Engine Oil Specifications and Maintenance
The heart of your 2018 Range Rover Sport is the 5.0L naturally aspirated V8 engine. This powerplant delivers significant power and torque, but it also generates substantial heat. AMSOIL recommends the 0W-20 viscosity grade for all temperature ranges. The oil capacity for a complete change, including the filter, is 8.5 quarts. After refilling, it is critical to check the oil level to ensure the proper volume is in the system. The oil drain plug should be torqued to 18 ft/lbs to prevent leaks or stripped threads.
Regular oil changes are essential for this vehicle. The synthetic nature of the recommended oils allows for extended drain intervals, providing protection far longer than conventional oils. The AMSOIL 0W-20 LS 100% Synthetic European Motor Oil is specifically engineered for the unique demands of European gasoline and hybrid vehicles. It contains a precise blend of synthetic base oils and premium additives that keep the engine clean and reduce friction.
While the source documentation does not list a specific AMSOIL oil filter code for this vehicle, regular filter changes remain a standard part of the maintenance schedule. Using high-quality lubricants in conjunction with the proper maintenance intervals ensures that the engine’s internal components, such as the timing chain and camshafts, remain protected from wear and deposits.
Transmission and Drivetrain Fluids
The 2018 Range Rover Sport is equipped with an 8HP70 8-speed automatic transmission. This sophisticated gearbox benefits greatly from a high-quality synthetic fluid that can handle the extreme heat generated during towing or spirited driving. The total fill capacity for the transmission is 9 quarts.
For the best performance, the AMSOIL Signature Series Fuel-Efficient 100% Synthetic Automatic Transmission Fluid is highly recommended. This fluid is designed to withstand the rigors of heavy towing, elevated temperatures, and challenging terrain while remaining fluid in sub-zero conditions. It provides a reserve of protection during heavy use, reducing the risk of sludge buildup and wear.
For owners seeking a high-performance alternative that meets original equipment specifications, the AMSOIL OE Fuel-Efficient 100% Synthetic Automatic Transmission Fluid offers excellent protection against wear and is an excellent choice for maintaining shift quality and transmission longevity.
The drivetrain also includes front and rear differentials that require proper lubrication. The front differential holds 1.1 pints, while the rear differential (Open type) holds 1.7 pints. Both units require a robust gear lube to handle the torque and potential off-road abuse. The AMSOIL SEVERE GEAR® 75W-90 100% Synthetic Gear Lube is ideal for these applications. It contains friction modifiers for limited-slip applications and helps reduce operating temperatures, extending the life of seals and equipment.
Cooling, Braking, and Fuel Systems
Proper cooling system maintenance is vital for the reliability of the 5.0L engine. The coolant capacity with a 2-Zone AC is 9.3 quarts. Owners can choose between two excellent coolant options. The AMSOIL Passenger Car & Light Truck Antifreeze & Coolant is a 50/50 pre-mix formulation that requires no mixing and offers protection up to 150,000 miles or 5 years. Alternatively, for those who prefer a concentrated option, the AMSOIL Propylene Glycol Antifreeze and Engine Coolant provides extended protection up to 150,000 miles or 5 years and can be diluted with distilled water for a custom mix.
Brake fluid maintenance is critical for safety. The vehicle requires a fluid meeting Land Rover specifications, typically DOT 4. The AMSOIL DOT 3 and DOT 4 100% Synthetic Brake Fluid provides excellent ABS and traction-control responsiveness. It maintains a stable viscosity over a wide temperature range, preventing the spongy pedal feel that can occur with degraded conventional fluids.
For fuel system health, especially in vehicles that may see stop-and-go city driving or high mileage, the use of a fuel additive is recommended. The AMSOIL P.i.® Performance Improver Gasoline Additive helps restore fuel injectors to 100% flow rate, improves fuel economy, and reduces the need for higher-octane fuel. It is compatible with capless fuel systems and helps prevent pre-ignition knock.
Model History and Performance
The 2018 Land Rover Range Rover Sport represents a blend of luxury, off-road capability, and high-performance engineering. Born from the brand’s reputation for creating capable off-roaders, the Sport variant is often viewed as the more dynamic and agile sibling to the full-size Range Rover. While both share the same prestigious lineage, the Sport model typically sits on a platform that allows for a more engaging driving experience, making it a favorite among drivers who value handling without sacrificing utility.
The 5.0L V8 engine is a hallmark of this era, offering smooth power delivery and the characteristic growl that enthusiasts have come to expect from British luxury SUVs. This naturally aspirated supercharged unit delivers substantial horsepower, propelling the heavy SUV with surprising vigor. The vehicle’s market position is clear: it is designed for owners who need a daily driver that can also handle demanding terrain, towing, or long highway commutes with ease.
Owners of the Range Rover Sport often appreciate the blend of on-road refinement and off-road prowess. However, like any high-performance vehicle with complex electronics and heavy mechanical components, it can face specific challenges as it ages. Using premium synthetic lubricants can help mitigate common issues associated with this platform. One such area is the cooling system; while generally robust, high-mileage engines can be prone to coolant degradation or overheating if the fluid loses its protective properties. Maintaining a superior coolant like AMSOIL can help prevent corrosion and ensure the engine stays within safe operating temperatures.
Another area where synthetic fluids provide a distinct advantage is in the transmission. The complex 8-speed automatic gearboxes are sensitive to fluid breakdown. Slipping or harsh shifting can sometimes be the first sign of transmission fluid degradation. High-quality synthetic transmission fluid helps maintain proper friction characteristics and fluidity, reducing the risk of these performance hiccups.
Additionally, the precision oil pump and variable valve timing systems in the 5.0L engine rely on clean, low-viscosity oil to function correctly. Synthetic oil resists breakdown better than conventional oil, ensuring that these sensitive components are always lubricated effectively. Finally, the vehicle’s braking systems, which are integral to its safety and performance, benefit from the stability of synthetic brake fluid, ensuring consistent pedal feel and ABS operation even under the most demanding braking scenarios.
