Maintaining the proper lubrication for your 2009 Lexus LX570 with the 5.7L V8 engine is essential for preserving its performance and extending its operational life. This luxury SUV relies on specific fluid formulations to handle the demands of heavy-duty use, towing, and extreme temperatures. Using high-quality synthetic lubricants ensures that the engine, transmission, and drivetrain components remain protected against wear, sludge, and thermal breakdown. Whether you are driving on highways, navigating off-road trails, or commuting through city traffic, the right fluids provide a critical layer of protection that standard maintenance might miss.

The 2009 Lexus LX570 is powered by the robust 5.7-liter 3UR-FE V8 engine, a powerhouse designed for both luxury and utility. This engine requires a precise viscosity grade to ensure optimal performance. For this specific model, the factory-recommended oil viscosity is 0W-20. The engine holds a capacity of 7.4 quarts when a filter replacement is included. It is crucial to check the oil level after refilling to ensure the proper amount is in the system. The drain plug torque specification is 30 ft/lbs, ensuring a secure seal during service.
Transmission and Drivetrain Protection
The automatic transmission in the LX570 is a complex system that benefits significantly from high-performance synthetic fluids. For the 6-speed AB60F transmission, the total fill capacity is 11 quarts, with an initial fill requirement of 2.2 quarts. Using a fluid designed to handle heavy towing and elevated temperatures is vital for preventing shudder and ensuring smooth shifts. AMSOIL offers both Signature Series and OE Fuel-Efficient options tailored for these transmissions.
The drivetrain also relies on specialized lubricants. The transfer case requires 3.2 pints of GL-5 rated AMSOIL SEVERE GEAR® 75W-90 gear lube, with a drain plug torque of 27 ft/lbs. The front differential holds 4 pints, while the rear differential requires 8.9 pints. Both differentials are specified for 75W-85 synthetic AMSOIL SEVERE GEAR® 75W-85 gear lube. These components endure high stress and heat, making the use of AMSOIL SEVERE GEAR® synthetic lubricants essential for preventing rust, corrosion, and thermal runaway. The friction modifiers in these lubes are particularly important for limited-slip differentials common in this class of SUV.
Cooling System and Brake Fluid
Proper cooling is non-negotiable for a vehicle of this size and power. The cooling system capacity is substantial at 17.6 quarts. Owners can choose between a ready-to-use pre-mix formulation or a concentrated ethylene glycol or propylene glycol AMSOIL Passenger Car & Light Truck Antifreeze & Coolant that requires mixing. Both options are formulated to be phosphate-, nitrate-, nitrite-, silicate-, and borate-free, ensuring compatibility with all cooling system metals and hoses while providing protection for up to 150,000 miles or five years.
Safety is paramount, and the brake fluid should never be overlooked. The LX570 utilizes a hydraulic brake fluid system. AMSOIL DOT 3 and DOT 4 100% Synthetic Brake Fluid is recommended. This fluid provides excellent responsiveness for ABS and traction control systems while maintaining a stable viscosity even as temperatures fluctuate. Unlike traditional fluids, synthetic options resist boiling and absorb less moisture, which helps maintain braking performance over time.
Additional Maintenance and Fluids
Power steering fluid for the 2009 LX570 is specified as DEXRON-III, and an automatic transmission fluid like the AMSOIL Signature Series Multi-Vehicle 100% Synthetic Automatic Transmission Fluid or AMSOIL OE Multi-Vehicle 100% Synthetic Automatic Transmission Fluid can be used effectively here. For owners looking to maintain peak fuel economy and engine cleanliness, AMSOIL P.i.® Performance Improver is a valuable additive that restores GDI fuel injectors and can recover up to 14% of lost horsepower. During seasonal storage, using AMSOIL Gasoline Stabilizer helps keep fuel fresh for up to 12 months, preventing varnish and gum buildup. Additionally, AMSOIL Engine Fogging Oil offers excellent protection against rust for internal engine components during long periods of inactivity.
Choosing the right lubricants is an investment in the longevity of your Lexus LX570. By adhering to the recommended capacities and utilizing synthetic products designed for high-performance applications, you ensure that your vehicle remains reliable in any condition.
