Engine Oil and Filtration Specifications
The heart of the 2021 Range Rover Sport, the 5.0L supercharged V8, requires a lubricant that can withstand high thermal loads while maintaining film strength at startup. For this engine, the correct viscosity is 0W-20 for all temperature conditions. The oil capacity for a standard service, including the filter replacement, is 8.5 quarts. It is critical to check the oil level after the refill to ensure accuracy. The oil drain plug should be torqued to 18 ft/lbs, and the old plug should always be discarded and replaced with a new one during every service.
While the vehicle summary does not list a specific AMSOIL oil filter for this engine code, the use of AMSOIL synthetic motor oil is the primary recommendation. The oil itself is formulated with precise blends of synthetic base oils and premium additives designed to handle the unique requirements of European powertrains. By switching to a full synthetic motor oil like the AMSOIL 0W-20 LS, owners can improve engine cleanliness and reduce wear on critical components such as camshafts, lifters, and valve train parts.
Transmission and Drivetrain Fluids
The 2021 Range Rover Sport is equipped with an 8HP70 8-speed automatic transmission. This complex gearbox benefits significantly from a synthetic fluid that can maintain its viscosity under extreme loads. The total fill capacity for the transmission is 9 quarts. For owners looking for maximum durability and performance, the AMSOIL Signature Series Fuel-Efficient 100% Synthetic Automatic Transmission Fluid is an excellent choice. It remains fluid in sub-zero temperatures while providing reserve protection during heavy use and towing.
Alternatively, the AMSOIL OE Fuel-Efficient 100% Synthetic Automatic Transmission Fluid offers protection against wear while meeting original equipment specifications. Both options ensure the transmission shifts smoothly and protects against the heat generated by the powerful engine. The drivetrain also includes front and rear differentials requiring specific gear lubricants. The front differential has a capacity of 1.1 pints, while the rear open unit requires 1.7 pints. The AMSOIL SEVERE GEAR® 75W-90 is recommended for these differentials, as it helps reduce operating temperatures and contains friction modifiers suitable for limited-slip applications.
Cooling System and Brake Fluid
Proper cooling system management is vital for the longevity of the 5.0L engine. The AMSOIL Passenger Car & Light Truck Antifreeze & Coolant capacity varies depending on the specific air conditioning configuration of the vehicle. Models with two-zone AC require 9.5 quarts, while those with four-zone AC require 11.1 quarts. Specific configurations with Front Frame Brake Heat (FFBH) may require slightly different volumes, up to 11.2 quarts. The AMSOIL Propylene Glycol Antifreeze and Engine Coolant is a phosphate-, nitrate-, nitrite-, silicate-, borate-, and amine-free solution that protects all cooling system metals and is compatible with all other antifreeze colors.
For braking systems, the 2021 Range Rover Sport requires brake fluid meeting Land Rover specifications. If the specific Land Rover fluid is unavailable for topping up, a low viscosity, DOT 4 brake fluid meeting ISO 4925 Class 6 requirements is acceptable. The AMSOIL DOT 3 and DOT 4 100% Synthetic Brake Fluid is ideal for maintaining brake pedal feel and responsiveness. It offers a stable viscosity range, preventing the spongy feel that can occur with conventional mineral-based fluids, especially during repeated hard braking.
Seasonal and Fuel Maintenance
Maintaining fuel quality is another key aspect of caring for this high-performance vehicle. For seasonal storage, the AMSOIL Gasoline Stabilizer helps keep fuel fresh for up to 12 months, protecting against varnish and gum buildup caused by ethanol corrosion. Additionally, the AMSOIL P.i.® Performance Improver Gasoline Additive can restore up to 14% of lost horsepower and clean GDI fuel injectors back to 100% flow rate after just one tank, improving fuel economy and reducing the need for higher-octane fuel.
About the Vehicle
The 2021 Land Rover Range Rover Sport is a flagship luxury sport utility vehicle that continues the legacy of combining off-road capability with on-road sophistication. Produced at the Solihull plant in the United Kingdom, this model is built on the D7x aluminum-intensive architecture, which contributes to a lighter curb weight compared to previous generations, thereby enhancing agility and fuel efficiency without sacrificing strength.
Powered by the 5.0L supercharged V8 engine, this vehicle delivers substantial power and torque, allowing for rapid acceleration that rivals many sports cars. The supercharger is driven by a belt connected to the crankshaft, ensuring immediate power delivery without the lag associated with traditional turbochargers. This engine choice is favored by enthusiasts who appreciate the linear power curve and the distinct sound of a naturally aspirated feel with forced induction. The Range Rover Sport is designed to handle a wide variety of terrains thanks to its Terrain Response® system, which intelligently manages throttle response, transmission shift points, and traction control to suit conditions ranging from mud and snow to rock and sand.
Despite its rugged reputation, the vehicle is marketed as a premium lifestyle SUV, often competing with high-end European rivals. It offers a luxurious interior with high-quality materials, advanced technology, and comfortable seating for five passengers. The 2021 model year features updated infotainment systems and driver assistance technologies that make it a comfortable cruiser for long-distance travel.
Owners of the 2021 Range Rover Sport should be aware of specific maintenance needs common to this platform. The air suspension system is a complex feature that provides a smooth ride but can be prone to air spring leaks over time, which can be exacerbated by road debris or harsh driving conditions. Using synthetic lubricants can help maintain the seals and dampers within the suspension system. Additionally, the vehicle is equipped with an electronic parking brake and various sensors that require precise operation; fluid compatibility is key to preventing corrosion in these sensitive systems. The engine itself, particularly the timing chain tensioners and the supercharger system, benefits from the high thermal stability of synthetic oils to prevent sludge buildup and wear under heavy loads. Finally, the electrical system, while advanced, can sometimes suffer from battery drain issues if the vehicle is not driven frequently, making fuel stabilizers and proper winterization practices essential for seasonal users.
By adhering to the recommended fluid specifications and utilizing high-performance synthetic lubricants, owners can mitigate these common issues and keep their Range Rover Sport performing at its best for years to come.
