When performing maintenance on the 2016 Infiniti Q50 2.0L Turbo, understanding the specific fluid capacities and viscosity requirements is crucial for proper lubrication. The engine, identified by the code 1991 cc 0 Turbo, requires a precise amount of AMSOIL 5W-40 FS 100% Synthetic European Motor Oil or AMSOIL 0W-40 FS 100% Synthetic European Motor Oil to function correctly. For a standard oil change including the AMSOIL oil filter, the capacity is 7 quarts, though some sources indicate a capacity of 6.7 quarts depending on the specific service procedure. Regardless of the exact volume, it is essential to check the oil level after refill. The drain plug torque specification is 30 ft/lbs, and a new washer should always be installed on the drain bolt to prevent leaks.
For those opting for the 0W-30 viscosity grade, the temperature range covers all conditions. The 5W-40 variant is suitable for temperatures above -25°C. The choice between the AMSOIL 5W-40 FS and 0W-40 FS European Motor Oils depends on your local climate and driving style. Both fluids are 100% synthetic and feature a European formula with a precise blend of synthetic base oils and premium additives. These oils are designed to handle the unique thermal stresses of turbocharged engines, providing superior engine cleanliness and viscosity control compared to conventional oils.
Moving beyond the engine, the automatic transmission in this Q50 model utilizes the RE7R01A (SL083) fluid specification. A total fill for the 7-speed automatic transmission requires 10.7 quarts, while a standard service involves a specific fluid exchange. Using AMSOIL Signature Series Fuel-Efficient or OE Fuel-Efficient Automatic Transmission Fluids ensures the transmission remains fluid in sub-zero temperatures while providing reserve protection during heavy use. These fluids protect against wear, sludge, and temperature-related problems, allowing the driver to drive with confidence even under severe conditions.
The cooling system for the 2016 Infiniti Q50 2.0L has a capacity of 9.5 quarts. Maintaining the correct AMSOIL Propylene Glycol Antifreeze and Engine Coolant mixture is vital to prevent overheating and corrosion. AMSOIL Passenger Car & Light Truck Antifreeze & Coolant and the AMSOIL Propylene Glycol Antifreeze and Engine Coolant offer distinct benefits. The OAT formulation in the Passenger Car & Light Truck option is phosphate-, nitrate-, nitrite-, silicate-, borate-, and amine-free, making it compatible with all other antifreeze colors while protecting gaskets and hoses. The Propylene Glycol option is a concentrated formula that requires mixing with distilled water and offers protection up to 150,000 miles or 5 years, significantly surpassing standards for metallic corrosion and erosion.
Differential and Transfer Case Lubrication
Proper gear lubrication is often overlooked but essential for the longevity of the drivetrain. The front differential requires 1.4 pints of lubricant, while the rear differential requires 2.2 pints. For the front differential, which operates under high load, AMSOIL SEVERE GEAR® 80W-90 is a highly effective 100% synthetic gear lube. It controls thermal runaway and helps reduce operating temperatures. For the rear differential and the transfer case, which requires 2.1 pints, the AMSOIL SEVERE GEAR® 75W-90 is the recommended choice. This fluid contains friction modifiers for limited-slip applications and offers long oil, seal, and equipment life. Alternatively, AMSOIL SEVERE GEAR® 75W-90 or AMSOIL SEVERE GEAR® 75W-110 can be used for the rear differential. For the transfer case specifically, the drain plug torque is 26 ft/lbs, and the fill plug torque is also 26 ft/lbs. A new washer must be installed on both bolts. Synthetic oil is required for the transfer case, making the 100% synthetic AMSOIL SEVERE GEAR® gear lubes the ideal solution. These products resist the harsh conditions of shifting and heavy loads, ensuring smooth power delivery and preventing premature wear on the gears and bearings.
Brake system safety is paramount, and for the Q50, the hydraulic AMSOIL DOT 3 and DOT 4 100% Synthetic Brake Fluid should meet DOT 3 or DOT 4 standards. AMSOIL DOT 3 and DOT 4 100% Synthetic Brake Fluid provides excellent responsiveness for ABS and traction control systems. Its stable viscosity over a wide temperature range ensures consistent braking performance, regardless of whether you are driving in the dead of winter or on a hot summer day. This synthetic fluid helps maintain the integrity of the brake system, reducing the risk of brake fade and improving overall safety.
