The heart of the 2022 Genesis G90 is its 3.3L twin-turbocharged V6 engine. This powertrain generates substantial power, placing significant thermal and mechanical stress on internal components. Because of the turbochargers, which spin at incredibly high speeds, the engine oil must provide exceptional cooling and film strength. The AMSOIL Signature Series 5W-30 is particularly beneficial here, offering protection against horsepower loss and wear that outperforms many industry standards. For those seeking maximum protection in extreme conditions, the Extended-Life and OE formulations also provide robust defense against low-speed pre-ignition, a known concern in direct-injection turbo engines. The required fill capacity is 7.3 quarts, including the filter replacement, and the drain plug torque should be maintained between 25-33 ft/lbs.
Beyond the engine, the cooling system plays a critical role in the longevity of the G90. With a total capacity of 10.4 quarts, the cooling system requires a fluid that prevents corrosion and boiling over under load. The AMSOIL Passenger Car & Light Truck Antifreeze & Coolant is a convenient 50/50 pre-mix that protects the engine block, head, and radiator for up to 150,000 miles or five years. Alternatively, the concentrated Propylene Glycol Antifreeze offers extreme durability for heavy-duty applications or those seeking a custom mixing ratio for specific environmental needs.
Transmission and Differential Lubrication
The 2022 Genesis G90 utilizes an advanced eight-speed automatic transmission (A8TR1-1). This gearbox is designed for smooth shifts and fuel efficiency, but it requires fluid capable of withstanding the rigors of heavy towing and high-speed driving. The total fill capacity for the automatic transmission is 9.7 quarts. AMSOIL Signature Series Fuel-Efficient Automatic Transmission Fluid helps the transmission remain fluid in sub-zero temperatures while providing reserve protection during heavy use. For drivers looking for a reliable OE-specific option, the AMSOIL OE Fuel-Efficient Transmission Fluid offers similar protection against wear and temperature-related issues.
The differential systems also require attention to ensure smooth power delivery to the wheels. Both the front and rear differentials utilize GL-5 gear oils. The front differential requires 1.5 pints of fluid, while the rear differential requires 3 pints. AMSOIL SEVERE GEAR 75W-85 100% Synthetic Gear Lube is recommended for these units. This fluid helps control thermal runaway, reduces operating temperatures, and extends the life of the seals and gears. It is specifically formulated to handle the high loads found in luxury sedans and SUVs.
Other Essential Fluids and Additives
Maintaining the G90’s braking system is equally vital for safety. The vehicle recommends DOT 3 and DOT 4 compliant AMSOIL DOT 3 and DOT 4 100% Synthetic Brake Fluid. This fluid ensures excellent responsiveness for the ABS and traction control systems, maintaining a stable viscosity whether braking in freezing cold or scorching heat. For those interested in optimizing fuel economy or restoring engine performance, AMSOIL P.i. Performance Improver can help restore fuel injectors to 100% flow rate and reduce carbon buildup in the combustion chamber.
Vehicle Background and Performance Profile
The 2022 Genesis G90 represents the pinnacle of the Genesis brand’s luxury sedan lineup, offering a commanding presence on the road. Born from Hyundai’s separate luxury division, Genesis has carved out a unique niche by combining German-like build quality with distinct Korean design language and value-driven features. The G90 serves as the flagship, competing directly with established players like the Mercedes-Benz S-Class, BMW 7 Series, and the Audi A8.
Under the hood, the 3.3L twin-turbo V6 engine is a marvel of modern engineering, delivering smooth power and responsive acceleration. This engine code is often associated with the [A] 0 Turbo designation, highlighting its advanced turbocharging technology. The vehicle’s chassis is designed to offer a balance of sporty handling and supreme ride comfort, utilizing adaptive dampers and a sophisticated suspension setup to absorb road imperfections. This makes the G90 an excellent choice for long-distance travel, where driver and passenger comfort are paramount.
Owners of the 2022 G90 typically appreciate its spacious interior, which rivals some larger vehicles in the segment. The cabin is filled with premium materials, advanced technology, and cutting-edge safety features. The driving character is refined yet energetic, thanks to the twin-turbo engine that provides ample torque at lower RPMs. This powertrain ensures that merging onto highways or overtaking slower traffic is effortless, while still delivering a smooth and quiet ride at cruising speeds.
Despite its robust engineering, like any complex vehicle, the G90 can face specific challenges as it accumulates mileage. One common issue in twin-turbo V6 engines is carbon buildup on intake valves, which can lead to rough idling and reduced fuel efficiency. Using high-quality synthetic motor oils and fuel system cleaners like AMSOIL P.i. can help mitigate this accumulation. Additionally, turbocharger bearings are sensitive to oil quality; using a robust synthetic oil like Signature Series helps ensure proper lubrication and cooling, extending the life of these critical components. Another potential concern involves the automatic transmission’s sensitivity to fluid breakdown under extreme heat. Regular fluid changes with high-performance transmission fluid can prevent shifting delays or harshness. Finally, cooling system issues, such as gasket failure or antifreeze degradation, can arise over time; a high-quality antifreeze with superior corrosion inhibitors helps protect the expensive aluminum components within the engine and radiator. By addressing these potential areas proactively with the right lubricants, G90 owners can ensure their vehicle remains in peak condition for years to come.
