Engine Oil and Filter Specifications
The heart of the 2012 Audi A6’s maintenance regimen revolves around the 2.0L 4-cylinder turbocharged engine. This engine is sensitive to oil quality and requires a synthetic formulation that meets specific Audi and Volkswagen oil quality standards. The recommended viscosity grades include 5W-40, 5W-30, 0W-40, and 0W-30, with all-temperature synthetic oil being the preferred choice for optimal performance. If a specific synthetic oil meeting the required standard is not available locally, you should select a viscosity grade suitable for the local climate and operating conditions.
The total oil capacity for the engine, including the filter replacement, is 4.9 quarts. This is a critical figure to note to avoid underfilling or overfilling. Proper oil levels are essential for the turbocharger, which relies on a constant supply of fresh oil for lubrication and cooling. After refilling, it is vital to check the oil level to ensure it is correct. The oil drain plug should be torqued to 22 ft/lbs to ensure a proper seal without damaging the threads. For filtration, the AMSOIL Oil Filter is a top recommendation, offering a filtration efficiency of 99 percent at 20 microns. This high-efficiency filter helps reduce engine wear by capturing small contaminants that would otherwise circulate through the engine. An alternative high-quality option is the MANN-FILTERS Oil Filter, which features premium media that often offers improvements over standard OEM-branded filters.
Transmission and Differential Fluids
The 2012 Audi A6 is often equipped with an automatic transmission that utilizes a specific fluid designation (0AW…VTF03). This transmission requires 8.5 quarts for a total fill and approximately 6.3 quarts for an initial fill during a fluid exchange. Maintaining the correct fluid level is crucial for the longevity of the transmission, as it handles the torque output of the turbo engine and manages shifts for smooth operation. AMSOIL 100% Synthetic CVT Fluid is recommended for these applications, providing exceptional metal-to-metal frictional properties that help the transmission run smoothly under load and in varying temperatures.
For the front differential, the lubrication requirement is 2.3 pints. The differential operates under significant stress, especially in performance driving scenarios or when towing. AMSOIL SEVERE GEAR® 75W-90 100% Synthetic Gear Lube is an excellent choice for this application. It contains friction modifiers specifically designed for limited-slip differentials and helps control thermal runaway, a common issue in high-performance gear applications. This fluid also protects against rust and corrosion, extending the life of the seals and gears within the differential assembly.
Coolant and Brake Fluid
Effective cooling system maintenance is vital for the CAEB engine, which runs hot. The coolant system capacity for this vehicle is 10 quarts. You can choose between AMSOIL Passenger Car & Light Truck Antifreeze & Coolant, a pre-mixed solution that protects all cooling system metals, gaskets, and hoses for up to 150,000 miles or 5 years, or AMSOIL Propylene Glycol Antifreeze and Engine Coolant for those who prefer to mix it themselves. The propylene glycol version offers a non-toxic alternative that greatly surpasses standards for metallic corrosion and erosion protection.
Brake performance must never be compromised. The 2012 Audi A6 requires a DOT 4 hydraulic brake fluid. AMSOIL DOT 3 and DOT 4 100% Synthetic Brake Fluid is formulated to provide a stable viscosity over a wide temperature range, ensuring consistent pedal feel and excellent ABS responsiveness. It resists boiling, which can lead to brake fade, and maintains its lubricating properties even after long periods of service, making it a superior choice for vehicles with advanced braking systems.
Seasonal Storage and Performance Additives
For owners who plan to store their vehicle for extended periods, using AMSOIL Gasoline Stabilizer is highly recommended. This additive helps keep fuel fresh for up to 12 months, protecting against varnish and gum buildup that can clog fuel injectors. It also fights ethanol corrosion, which is a common issue in stored vehicles. Additionally, AMSOIL Engine Fogging Oil can be used to coat internal engine components, providing a protective barrier against rust and corrosion during inactivity.
To maintain peak performance during normal operation, consider adding AMSOIL P.i.® Performance Improver. This gasoline additive is designed to restore fuel injectors to 100% flow rate after just one tank of fuel, which can help restore up to 14% horsepower and improve fuel economy. It also helps prevent carbon buildup and controls pre-ignition knock, ensuring the turbocharged engine runs smoothly and efficiently. For those who want to keep their vehicle looking pristine, AMSOIL Power Foam® Carburetor and Induction-System Cleaner and the AMSOIL Miracle Wash Waterless Wash and Wax Spray offer excellent cleaning and protection for both the engine bay and the exterior finish.
