Ensuring your 2016 Infiniti Q50 receives the correct lubricants is the single most effective way to preserve the longevity and performance of its 3.0-liter twin-turbo V6 engine. The VR30DDTT powerplant operates under significant thermal and mechanical stress, particularly due to its forced induction system. Standard mineral oils can break down quickly under the intense heat generated by the turbochargers, leading to sludge formation, increased wear, and reduced fuel efficiency. AMSOIL synthetic lubricants are engineered to withstand these demanding conditions, offering superior protection against wear, oxidation, and thermal breakdown that conventional oils cannot match. By selecting the right fluid specifications for this specific application, you ensure that critical components like the turbo shafts, variable valve timing system, and piston rings remain clean and fully lubricated, regardless of driving style or climate.

When performing maintenance on your Infiniti Q50, it is crucial to understand that the engine oil requirements are specific to the VR30DDTT engine architecture. The preferred viscosity is 0W-20 for all operating temperatures. The total capacity for an oil change, including the AMSOIL Oil Filter, is 5.7 quarts. It is important to note the dipstick configuration; the standard 25-inch dipstick holds the full 5.7 quarts. If your vehicle has been fitted with a replacement 24.5-inch dipstick, you must add an additional 0.5 quarts (0.47 liters) to ensure the oil level is correct after refilling. Always verify the oil level after the refill. For the cooling system, the capacity varies significantly by trim level. The Intercooler requires 3.4 quarts. The standard model accommodates 9.3 quarts, the Sport model takes 9.3 quarts, and the Red Sport variant requires a full 10.9 quarts to fill the system completely. Proper cooling is essential for the intercooler and engine to manage the heat loads produced by the twin-turbo setup. The AMSOIL Passenger Car & Light Truck Antifreeze & Coolant is ideal for this purpose, as is the AMSOIL Propylene Glycol Antifreeze and Engine Coolant for specific applications.
The transmission in the 2016 Q50 is a 7-speed automatic (RE7R01A), which demands a fluid capable of handling high torque and rapid shifts. A total fill for this transmission requires 10.6 quarts. While the factory fluid is adequate, AMSOIL Signature Series Fuel-Efficient 100% Synthetic Automatic Transmission Fluid offers superior thermal stability and shear resistance, ensuring smoother shift feel and extended component life, especially during spirited driving or towing. For the final drives, the front differential (GL-5 rated) requires 1.4 pints of AMSOIL SEVERE GEAR® 80W-90 100% Synthetic Gear Lube, while the rear differential needs 2.2 pints. The rear differential specifically requires synthetic oil. Depending on your driving conditions and the type of differential (limited slip or open), AMSOIL SEVERE GEAR® 75W-90 100% Synthetic Gear Lube is recommended to control wear and prevent thermal runaway. The transfer case, if equipped, holds 2.1 pints and requires its specific lubricant, which can be the AMSOIL OE Multi-Vehicle 100% Synthetic Automatic Transmission Fluid. Finally, the braking system utilizes hydraulic fluid compatible with DOT 3 standards; AMSOIL DOT 3 and DOT 4 100% Synthetic Brake Fluid maintains a stable viscosity better than conventional fluids, enhancing pedal feel and safety in emergency stops.
About the Vehicle
The 2016 Infiniti Q50 represents a significant milestone in the brand’s history as the second generation of the Q50 sedan. This model year specifically features the introduction of the powerful 3.0-liter twin-turbocharged V6 engine, known internally as the VR30DDTT. This engine replaced the naturally aspirated V6 options found in earlier years and even offered more horsepower than the V8 found in the previous Q70 sedan. The VR30DDTT engine delivers a robust 300 horsepower in standard trims, with the Sport and Red Sport variants pushing that figure to 400 and 400+ horsepower respectively, depending on the specific trim and calibration. The vehicle sits on a rear-wheel-drive platform that was engineered for balance and agility, making the Q50 a compelling choice in the premium sport sedan segment.
Designed with a focus on “Zero Gravity” seating and a driver-centric cockpit, the 2016 Q50 aimed to compete directly with established German rivals like the Mercedes-Benz C-Class and BMW 3 Series. The addition of the Direct Adaptive Steering system in certain trims offered a unique driving characteristic, allowing for a variable steering ratio that adjusts based on speed and driver input, providing precise handling at low speeds and stability during high-speed maneuvers. The platform’s lightweight construction and aerodynamic efficiency contributed to its reputation for being both a comfortable daily driver and a capable cruiser for long-distance travel. The VR30DDTT engine, with its direct injection and twin-scroll turbos, was celebrated for its smooth power delivery and responsiveness, though it did require high-quality lubricants to manage the increased thermal loads associated with turbocharging. This generation of the Q50 solidified Infiniti’s commitment to performance and luxury, offering owners a sophisticated blend of Japanese engineering and American road comfort.
