using the AMSOIL Signature Series Fuel-Efficient 100% Synthetic Automatic Transmission Fluid ensures smooth operation and prevents the degradation that can lead to slipping or harsh shifting. Similarly, the differential lubrication is critical for the all-wheel-drive system to ensure power is distributed efficiently and quietly. The front and rear differentials each hold 1.9 pints of AMSOIL 75W-90 Long Life 100% Synthetic Gear Lube, making a full synthetic 75W-90 the ideal choice for high-mileage durability.
Fluid maintenance also includes the cooling system, which holds 15.9 quarts of AMSOIL Passenger Car & Light Truck Antifreeze & Coolant. This vehicle requires an antifreeze that does not contain silicates, borates, phosphates, or nitrites, which AMSOIL Propylene Glycol Antifreeze and Engine Coolant formulations achieve through their advanced OAT chemistry. This compatibility ensures that the cooling system components remain free from corrosion and deposit buildup, preserving the integrity of the aluminum components typical in modern Audi engines. Additionally, the brake system and power steering require specific DOT 4 synthetic AMSOIL DOT 3 and DOT 4 100% Synthetic Brake Fluid and multi-vehicle AMSOIL 100% Synthetic Multi-Vehicle Power Steering Fluid to maintain the high safety standards and handling precision expected of a performance sedan.
To further protect this high-value investment, adding a fuel system cleaner like AMSOIL P.i. Performance Improver can restore up to 14% horsepower and clean fuel injectors. For seasonal storage, AMSOIL Gasoline Stabilizer and AMSOIL Engine Fogging Oil prevent internal rust and fuel degradation when the vehicle is not in use for extended periods. These additives ensure that every aspect of the vehicle’s operating systems remains protected, from the fuel intake to the brakes and suspension components.
Vehicle Background
The 2016 Audi S8 represents the pinnacle of the S8 lineage, blending supercar performance with the comfort and luxury of a full-size sedan. Built on the Audi A8 platform, this vehicle features a 4.0-liter TFSI twin-turbo V8 engine, a powertrain that has been a hallmark of Audi’s high-performance models. The engine delivers substantial horsepower and torque, allowing the S8 to accelerate from 0 to 60 mph in just over three seconds, despite its heavy curb weight. This performance is managed by a sophisticated Quattro all-wheel-drive system, which provides excellent traction in all weather conditions, making it a capable choice for year-round driving.
Owners of the 2016 S8 appreciate its dual nature as a practical daily driver and a track-capable machine. The interior is appointed with the highest quality materials, including leather and aluminum trim, creating a serene cabin environment that belies the engine’s explosive power. The vehicle was designed to compete with other luxury performance sedans, offering a smooth ride that isolates occupants from road imperfections while maintaining sharp steering feedback. As a successor to the legendary V10 models, the S8 established the twin-turbo V8 as a modern benchmark for efficiency and power in the luxury segment. Its reputation for engineering excellence means that regular maintenance with high-quality lubricants, such as AMSOIL motor oil and AMSOIL transmission fluid, is essential to keep the complex components, including the twin turbos and air suspension, functioning at peak performance for years to come.
