Engine Oil and Filtration Specifications
Powering the 2022 Audi RS5 is a twin-turbocharged 2.9-liter V6 engine. This powerplant generates substantial force and heat, necessitating an oil that can maintain viscosity and film strength under extreme conditions. The engine requires a viscosity grade of 0W-30 for all temperatures. When performing a service, the system holds a capacity of 8.0 quarts, including the oil filter change. It is crucial to ensure the drain plug is torqued to 22 ft-lbs and that the seal is replaced to prevent leaks. While the primary recommendation is the AMSOIL 0W-30 MS, if a synthetic oil meeting the specific Audi/Volkswagen quality standard is unavailable, a grade suitable for the local climate may be used as a temporary measure.
Filtration is equally vital. The RS5 benefits from the MANN-FILTERS Oil Filter, which offers improvements over standard equipment-branded filters. The high-grade media ensures contaminants are captured effectively without restricting oil flow, which is critical for the longevity of the variable geometry turbochargers and the timing chain system. Using the correct filter ensures that the engine oil remains clean, maximizing the interval between service and protecting critical internal components.
Transmission and Drivetrain Fluids
The RS5 is typically equipped with an 8-speed automatic transmission (Code 0D5). Maintaining this complex transmission requires a fluid that can handle the rapid shifts and high torque loads characteristic of the Quattro all-wheel-drive system. The total fill capacity for the transmission is approximately 9.1 quarts, though the initial fill is around 3.8 quarts. Actual capacity can vary between 3.6 and 4.0 liters (3.8 to 4.2 quarts) depending on the specific unit and temperature.
AMSOIL Signature Series Fuel-Efficient 100% Synthetic Automatic Transmission Fluid is recommended to withstand the rigors of heavy towing, elevated temperatures, and challenging terrain. It remains fluid in sub-zero temperatures, providing reserve protection during heavy use. For those seeking a cost-effective yet high-performance alternative, the AMSOIL OE Fuel-Efficient 100% Synthetic Automatic Transmission Fluid is also a valid option, offering excellent wear protection for the transmission components.
The rear differential in the RS5 is equipped with a limited-slip mechanism (Axle Code QQS). To ensure smooth operation and prevent clutch binding or excessive wear, AMSOIL SEVERE GEAR® 75W-90 100% Synthetic Gear Lube is the ideal choice. The capacity for the rear axle is approximately 2.1 pints. This gear lube contains friction modifiers specifically designed for limited-slip applications and helps reduce operating temperatures, extending the life of the seals and gears while controlling thermal runaway.
Cooling and Brake Systems
The cooling system for the 2022 Audi RS5 has a total capacity of 10.6 quarts. Effective temperature regulation is paramount for a twin-turbo engine, as overheating can lead to severe damage. The AMSOIL Passenger Car & Light Truck Antifreeze & Coolant is a phosphate-, nitrate-, nitrite-, silicate-, borate-, and amine-free formulation that protects all cooling system metals, gaskets, and hoses. This 50/50 pre-mix provides protection for up to 150,000 miles or 5 years. For those who prefer a concentrated product that requires mixing with distilled water, the AMSOIL Propylene Glycol Antifreeze and Engine Coolant offers protection up to 150,000 miles in passenger cars and light trucks.
Braking performance in a vehicle of this caliber must be consistent and responsive. The RS5 requires a hydraulic brake fluid that meets DOT 4 standards. AMSOIL DOT 3 and DOT 4 100% Synthetic Brake Fluid provides excellent ABS and traction-control responsiveness. Its stable viscosity over a wide temperature range ensures that the brake pedal feel remains consistent during aggressive driving sessions, preventing the loss of braking power due to fluid boil.
About the Vehicle
The 2022 Audi RS5 represents the pinnacle of the brand’s performance-oriented sports coupe and convertible lineup. Built on the MLB Evo platform, it shares its DNA with the high-performance models from the wider Volkswagen Group but receives significant tuning to distinguish it as an RS model. The heart of the vehicle is the 2.9-liter TFSI V6 engine, a development born from the collaboration between Audi and Lamborghini. This powertrain replaces the previous V8 in certain contexts, offering a more efficient power delivery while maintaining the exhilarating acceleration expected from the RS badge.
Drivers of the RS5 appreciate its dual nature. It is comfortable enough for daily commuting yet possesses the agility and power to dominate a track day. The 2022 model year continues to refine the interior technology and driver assistance systems, making the car more usable in various conditions. The standard Quattro all-wheel-drive system with a rear-biased torque distribution ensures that power is delivered effectively to the road, providing stability during cornering and traction in adverse weather. The design language retains the aggressive single-frame grille and sculpted body lines that give the RS5 a distinct, purposeful look.
Despite its robust engineering, the RS5, like many high-performance German vehicles, can benefit from proactive maintenance strategies. The twin-turbocharged V6 engine, while powerful, can be susceptible to carbon buildup on the intake valves, particularly in direct injection applications where fuel does not wash over the valves. Using a high-quality fuel additive can help mitigate this issue. Additionally, the high-performance nature of the vehicle puts significant stress on the braking system. Regular fluid flushes are essential to maintain the boiling points required for safety. Owners should also be aware that the 8-speed transmission and differential are precision components; using the correct synthetic lubricants prevents premature wear and ensures the smooth shifting characteristics the vehicle is known for. Finally, the cooling system must be kept in top condition to manage the thermal loads of the turbochargers, making the use of high-performance Antifreeze & Coolant vital for long-term reliability.
Additional Care and Protection
To keep the 2022 Audi RS5 in peak condition, AMSOIL offers a range of additional products. For seasonal storage, AMSOIL Gasoline Stabilizer helps keep fuel fresh for up to 12 months, preventing varnish and gum buildup. If the vehicle is being stored for an extended period, AMSOIL Engine Fogging Oil can be used to coat internal engine components and prevent rust. For performance enhancement, AMSOIL P.i.® Performance Improver Gasoline Additive can restore up to 14% horsepower and clean GDI fuel injectors. Regular washing with AMSOIL Miracle Wash and protection with Exterior Ceramic Spray will keep the vehicle’s paint looking pristine. For maintenance tasks, tools like AMSOIL Synthetic Multi-Purpose Grease and Heavy-Duty Degreaser can assist in keeping the vehicle clean and well-lubricated during servicing.
