The 2016 Subaru WRX 2.0L is a performance-oriented vehicle powered by the FA20F turbocharged engine. This specific engine configuration places significant thermal and mechanical stress on lubricants, requiring high-quality synthetic fluids to maintain reliability and performance. Unlike standard passenger cars, the WRX’s turbocharger operates at extreme temperatures, necessitating an oil that resists breakdown and provides a stable film strength under heavy load. Using the wrong fluid can lead to premature wear, reduced fuel economy, and potential failure of critical components like the timing chain and valve train.
Maintenance intervals for this vehicle should be followed strictly to ensure longevity. The engine requires 5.4 quarts of oil when performing a standard change with a filter replacement. The torque specification for the oil drain plug is 31 ft/lbs, and a new washer should always be installed on the drain bolt to prevent leaks. While the manufacturer specifies SAE 5W-30 as the primary viscosity for all temperatures, the use of high-quality AMSOIL Signature Series 5W-30 100% Synthetic Motor Oil is mandatory for this engine. If synthetic oil is temporarily unavailable, SAE 5W-40 conventional oil may be used, but it must be replaced with AMSOIL Extended-Life 5W-30 100% Synthetic Motor Oil at the next scheduled oil change to avoid damage. Regular maintenance should also include the replacement of the AMSOIL Oil Filter and WIX Air Filter to ensure proper airflow and contaminant removal.

Understanding the specific fluid requirements for the 2016 Subaru WRX is crucial for maintaining the vehicle’s renowned handling and acceleration capabilities. The engine’s turbocharging system creates high internal pressures and temperatures that can quickly degrade inferior lubricants. By selecting the appropriate AMSOIL motor oil, owners ensure that the engine receives a protective barrier against sludge, varnish, and wear. This is particularly important for the FA20F engine, which relies on consistent oil flow to cool the turbocharger and lubricate the timing chain. Furthermore, the transmission fluid is vital for the smooth operation of the continuously variable transmission (CVT). Using AMSOIL 100% Synthetic CVT Fluid prevents slippage and overheating, which are common issues in high-performance driving scenarios.
The cooling system also plays a pivotal role in the WRX’s performance. With capacities of 8.7 quarts for the MT8 engine and 8.9 quarts for the CVT-equipped models, the correct AMSOIL Passenger Car & Light Truck Antifreeze & Coolant is essential to prevent freezing in winter or overheating during spirited driving. AMSOIL’s antifreeze formulations are designed to exceed OEM requirements, offering superior protection against corrosion and erosion, which can degrade the radiator and water pump over time. For the drivetrain, the front differential requires 3 pints of AMSOIL SEVERE GEAR® 75W-90 100% Synthetic Gear Lube, while the rear differential holds 1.7 pints. Choosing the right viscosity and type of AMSOIL SEVERE GEAR® 80W-90 100% Synthetic Gear Lube, whether 75W-90 or 80W-90, ensures that the limited-slip differentials operate smoothly without causing chatter or excessive wear.
Transmission and Drivetrain Maintenance
The 2016 Subaru WRX features distinct transmission options that require specific attention. For vehicles equipped with the TR690 automatic transmission, the total fill capacity is 13.1 quarts. It is recommended to use AMSOIL 100% Synthetic CVT Fluid to ensure optimal frictional properties. Manual transmission owners with the TY751 specification should use a GL-5 SAE 75W-90 oil, with a total capacity of 7 pints. While GL-5 SAE 75W-90 may be used as an alternative, owners should be aware that using a different type of oil may detract from driveability and fuel efficiency. The torque specifications for the manual transmission drain plug vary slightly by application, ranging from 33 to 52 ft/lbs, so it is essential to verify the specific requirement for the model. Additionally, the differential lubricants require precise capacities: the front final drive is for automatic transmission only, holding 3 pints, while the rear differential holds 1.7 pints. Proper filling and torqueing of drain plugs prevent leaks and ensure the longevity of the gearbox and differential gears.
Additional Fluids and Performance Additives
Maintenance of the 2016 WRX extends beyond oil and fluids. The hydraulic AMSOIL DOT 3 and DOT 4 100% Synthetic Brake Fluid should be replaced with AMSOIL DOT 3 and DOT 4 100% Synthetic Brake Fluid to maintain consistent pedal feel and stopping power. This fluid provides a stable viscosity over a wide temperature range, which is critical for a performance vehicle subject to heavy braking. For seasonal storage, AMSOIL AMSOIL Gasoline Stabilizer helps keep fuel fresh for up to 12 months, protecting against varnish and gum buildup. Additionally, AMSOIL P.i.® AMSOIL P.i.® Performance Improver Gasoline Additive can restore up to 14% horsepower and clean GDI fuel injectors. This additive is particularly beneficial for maintaining fuel economy and preventing carbon buildup in the intake valves, a common issue in direct injection engines.
Vehicle Background and Model History
The 2016 Subaru WRX represents a pivotal year in the evolution of the legendary WRX line. This model marked the transition to the new “Crossover” generation, known internally as the VA series, which introduced a stiffer chassis and more sophisticated suspension geometry compared to its predecessor. The vehicle is powered by the FA20F engine, a 2.0-liter turbocharged flat-four boxer engine that replaced the older EJ20. This engine change was significant, offering better fuel efficiency and reliability while still delivering the spirited performance enthusiasts expect. The FA20F produces around 268 horsepower and 258 lb-ft of torque, providing a responsive and engaging driving experience.
Subaru’s signature Symmetrical All-Wheel Drive system is standard on the WRX, distributing power evenly between the front and rear wheels to maximize traction in all weather conditions. This system, combined with the low center of gravity inherent in the boxer engine layout, gives the WRX a unique handling character that rivals many sports cars. The WRX is renowned for its rally-bred heritage, designed for both track performance and daily drivability. Owners appreciate the vehicle’s practicality as a sedan, offering four doors and a decent trunk space, making it a versatile choice for those who enjoy spirited driving but also need a reliable daily commuter. The 2016 model year solidified Subaru’s reputation for building high-performance vehicles that prioritize durability and safety alongside speed.
The WRX’s market position is unique, appealing to a demographic that values both performance and all-weather capability. It is often compared to other hot hatchbacks and sports sedans but stands out due to its standard all-wheel drive. The vehicle’s reputation for ruggedness and long-term reliability has helped it maintain a strong resale value. For owners, regular maintenance is key to unlocking the full potential of the WRX. By adhering to recommended service intervals and using high-quality synthetic lubricants, owners can ensure that their WRX continues to deliver the dynamic driving experience it was designed for, year after year. Whether tackling winding mountain roads or navigating city traffic, the WRX remains a favorite among driving enthusiasts.
