The 2012 Jaguar XKR-S with its formidable 5.0L supercharged V8 engine demands a level of fluid precision that matches its high-performance engineering. This vehicle is not a standard sedan; it is a grand tourer built for spirited driving and high-speed capability. To maintain the integrity of the DOHC D engine code and ensure optimal performance across all operating conditions, owners must prioritize the use of lubricants that exceed standard factory specifications. Using the correct viscosity, meeting the precise capacity requirements, and selecting the right filtration systems are critical steps in preserving the longevity of this luxury sports car.

Understanding the specific fluid needs of your Jaguar is the first step toward maximizing its service life. The 2012 XKR-S represents a peak in Jaguar’s engineering, combining luxury with track-ready performance. The 5.0-liter V8 engine, designated by the DOHC D code, produces significant power and torque. Because of the immense heat generated by the supercharged engine, standard mineral oils can break down under such stress. Synthetic motor oil is not just a luxury here; it is a requirement. It provides superior thermal stability, ensuring that the oil maintains its viscosity even during high-speed runs on the track or spirited driving on winding roads. The oil capacity for a full change, including the filter replacement, is 7.7 quarts. Ensuring you have the correct quantity of the right viscosity, 5W-20 for all temperatures, is vital for proper lubrication of the camshafts and piston rings.
Maintaining the Cooling and Transmission Systems
The cooling system on the XKR-S is designed to handle the thermal load of a high-output engine. With a capacity of 14.6 quarts, the coolant plays a massive role in maintaining engine temperature. AMSOIL offers both pre-mixed and concentrated antifreeze options that meet or exceed OEM requirements. The pre-mixed version saves time and eliminates the error of improper water-to-coolant ratios, while the concentrated version allows owners to mix their own to specific ratios for extreme climates. Both options provide protection against corrosion, gasket hardening, and hose degradation, ensuring the cooling system remains leak-free for years.
Similarly, the transmission is a critical component that requires precise fluid dynamics. The XKR-S utilizes a sophisticated automatic transmission system. For a total fill, the system requires 10.6 quarts of fluid. Using a synthetic automatic transmission fluid designed for fuel efficiency and high-load scenarios helps reduce internal friction, which can lead to better fuel economy and smoother gear shifts. These fluids are formulated to resist oxidation and thermal breakdown, which are common issues in stop-and-go traffic or during spirited acceleration where the transmission is under constant stress. Whether choosing the Signature Series for maximum performance or the OE line for excellent value, the goal is the same: to prevent wear on clutch packs and bands while ensuring clean, stable fluid properties.
Essential Maintenance for Brakes and Power Steering
Safety and control are paramount in a vehicle of this caliber. The braking system benefits greatly from a high-quality synthetic brake fluid. The 2012 XKR-S typically specifies a low viscosity DOT 4 fluid that meets the ISO 4925 Class 6 specification. AMSOIL’s DOT 3 and DOT 4 synthetic fluid offers a stable viscosity over a wide temperature range, ensuring consistent pedal feel and rapid response from the ABS system. This fluid helps prevent moisture accumulation, which can lower the boiling point and lead to brake fade under hard braking.
For the power steering system, the vehicle requires a fluid compatible with DEXRON-III specifications. Using the correct fluid prevents noise, wear on the steering rack, and ensures that the power steering pump operates smoothly. Synthetic automatic transmission fluids, whether the Signature Series Multi-Vehicle or OE Multi-Vehicle formulations, are highly recommended for this application. They offer excellent lubricity and protection against varnish buildup, which can compromise the hydraulic pressure needed for precise steering inputs at low speeds and high speeds alike.
Protecting the Fuel System and Exterior
To ensure the engine breathes freely and runs at peak efficiency, fuel system cleanliness is essential. Carbon deposits can form on fuel injectors and intake valves, leading to reduced power and poor fuel economy. AMSOIL’s fuel additives, such as the P.i.® Performance Improver Gasoline Additive, are designed to restore fuel injectors to 100% flow rate and improve horsepower. This additive helps control pre-ignition knock and is compatible with capless fuel systems, making it a versatile choice for keeping the combustion chamber clean.
For vehicle owners who store their XKR-S seasonally or wish to maintain its pristine appearance, AMSOIL offers a range of protection products. During storage periods, preventing fuel degradation and engine corrosion is critical. The Gasoline Stabilizer can keep fuel fresh for up to 12 months, preventing varnish buildup in the fuel system. For long-term engine protection, the Engine Fogging Oil creates a protective film over internal components to prevent rust. Exterior care is also important for a high-performance sports car. Products like the Exterior Ceramic Spray provide a durable, water-shedding layer that protects against UV rays and environmental contaminants, while the Miracle Wash allows for easy cleaning without the need for water, preserving the vehicle’s finish and preventing swirl marks.
