Understanding the specific fluid capacities and specifications for your 2008 Audi R8 is critical for maintaining its engineering integrity. The engine oil capacity for the 4.2L 8-cylinder engine is 10.6 quarts when the oil filter is included. It is vital to ensure the oil you select meets the applicable Audi and Volkswagen oil quality standards listed for this vehicle. While the engine is designed to run on viscosities such as 5W-40, 5W-30, 0W-40, and 0W-30 depending on the season and climate, the recommended AMSOIL options provide the necessary performance envelope for all temperatures. After refilling the oil, always check the oil level to ensure it is at the correct mark, and torque the oil drain plug to 7 ft/lbs to prevent leaks or damage to the threads.
The cooling system of the Audi R8 requires careful attention due to its complex design and capacity requirements. The system holds approximately 24.3 quarts of AMSOIL Passenger Car & Light Truck Antifreeze & Coolant. This formulation allows for use in a wide variety of vehicles while protecting all cooling system metals, gaskets, and hoses. For those who prefer a concentrated solution, AMSOIL Propylene Glycol Antifreeze and Engine Coolant offers a high-performance alternative that requires mixing with distilled water. Both options are phosphate-, nitrate-, nitrite-, silicate-, borate-, and amine-free, ensuring compatibility with all other antifreeze and coolant colors while providing protection against corrosion for up to 150,000 miles or 5 years.
Transmission service is equally important for the manual gearbox found in this vehicle. The manual transmission fluid capacity is 8.5 pints for the transmission case, though capacities vary slightly with the cooler system installed. For a case with a cooler, the empty capacity is 7.4 pints, and the full capacity with the transmission cooler is 1.9 pints. Using AMSOIL 75W-90 Manual Transmission & Transaxle Gear Lube ensures outstanding protection against the increased heat and pressure generated during high-performance driving. This fluid is friction-modified for excellent seal compatibility and includes rust inhibitors. Additionally, the differential lubricant for the front differential requires GLSC8 grade fluid with a capacity of 2.7 pints. AMSOIL 75W-90 Long Life 100% Synthetic Gear Lube is specifically designed for high-load gear and bearing protection, improving cold-weather shifting and extending service intervals significantly.
Brake and power steering fluids are often overlooked but play a crucial role in vehicle safety and handling. The Audi R8 specifies a DOT 4 hydraulic AMSOIL DOT 3 and DOT 4 100% Synthetic Brake Fluid, which exceeds these requirements. It provides a stable viscosity over a wide temperature range, ensuring excellent responsiveness for ABS and traction-control systems regardless of driving intensity. For the power steering system, AMSOIL 100% Synthetic Multi-Vehicle Power Steering Fluid reduces friction and helps seals remain soft, preventing leaks and resisting heat for long fluid life. This fluid is formulated for quiet operation, maintaining the smooth and precise steering feel that owners of the R8 expect.
About the Vehicle
The 2008 Audi R8 stands as a defining moment in the history of modern supercars, representing the marque’s ambitious entry into the exclusive world of mid-engine sports cars. Powered by the naturally aspirated 4.2-liter V8 engine developed from the Lamborghini Gallardo’s powertrain, this vehicle bridges the gap between everyday drivability and track-focused performance. The engine code BYH X signifies a specific iteration of this robust powerplant, known for its smooth power delivery, high-revving nature, and distinctive auditory character.
