The heart of the 2022 Lexus LS500 is its V35A-FTS 0 twin-turbo V6 engine. This powerplant generates significant power and heat, necessitating a motor oil that can handle extreme thermal stress without breaking down. The standard recommendation is a 0W-20 viscosity. The engine holds approximately 7.5 quarts of oil when a filter change is included, though a refill check is required immediately after the service. The drain plug torque specification is 30 ft-lbs, and it is best practice to replace both the drain plug and its gasket during every oil change to ensure a perfect seal.
For owners of this high-performance luxury sedan, the AMSOIL Signature Series 0W-20 is often the top choice. This fluid is engineered to withstand the rigors of a turbocharged engine, providing 75% more engine protection against horsepower loss and wear compared to industry standards. It allows for extended service intervals of up to 25,000 miles or one year, making it ideal for those who want to maximize the time between visits to the service center. For drivers who prefer a slightly more economical option without sacrificing synthetic benefits, the AMSOIL Extended-Life 0W-20 offers a solid 20,000-mile guarantee and superior cleaning power to prevent sludge buildup.
Filtration is just as important as the oil itself. The AMSOIL Oil Filter (EA15K09) is designed to work in harmony with the synthetic oil, offering a filtering efficiency of 99% at 20 microns. This helps trap microscopic contaminants that can cause wear on the turbocharger bearings and engine internals. An alternative, the AMSOIL Oil Filter (EA15K49), provides a similar level of protection with potentially greater capacity for small, wear-causing particles. If you prefer a well-known aftermarket brand, the WIX Oil Filter (57173) is also a compatible and high-quality option that exceeds OEM specifications.
Moving to the drivetrain, the 2022 LS500 features a sophisticated 10-speed automatic transmission (AGA0F or AGA0E variants). Maintaining this transmission is crucial for preserving the smooth, silent shift quality that defines the vehicle. The total fill capacity is approximately 9.5 quarts, with an initial fill of about 0.7 quarts required during assembly. The AMSOIL Signature Series Fuel-Efficient 100% Synthetic Automatic Transmission Fluid is specifically formulated to handle the high heat and stress of modern automatic transmissions. It remains fluid in sub-zero temperatures and provides a reserve of protection during heavy use, ensuring the transmission shifts crisply even under load. The AMSOIL OE Fuel-Efficient 100% Synthetic Automatic Transmission Fluid is an excellent alternative that meets the specific wear protection requirements of the vehicle while supporting fuel efficiency.
The cooling system for the LS500, particularly with the twin-turbo setup, operates under significant thermal load. The intercooler requires 4.5 quarts, and the total coolant capacity varies by drivetrain, ranging from 11.1 quarts for AWD models to 11.2 quarts for RWD models. The AMSOIL Passenger Car & Light Truck Antifreeze & Coolant is a 50/50 pre-mix that is safe for all cooling system metals, gaskets, and hoses. It is phosphate-, nitrate-, and silicate-free, which is beneficial for the longevity of the aluminum and composite components in modern engines. Alternatively, the AMSOIL Propylene Glycol Antifreeze and Engine Coolant offers a concentrated solution for those who prefer to mix their own, providing superior corrosion resistance and a longer service life.
Finally, the rear differential requires a GL-5 specification fluid, such as 75W-85, to protect the gears and bearings. The capacity varies by drivetrain configuration: RWD models require 1.8 pints in the rear, while AWD models require 2.9 pints. The AMSOIL SEVERE GEAR 75W-85 is an ideal choice, containing friction modifiers for limited-slip applications and controlling thermal runaway to prevent premature gear wear. For braking safety, the AMSOIL DOT 3 and DOT 4 100% Synthetic Brake Fluid is recommended. It resists boiling under the intense heat generated by the heavy vehicle and ensures consistent pedal feel, a critical factor for a car of this caliber.
About the Vehicle
The 2022 Lexus LS500 represents the pinnacle of Lexus’s engineering, serving as the flagship luxury sedan in the brand’s global lineup. Built on the GA-L (Global Architecture-Luxury) platform, the LS500 combines a lightweight, high-strength body structure with a low center of gravity to deliver a driving dynamic that is both smooth and agile. Under the hood lies the 3.4-liter V35A-FTS twin-turbocharged V6 engine, which pairs seamlessly with an innovative 10-speed automatic transmission. This powertrain delivers a commanding presence with a harmonious blend of power and refinement, allowing the LS500 to compete at the highest level of the luxury sedan market.
Owners of the LS500 appreciate its “refined quietness” and the exceptional isolation from road noise, a hallmark of the LS series. The interior is a sanctuary of comfort, featuring opulent materials, advanced seating technology, and cutting-edge infotainment systems. Whether navigating city streets or cruising on the highway, the LS500 is designed to offer a ride that feels effortlessly composed. The vehicle is available in rear-wheel-drive and all-wheel-drive configurations, with the latter providing enhanced traction in adverse weather conditions without sacrificing the driving dynamics that make the LS500 a joy to drive.
Despite its robust build quality, like any high-performance vehicle, the LS500 can encounter specific issues over time. One common concern among owners is the potential for carbon buildup on the intake valves of the direct-injection twin-turbo V6 engine. Using high-quality synthetic oils and fuel additives can help mitigate this, as can occasional short trips that keep the engine temperature optimal. Another area of attention is the cooling system, where the high thermal output of the twin turbos demands a coolant with superior heat transfer capabilities to prevent overheating or corrosion in the aluminum intercooler components. Additionally, some owners report issues with the 10-speed transmission shifting abruptly or harshly under light throttle; regular fluid changes with a fluid specifically designed for high-temperature stability can help smooth out these shifts and extend the life of the transmission clutches. Finally, the rear suspension bushings on the LS500 can sometimes develop noise or play over time due to the weight of the vehicle and the forces of the twin-turbo engine; while lubrication does not fix the bushings themselves, using a synthetic grease on suspension components during maintenance can help prevent premature wear and ensure smooth operation. By addressing these potential points of failure with the right AMSOIL fluids, LS500 owners can maintain the vehicle’s luxury status and performance for the long haul.
Regular maintenance with the recommended AMSOIL products ensures that the 2022 Lexus LS500 continues to perform at its peak. Whether you are extending service intervals or simply wanting the best protection for your investment, these synthetic fluids provide the peace of mind that comes with knowing your luxury sedan is being cared for with the highest standards. From the engine block to the differential, every component of the LS500 benefits from the advanced chemistry found in these lubricants, ensuring a smoother, more reliable ownership experience.
