Maintaining the 2012 Jaguar XF with the 5.0L DOHC B engine requires specific lubricants designed to meet the rigorous standards of British engineering. This luxury sedan is equipped with a high-output V8 engine and sophisticated transmission systems that demand precise viscosity and thermal stability to ensure optimal performance and longevity. Neglecting fluid quality can lead to premature wear, reduced fuel efficiency, and costly repairs. Using synthetic lubricants formulated for this specific application helps protect against the extreme thermal loads and high-speed operation characteristic of the Jaguar platform.

Engine Oil and Capacity Specifications
The heart of the 2012 Jaguar XF is the 5.0L naturally aspirated V8 engine. Proper lubrication is critical for this high-displacement engine to maintain oil pressure and thermal stability. For this specific configuration, the required motor oil viscosity is 5W-20. This viscosity grade is essential for ensuring proper oil flow during cold starts while maintaining adequate film strength at high operating temperatures. The total oil capacity, including the oil filter replacement, is 7.7 quarts. After refilling the system, it is imperative to check the oil level and ensure the oil drain plug is torqued to 17 ft/lbs to prevent leaks or thread damage. AMSOIL Signature Series 5W-20 synthetic motor oil is engineered to exceed original equipment manufacturer requirements, offering 75% more engine protection against horsepower loss and wear compared to industry standards. This oil helps keep the engine clean and extends service intervals significantly, reducing the frequency of maintenance stops while maximizing vehicle performance.
Transmission and Differential Lubrication
The powertrain of the 2012 Jaguar XF relies on a 6HP28 automatic transmission, which requires a specialized fluid to handle the demands of a luxury sedan. A total fill capacity of 10.6 quarts is required for the transmission to ensure complete lubrication and proper fluid levels in all torque converter passages. Using a high-quality synthetic transmission fluid like AMSOIL Signature Series Fuel-Efficient Automatic Transmission Fluid ensures the transmission remains fluid even in sub-zero temperatures and resists degradation under heavy use or towing. This protection is vital for preventing sludge buildup and maintaining shift quality.
For the rear differential, the vehicle utilizes a limited-slip configuration that benefits significantly from high-performance gear lube. The capacity for the rear differential is 1.9 pints. AMSOIL SEVERE GEAR 75W-90 synthetic gear lube is specifically formulated to control thermal runaway, a common issue in high-performance differentials, and protect against rust and corrosion. The inclusion of friction modifiers in this product helps reduce wear in limited-slip applications, ensuring the differential operates smoothly and quietly throughout the vehicle’s service life.
Cooling and Brake System Fluids
Maintaining the correct temperature and braking performance is as important as engine lubrication. The cooling system for the 2012 Jaguar XF has a capacity of 13.2 quarts, requiring a substantial amount of coolant to cover the entire system. AMSOIL offers two primary options: the Passenger Car & Light Truck Antifreeze & Coolant, which comes as a convenient 50/50 pre-mix, and the Propylene Glycol Antifreeze, a concentrated option that requires mixing with distilled water. Both formulations provide up to 150,000 miles of protection and are free from phosphates, nitrates, and borates, making them safe for all cooling system metals and hoses.
The braking system relies on high-quality fluid to maintain responsiveness. The manufacturer notes that Shell DOT 4 ESL is the preferred fluid, but a low viscosity DOT 4 fluid meeting ISO 4925 Class 6 specifications is an acceptable alternative. AMSOIL DOT 3 and DOT 4 100% Synthetic Brake Fluid meets these rigorous standards, offering stable viscosity across a wide temperature range. This stability ensures consistent pedal feel and responsive ABS and traction control performance, which are critical for the handling dynamics of the Jaguar XF.
Additional Maintenance and Fuel Care
Beyond the core lubrication points, several other fluids contribute to the overall health of the vehicle. For the power steering system, the vehicle requires a DEXRON-III Automatic Transmission Fluid. AMSOIL Signature Series Multi-Vehicle ATF or OE Multi-Vehicle ATF can be used to fulfill this requirement, providing the necessary lubrication and hydraulic properties for smooth steering assistance.
To enhance fuel economy and engine performance, the use of fuel additives is recommended. AMSOIL P.i.® Performance Improver Gasoline Additive can restore up to 14% horsepower and clean GDI fuel injectors, which is particularly beneficial for direct injection engines. Additionally, for vehicles that undergo seasonal storage, AMSOIL Gasoline Stabilizer can keep fuel fresh for up to 12 months, preventing varnish and gum buildup that can clog fuel lines and injectors.
