Proper maintenance is the lifeblood of your 2023 Land Rover Discovery. This luxury SUV is an engineering marvel designed to traverse challenging terrain while offering a refined on-road experience, but its complex systems, including the turbocharged 3.0L engine and advanced transmission, demand the highest standards of care. Using the correct synthetic lubricants ensures that every component, from the turbocharger to the transfer case, operates with optimal friction protection and thermal stability. This guide outlines the specific AMSOIL products and fluid capacities required to keep your Discovery running at peak performance for years to come.
Recommended AMSOIL Products

Engine Oil and Filter Specifications
The heart of your 2023 Land Rover Discovery is the 3.0L 6-cylinder engine with the [U] U Turbo code. To maintain the warranty and ensure longevity, you must use the correct viscosity grade specified by the manufacturer. The recommended oil grade for all temperature conditions is 0W-20. This low-viscosity synthetic oil is critical for providing immediate lubrication during cold starts while maintaining a protective film at high operating temperatures, a necessity for a turbocharged engine that generates significant heat.
The oil capacity for a complete change, including the filter, is 9.3 quarts. It is vital to pour the correct amount and verify the level after refilling to prevent over-filling or under-filling. When servicing the engine, always replace the oil drain plug with a new one, torquing it to the specified 22 ft/lbs. The engine oil filter is a key component in this maintenance routine; however, specific part recommendations for the filter itself are currently listed as unavailable in the immediate database, suggesting that a compatible OEM or high-quality aftermarket filter should be used to match the AMSOIL 0W-20 LS 100% Synthetic European Motor Oil.
AMSOIL 0W-20 LS 100% Synthetic European Motor Oil is engineered specifically for the unique demands of modern European vehicles. It features a precise blend of synthetic base oils and premium additives that exceed original equipment manufacturer requirements. This oil is designed to keep the turbocharger spinning freely and the internal engine components clean, resisting the sludge and varnish that can form during short trips or stop-and-go traffic.
Automatic Transmission and Transfer Case Fluids
The 2023 Discovery relies on an 8HP76 automatic transmission, which is a sophisticated 8-speed unit. Proper fluid is essential for the longevity of this transmission, especially if you plan to use the vehicle for towing or off-road excursions. The total fill capacity for the 8-speed transmission is 9 quarts. For this application, AMSOIL Signature Series Fuel-Efficient 100% Synthetic Automatic Transmission Fluid is the top-tier recommendation. It is formulated to withstand the intense heat and stress of heavy towing, elevated temperatures, and challenging terrain. It remains fluid in sub-zero conditions, ensuring fast, precise shifts even when the vehicle is cold. This fluid provides reserve protection during heavy use, preventing wear and extending the service interval.
Alternatively, the AMSOIL OE Fuel-Efficient 100% Synthetic Automatic Transmission Fluid offers a robust alternative that protects against wear and maintains fluidity. Both options are designed to outlast conventional fluids, reducing the likelihood of transmission slippage or harsh shifting that can occur when the fluid breaks down.
For the transfer case, the lubrication requirements vary slightly based on whether you have a single-speed or twin-speed configuration. The single-speed transfer case requires 1.7 pints of lubricant, while the twin-speed version requires 2.7 pints. The recommended fill method is to fill the transfer case to the bottom edge of the fill plug opening. The transfer case lubricant used should meet the GLSI8 specification. The Signature Series Automatic Transmission Fluid is also frequently recommended for these transfer cases due to its exceptional thermal stability and protective properties, ensuring the powertrain distribution system operates smoothly.
Cooling System and Brake Fluid Requirements
Maintaining the cooling system is just as important as the engine oil. The 2023 Discovery requires specific antifreeze formulations to protect the aluminum components and various metals within the cooling system. There are different capacity requirements depending on the specific configuration of your vehicle’s cooling package.
For vehicles equipped with the FFBH configuration, the AMSOIL Passenger Car & Light Truck Antifreeze & Coolant capacity is 18.9 quarts. If the vehicle has an “O” configuration, the capacity is 18 quarts. For the RAC configuration, the capacity rises to 20.8 quarts. This unique poly-organic acid (OAT) formulation is a 50/50 pre-mix, meaning it requires no additional water mixing and is ready to pour. It is compatible with all other antifreeze colors and is free of phosphates, nitrates, nitrites, silicates, borates, and amines, ensuring it is safe for all cooling system metals, gaskets, and hoses. It provides protection for up to 150,000 miles or 5 years.
The AMSOIL Propylene Glycol Antifreeze and Engine Coolant is a concentrated alternative for those who prefer to mix their own. It can protect up to 150,000 miles or 5 years in passenger cars and light trucks, and even longer in heavy-duty applications. This option is phosphate-, nitrate-, nitrite-, silicate-, borate-, and amine-free, offering superior corrosion protection.
Regarding the braking system, the 2023 Land Rover Discovery recommends the use of Land Rover specific brake fluid. However, if that specific fluid is unavailable for topping up, a low viscosity DOT 4 brake fluid meeting ISO 4925 Class 6 requirements can be used. The AMSOIL DOT 3 and DOT 4 100% Synthetic Brake Fluid is an ideal choice that provides excellent responsiveness for ABS and traction control systems. It maintains a stable viscosity over a wide temperature range, preventing the boiling points associated with conventional fluids from dropping during heavy braking events.
Additional Maintenance and Cleaning
To keep your Land Rover Discovery in pristine condition, AMSOIL offers a range of additives and cleaning products. For fuel system maintenance, the AMSOIL P.i.® Performance Improver can help restore up to 14% horsepower and clean GDI fuel injectors to 100% flow rate after one tank of fuel. It also improves fuel economy and helps prevent carbon buildup and pre-ignition knock. For storage, the AMSOIL Gasoline Stabilizer keeps fuel fresh for up to 12 months, protecting against varnish and ethanol corrosion.
During seasonal changes, the AMSOIL Engine Fogging Oil is excellent for protecting internal engine components during long periods of inactivity. For vehicle cleaning, the AMSOIL Miracle Wash offers a waterless wash and wax solution that repels dust and protects against UV rays, while the AMSOIL Engine Degreaser effectively removes stubborn grease and grime from engine surfaces.
