The 2012 Jaguar XK features a sophisticated 5.0-liter V8 engine code DOHC B, which is the heart of this luxury sports car. This powerplant is renowned for its smooth power delivery and robust torque, characteristics that are amplified by the use of high-quality synthetic lubricants. Proper fluid management is not just about meeting manufacturer minimums; it is about maximizing the potential of this powerful engine. By utilizing AMSOIL’s specialized fluids, you ensure that the engine operates with reduced friction, which translates to better fuel economy, reduced wear on critical components, and a longer service life for the vehicle.
Engine Oil Specifications
For the 2012 Jaguar XK with the 5.0L V8, the manufacturer specifies a 5W-20 viscosity grade for all operating temperatures. The total capacity, including the filter replacement, is 7.7 quarts. It is crucial to check the oil level after refilling and to torque the oil drain plug to the correct specification of 17 ft/lbs. AMSOIL Signature Series 5W-20 100% Synthetic Motor Oil is engineered to protect turbochargers 72% better than the required GM dexos1 Gen 2 specification, providing a significant performance advantage for owners who push their vehicles. This oil is trusted by professional engine builders and offers guaranteed protection for up to 25,000 miles or one year, which is a substantial interval extension compared to conventional synthetic oils.
Transmission and Differential Care
The automatic transmission in this model is a 6HP28 unit, which requires a fluid change to maintain shifting quality and protect internal components. A total fill capacity of 10.6 quarts is required for the 6-speed system. AMSOIL Signature Series Fuel-Efficient 100% Synthetic Automatic Transmission Fluid is designed 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 the rear differential, which uses a GLS24 specification, the capacity is 1.9 pints. AMSOIL SEVERE GEAR 75W-90 provides advanced protection against wear and rust, controlling thermal runaway to help reduce operating temperatures and extend the life of seals and equipment.
Cooling System and Brake Fluid
Keeping the cooling system in peak condition is vital for the longevity of the V8 engine. The 2012 Jaguar XK has a cooling system capacity of 10 quarts. AMSOIL Passenger Car & Light Truck Antifreeze & Coolant is an ethylene glycol 50/50 pre-mix formulation that offers protection up to 150,000 miles or 5 years. It is compatible with all other antifreeze and coolant colors and contains no phosphates, nitrates, nitrites, silicates, borates, or amines, ensuring compatibility with all cooling system metals and hoses. For the braking system, while Shell DOT 4 ESL is the preferred fluid, AMSOIL DOT 3 and DOT 4 100% Synthetic Brake Fluid is an excellent alternative that meets ISO 4925 Class 6 specification, ensuring responsive braking and ABS functionality.
