Maintaining the precise lubrication specifications required for the 2008 Land Rover Range Rover 4.4L is essential for preserving the engine’s longevity and performance. This luxury SUV relies on high-quality synthetic fluids to handle its complex engineering, particularly given the high-output 4.4-liter V8 engine design. Using the correct oil viscosity and capacity, along with compatible filters and transmission fluids, ensures that critical components are protected against wear, sludge, and extreme operating temperatures.
Recommended AMSOIL Products
- AMSOIL Signature Series 5W-30 100% Synthetic Motor Oil – The ultimate choice for maximum engine protection, offering superior wear resistance and horsepower retention. It is ideal for extending service intervals up to 25,000 miles or one year while providing excellent protection against turbocharger stress and high-temperature breakdown.
- AMSOIL Extended-Life 5W-30 100% Synthetic Motor Oil – A cost-effective alternative that delivers robust cleaning power and extended protection for up to 20,000 miles. This formulation helps keep the engine running smoothly by minimizing deposits and providing reliable performance under varying driving conditions.
- AMSOIL OE 5W-30 100% Synthetic Motor Oil – Designed specifically to fight sludge and deposits while meeting the stringent requirements of modern European engines. It offers a high-performance synthetic formula that ensures excellent cleaning capabilities and protection for daily drivers seeking reliability without the premium price tag of the Signature Series.
- AMSOIL 5W-30 100% Synthetic High-Mileage Motor Oil – A specialized blend formulated for vehicles with over 75,000 miles, featuring enhanced detergents to clean existing deposits and additives to reduce oil consumption. This oil helps revitalize older engines by restoring performance and reducing sludge buildup by up to 67%.
- WIX Oil Filter – A premium filtration component that outperforms original equipment manufacturer filters in many metrics. Using this filter ensures that contaminants are effectively removed from the oil, protecting the 4.4L engine from abrasive particles and ensuring optimal lubrication flow.
The 4.4-liter V8 engine in the 2008 Range Rover requires a substantial oil volume to ensure adequate circulation throughout the engine block and cylinder heads. When performing an oil change, the total capacity required is 8.5 quarts when including a filter replacement, with a standard refill capacity of 8.1 quarts. Properly filling the engine to the recommended level is critical, as under-filling can lead to inadequate lubrication and overheating, while over-filling may cause foaming and increased pressure within the crankcase. The torque specification for the oil drain plug should be set to 18 ft/lbs to ensure a secure seal without damaging the threads.
Transmission and Transfer Case Protection
Powering this vehicle is a 6-speed automatic transmission (6HP26) that demands a fluid capable of withstanding significant thermal loads and friction. AMSOIL recommends the Signature Series Fuel-Efficient 100% Synthetic Automatic Transmission Fluid or the OE Fuel-Efficient variant for optimal shifting performance and durability. The total fill capacity for this transmission is 10 quarts, which ensures that all clutch packs and bands are properly saturated and cooled. These fluids are engineered to withstand heavy towing, elevated temperatures, and challenging terrain, remaining fluid even in sub-zero conditions.
The front and rear differentials also require specific attention to prevent wear and thermal runaway. For both the front and rear open differentials, AMSOIL SEVERE GEAR 75W-90 100% Synthetic Gear Lube is the recommended lubricant. This synthetic gear lube contains friction modifiers suitable for limited-slip applications and helps reduce operating temperatures. The front differential capacity is 1.3 pints, while the rear open differential requires 2.4 pints. Using a high-quality synthetic gear lube extends the life of the gear teeth and seals, protecting the drivetrain from rust and corrosion.
Cooling System and Brake Fluid
Effective thermal management is crucial for the Range Rover’s performance, especially given its size and the heat generated by the V8 engine. The cooling system holds 11.8 quarts of fluid. For long-lasting protection, the AMSOIL Passenger Car & Light Truck Antifreeze & Coolant is an excellent choice, offering a unique poly-organic acid formulation that is compatible with all cooling system metals, gaskets, and hoses. This pre-mixed 50/50 formulation is phosphate-, nitrate-, nitrite-, silicate-, borate-, and amine-free, ensuring safety for the entire cooling system. Alternatively, the concentrated AMSOIL Propylene Glycol Antifreeze and Engine Coolant provides protection up to 150,000 miles or 5 years, allowing owners to mix their own solution for specific climate requirements.
Brake safety should never be compromised. The 2008 Range Rover utilizes hydraulic brake fluid that meets DOT 4 specifications. AMSOIL DOT 3 and DOT 4 100% Synthetic Brake Fluid provides excellent responsiveness for ABS and traction control systems. Its stable viscosity over a wide temperature range ensures consistent pedal feel and braking performance in both hot and cold weather, preventing the boil-over issues that can occur with conventional brake fluids under heavy use.
For seasonal storage or extended periods of inactivity, the vehicle benefits from fuel system protection. AMSOIL Gasoline Stabilizer helps keep fuel fresh for up to 12 months, protecting against varnish, gum buildup, and ethanol corrosion. Additionally, AMSOIL Engine Fogging Oil can be used to protect internal engine components from rust and corrosion while the vehicle is parked. For regular maintenance and fuel economy improvement, AMSOIL P.i. Performance Improver can be added to the fuel tank to restore horsepower and clean GDI fuel injectors, ensuring the engine runs efficiently and smoothly.
