The 3.0L 6-cylinder engine found in your 2012 Audi S4, identified by the CCBA engine code, is a turbocharged powerhouse that demands precise lubrication. Unlike standard naturally aspirated engines, the turbocharger generates extreme heat and rotational speeds that can degrade conventional oils quickly. The recommended AMSOIL 5W-40 MS 100% Synthetic European Motor Oil, 5W-40 FS, and 0W-40 FS formulations are designed with a European formula featuring a precise blend of synthetic base oils and premium additives. These fluids meet the stringent Audi and Volkswagen oil quality standards required for this vehicle. A full change requires 6.6 quarts of oil, including the WIX Oil Filter replacement. Proper oil capacity ensures the oil pump can maintain adequate pressure throughout the entire range of engine operating conditions.
The cooling system is equally critical for the longevity of the S4. With a coolant capacity of 11.7 quarts, the system is robust but requires a fluid capable of withstanding the high thermal loads generated by the turbocharged engine. The AMSOIL Passenger Car & Light Truck Antifreeze & Coolant is a 50/50 pre-mix that offers protection for up to 150,000 miles or five years. It is engineered to exceed OEM requirements, protecting all cooling system metals, gaskets, and hoses without the use of phosphates, nitrates, nitrites, silicates, borates, or amines. For those who prefer a concentrated solution, the AMSOIL Propylene Glycol Antifreeze and Engine Coolant offers a longer service life of up to 150,000 miles, though it must be mixed with distilled water to achieve the correct ratio.
Transmission health is vital for the driving experience, particularly with the 7-speed automatic transmission (0B5) common in this model. The fluid capacity for a total fill is approximately 7.9 quarts, with an initial fill of 7.1 quarts. The AMSOIL 100% Synthetic DCT Fluid is the recommended choice, offering outstanding wear protection and performance in both extreme heat and cold. It is specifically designed to prevent the shudder issues that can plague automatic transmissions over time. If your S4 is equipped with a manual transmission, the AMSOIL 75W-90 Manual Transmission & Transaxle Gear Lube provides excellent protection for brass synchronizers and features friction modification for smooth shifting.
Braking performance and steering reliability should never be compromised. The hydraulic brake system in the S4 requires a high-quality DOT 3 and DOT 4 fluid. The AMSOIL DOT 3 and DOT 4 100% Synthetic Brake Fluid provides stable viscosity over a wide temperature range, ensuring excellent responsiveness for the ABS and traction-control systems. For power steering, the AMSOIL 100% Synthetic Multi-Vehicle Power Steering Fluid helps reduce friction, keeps seals soft to prevent leaks, and resists the heat that leads to fluid degradation. This ensures quiet operation and responsive steering even after years of service.
The differential in the S4, specifically the rear axle (0B5), requires specialized lubrication to handle the torque transfer. The capacity for the rear differential is 1.9 pints. The AMSOIL 75W-90 Long Life 100% Synthetic Gear Lube is recommended here, offering high-load gear and bearing protection, resistance to rust and corrosion, and improved cold-weather shifting. Its formulation supports extended service intervals and better seal life, ensuring the drivetrain remains smooth and quiet. Using a dedicated long-life gear lube helps maintain the differential’s efficiency and reduces the frequency of fluid changes over the life of the vehicle.
About the Vehicle
The 2012 Audi S4 represents the peak of performance engineering from the German automaker’s B8 generation platform. This mid-size luxury sedan is distinguished by its distinctive B5-derived but refined styling and a powerful driving character that sets it apart from its more conservative counterparts, such as the A4. At the heart of this machine is the 3.0-liter V6 supercharged engine, a configuration that delivers substantial horsepower and torque figures, providing rapid acceleration that rivals sports cars of the era. The supercharger ensures that power is delivered linearly and immediately, without the lag often associated with turbocharged units, making the S4 an engaging car to drive on both highway stretches and twisty back roads.
Built on a foundation of aluminum-intensive construction and advanced chassis dynamics, the S4 offers a driving experience that balances comfort with sharp handling. The vehicle typically features Quattro all-wheel drive, a hallmark of the brand that provides superior traction in varying weather conditions and enhances stability during aggressive cornering. Owners of the 2012 S4 often praise the interior quality, which combines high-grade materials with driver-focused ergonomics. The car’s reputation is that of a sophisticated yet powerful daily driver, capable of carrying passengers in comfort while delivering spirited performance on demand. Its market position as a high-performance luxury sedan has secured it a dedicated following among enthusiasts who appreciate German engineering precision, robust build quality, and a driving dynamic that keeps the driver connected to the road.
