The 2022 Lexus RC300 is powered by the robust 3.5-liter V-6 engine, known by the code 2GR-FKS. This powerplant is engineered for a blend of spirited performance and refined reliability, but it requires specific lubrication to maintain its precision. The engine calls for a viscosity of 0W-20, and the oil pan holds a capacity of 6.8 quarts, including the filter. Using the correct fluid ensures that the engine’s VVT-i system and high-compression piston rings operate smoothly under both cold starts and high-load conditions.

Ensuring the proper viscosity and type of oil is critical for the 2GR-FKS engine found in the RC300. This engine utilizes Toyota’s Dynamic Force technology and features dual VVT-i systems. These systems rely on oil pressure to adjust valve timing precisely. Using a lower-quality conventional oil can lead to sluggish valve response, increased friction, and accelerated wear on the camshafts and timing chain components. AMSOIL synthetic motor oils are formulated to maintain their viscosity at extreme temperatures, ensuring the VVT-i actuators receive the consistent hydraulic pressure they need for optimal performance. This protection is vital for maintaining fuel efficiency and power delivery over the life of the vehicle.
Complete Lubrication Schedule
While motor oil is the most critical component, a complete maintenance strategy involves every fluid in the drivetrain and cooling system. The engine requires a full capacity of 6.8 quarts when performing a standard oil change with a filter replacement. After refilling, it is essential to check the oil level to ensure accuracy. For transmission maintenance, the automatic transmission (A760H) has a total fill capacity of 10.6 quarts for a complete change, though initial fill amounts are lower. The differential and transfer case also require specific lubricants to handle the torque and wear associated with the vehicle’s all-wheel-drive capabilities.
The cooling system of the RC300 holds approximately 10 quarts of coolant. AMSOIL Passenger Car & Light Truck Antifreeze & Coolant is a phosphate-, nitrate-, nitrite-, silicate-, borate-, and amine-free formulation that protects all cooling system metals, gaskets, and hoses. This OAT-based coolant is compatible with the Toyota cooling system materials and offers protection up to 150,000 miles. For those in colder climates or seeking a concentrated option, the Propylene Glycol Antifreeze and Engine Coolant provides even more flexibility, allowing for mixing ratios to be adjusted for specific temperature ranges without sacrificing corrosion inhibition.
Transmission and differential maintenance is often overlooked, yet it is crucial for the longevity of the drivetrain. The A760H automatic transmission benefits from the extreme pressure additives found in the Signature Series Fuel-Efficient Automatic Transmission Fluid. This fluid resists thermal breakdown, which is common in stop-and-go traffic or when towing. Similarly, the limited-slip differential requires a gear lube with friction modifiers to prevent chatter and ensure smooth power delivery. AMSOIL SEVERE GEAR® 75W-85 and 75W-90 synthetic gear lubes are designed to meet these demands, offering superior wear protection and thermal stability compared to conventional mineral oils.
For vehicle owners who engage in seasonal storage or drive in dusty environments, additional protection can be beneficial. AMSOIL Gasoline Stabilizer keeps fuel fresh for up to 12 months, preventing varnish and gum buildup in the fuel injectors. During storage, Engine Fogging Oil coats internal engine components to prevent rust and corrosion. For regular cleaning and maintenance, the P.i. Performance Improver gasoline additive can restore up to 14% horsepower and clean GDI fuel injectors, ensuring the engine runs as efficiently as the day it left the factory.
About the 2022 Lexus RC300
The 2022 Lexus RC300 represents the brand’s commitment to the grand tourer segment, blending aggressive styling with luxurious appointments. Part of the second-generation RC lineup, which debuted in 2015, this vehicle is built on the luxury sport coupe platform that emphasizes a low center of gravity and a driver-focused cockpit. The RC300 specifically is powered by a naturally aspirated 3.5-liter V-6 engine, the 2GR-FKS, which produces a healthy amount of horsepower and torque while maintaining a linear and responsive power delivery. This engine is distinct from the RC 300’s twin-turbo sibling found in the RC300 (in markets like North America, the RC300 often refers to the 2.0L turbo in some contexts, but the source summary specifies the 3.5L 2GR-FKS, which is the hallmark V-6 powerplant). The 3.5-liter V-6 is renowned for its smoothness, high-revving nature, and ability to sustain performance over long periods of hard driving.
Lexus designed the RC300 to appeal to enthusiasts who value precision handling and refined comfort. The vehicle features a sophisticated chassis with MacPherson struts in the front and a double-wishbone setup in the rear, allowing for excellent body control and feedback. Interior appointments typically include supportive seats, high-quality leather, and a user-friendly infotainment system, though the focus remains squarely on the driving experience. The RC300 is a favorite among owners who appreciate the balance between a daily usable car and a weekend toy, offering the space for occasional passengers without sacrificing the dynamic driving character of a sports coupe.
Despite its robust engineering, the 2022 Lexus RC300 is not immune to common issues that affect high-performance vehicles. Owners have occasionally reported carbon buildup on the intake valves of direct-injection engines, which can lead to rough idling and reduced fuel economy over time. The use of AMSOIL’s P.i. Performance Improver can help mitigate this by cleaning injectors and preventing carbon deposits. Another concern for V-6 engines is oil sludge, particularly if the vehicle is subjected to frequent short trips that prevent the engine from reaching optimal operating temperatures. AMSOIL synthetic oils, with their superior detergents and high-temperature stability, are excellent at preventing sludge formation, keeping the engine internals clean. Additionally, some owners note potential heat soak in the engine bay during spirited driving, which can affect oil temperatures. Using a high-quality synthetic oil like the Signature Series helps maintain a protective film even under thermal stress. Finally, the limited-slip differential can sometimes exhibit chatter if the fluid breaks down or if the wrong lubricant is used. Regular maintenance with AMSOIL SEVERE GEAR® synthetic gear lube ensures the differential operates smoothly, eliminating noise and improving traction.
Ultimately, the 2022 Lexus RC300 with the 3.5L V-6 is a capable and rewarding vehicle. By choosing premium synthetic lubricants, owners can maximize the engine’s potential, extend the life of the transmission and differential, and ensure the car performs at its peak regardless of the driving conditions. Whether navigating city streets or tackling winding roads, the right fluids provide the foundation for a reliable and enjoyable ownership experience.
