Keeping your 2016 Subaru Crosstrek 2.0L running smoothly requires more than just following a general maintenance schedule; it demands the precise fluids recommended for its specific engine and drivetrain configuration. The FB20 engine is sensitive to oil viscosity, and the vehicle’s unique All-Wheel Drive system places specific demands on its transmission and differentials. Using the correct lubricants ensures optimal performance, maximizes fuel economy, and protects critical components from the wear and tear associated with daily driving and varying weather conditions. Whether you are navigating city streets or tackling rougher terrain, the right fluids are your best defense against premature mechanical failure.

Understanding the lubrication requirements for the 2016 Subaru Crosstrek helps owners make informed decisions about maintenance intervals and fluid types. The engine requires SAE 0W-20 synthetic oil as the primary viscosity. If this specific grade is unavailable, the manufacturer notes that SAE 5W-30 or SAE 5W-40 conventional oil can be used temporarily, but it must be replaced with the proper synthetic 0W-20 at the next service. The total capacity for the 2.0L FB20 engine, including an oil filter change, is 5.1 quarts. Proper oil selection is critical not just for reducing friction, but for managing the heat generated by the engine and its turbocharger components. AMSOIL’s range of 0W-20 oils ensures that your vehicle receives the exact protection needed to maintain factory performance specifications while extending service intervals significantly beyond conventional recommendations.
The transmission system in the Crosstrek also demands specific attention. For the automatic transmission, identified as the TH58A, a total fill requires 14.9 quarts of fluid. This system relies heavily on the frictional properties of the transmission fluid to operate smoothly, especially since the Crosstrek utilizes a Continuously Variable Transmission (CVT) design. Using a dedicated synthetic CVT fluid helps maintain the precise friction coefficients required for the belt and pulley system to function without slippage or overheating. Standard transmission fluids often lack the necessary additives for CVT systems, making the use of a specialized synthetic fluid essential for long-term reliability. By using the correct fluid, you protect the transmission from wear, sludge buildup, and temperature-related degradation that can lead to costly repairs.
Protecting the Drivetrain and Cooling System
Because the 2016 Crosstrek is equipped with a full-time All-Wheel Drive system, the differential and transfer case lubrication play a vital role in vehicle handling and safety. The front differential requires 3 pints of GL-5 AMSOIL SEVERE GEAR® 75W-90, while the rear differential holds 1.7 pints. The viscosity requirements can vary based on the specific gear setup, with 75W-90 being a common specification for optimal performance in both temperature extremes and high-load situations. Synthetic gear lubes offer superior resistance to thermal breakdown and oxidation, ensuring that the gear teeth are adequately coated even under the stress of off-road driving or towing. These fluids also contain additives that prevent rust and corrosion, which is particularly important for vehicles exposed to road salt or moisture.
Beyond the drivetrain, the cooling system is the engine’s primary defense against overheating. The 2016 Crosstrek holds 8.7 quarts of AMSOIL Passenger Car & Light Truck Antifreeze & Coolant. Over time, traditional coolants can become acidic, leading to corrosion within the radiator, water pump, and engine block. AMSOIL’s antifreeze formulations are designed to exceed original equipment manufacturer requirements, offering up to 150,000 miles of protection. The Propylene Glycol option is a concentrated coolant that allows for flexibility in mixing ratios, while the Passenger Car & Light Truck Antifreeze comes pre-mixed for convenience. Both options are free from phosphates, nitrates, and nitrites, making them safe for all cooling system metals and compatible with other coolant colors. This ensures that the engine operates at its ideal temperature, preserving performance and fuel efficiency year-round.
Maintenance for Seasonal and Long-Term Use
Vehicle owners who use their Crosstrek for seasonal storage or long periods of inactivity should consider adding fuel stabilizers and fogging oils to their maintenance routine. AMSOIL Gasoline Stabilizer keeps fuel fresh for up to 12 months, fighting ethanol corrosion and preventing varnish buildup in the fuel system. This is particularly useful for owners who drive less frequently or store the vehicle during winter months. For engine preservation, the Engine Fogging Oil creates a protective coating on internal components, preventing rust during storage. Additionally, the P.i.® Performance Improver gasoline additive can restore up to 14% horsepower by cleaning fuel injectors and reducing carbon deposits, helping to maintain the engine’s original efficiency. These additives are compatible with capless fuel systems and work to prevent pre-ignition knock, ensuring the vehicle starts and runs smoothly even after extended periods of inactivity.
Brake System and Exterior Care
The safety of your vehicle is heavily reliant on the condition of the braking system. The Crosstrek uses hydraulic AMSOIL DOT 3 and DOT 4 100% Synthetic Brake Fluid meeting DOT 3 specifications. Over time, brake fluid absorbs moisture from the air, which lowers its boiling point and can lead to brake fade or corrosion in the brake lines. AMSOIL’s 100% Synthetic Brake Fluid maintains a stable viscosity over a wide temperature range and offers excellent responsiveness for ABS and traction control systems. Switching to a synthetic brake fluid can improve the feel of the brake pedal and extend the life of the braking components.
Keeping the exterior of the vehicle clean not only maintains its appearance but also protects the paint and metal surfaces from environmental damage. Products like the Miracle Wash provide a protective finish without the need for water, repelling dust and dirt while shielding against UV rays. For deeper cleaning, the Engine Degreaser and Heavy-Duty Degreaser remove stubborn grime and oil from engine bays and undercarriages. The Silicone Spray is ideal for preserving rubber seals and preventing drying or cracking. These care products complement the mechanical maintenance, ensuring that the vehicle is protected both internally and externally for maximum longevity.
