Engine Oil

• Specification: API SN or SP, ILSAC GF-5 or GF-6
• Viscosity: 0W-20
• Capacity: 4.4 quarts (2.0L FB20D engine) / 5.1 quarts (2.5L FB25D engine)

The 2022 Crosstrek, whether equipped with the 2.0L or the 2.5L engine, requires a high-quality synthetic 0W-20 motor oil. Subaru specifies an oil that meets the American Petroleum Institute (API) classification SN or the newer SP standard. Using the correct viscosity is critical for the proper operation of Subaru's variable valve timing (AVCS) system and for ensuring optimal fuel economy and engine protection in all temperatures.

While many high-quality synthetic 0W-20 oils will meet these specs, the official recommendation is to use Genuine Subaru Synthetic Motor Oil. Always verify the API donut on the bottle. Oil and filter change intervals are typically every 6,000 miles or 6 months, but this can vary based on driving conditions. Consult your owner's manual for the severe service interval if you frequently drive in dusty conditions, make short trips, or tow.

Engine Coolant

• Specification: Subaru Super Coolant (Blue)
• Type: Phosphated Organic Acid Technology (P-OAT)
• Capacity: 7.6 - 8.7 quarts (total system)

Subaru utilizes a specific blue P-OAT coolant, branded as "Subaru Super Coolant." It is crucial to use only this specific type of coolant. Mixing it with other coolant types (like green IAT or orange OAT/HOAT) can cause a chemical reaction that leads to gelling, which can clog the radiator, heater core, and cooling passages, resulting in severe engine damage.

Never use "universal" or "all makes, all models" coolant. If you need to top off the system, use only Subaru Super Coolant or an equivalent P-OAT formula specifically designed for modern Asian vehicles. The initial factory fill is designed to last for over 100,000 miles, but it's wise to inspect the level and condition in the overflow reservoir regularly.

Transmission Fluid

Continuously Variable Transmission (CVT)

• Specification: Subaru High Torque CVTF (Lineartronic TR580/TR690)
• Capacity: Approximately 12.9 quarts (service refill will be less)

Crosstreks equipped with the CVT require a very specific fluid: Subaru High Torque CVTF. The use of any other ATF, "universal" CVT fluid, or even other types of Subaru CVT fluid is strictly prohibited. The Lineartronic CVT operates under unique pressures and requires precise frictional properties that only the OEM fluid can provide. Using the wrong fluid will almost certainly lead to shuddering, slipping, and premature transmission failure, resulting in a multi-thousand dollar repair.

Subaru considers this a "lifetime" fluid, but many independent specialists recommend a drain and fill service between 60,000 and 100,000 miles to ensure longevity, especially if the vehicle is used for towing or driven in mountainous terrain.

Manual Transmission

• Specification: Subaru Extra MT 75W-80 GL-5
• Capacity: 3.5 quarts

For the increasingly rare 6-speed manual models, the required fluid is Subaru Extra MT 75W-80. This is a specific gear oil formulated for smooth shifting and proper synchronizer engagement. While other 75W-80 GL-5 gear oils exist, using the OEM fluid is the best way to guarantee smooth operation in all temperatures.

Front & Rear Differential Gear Oil

• Specification: Subaru High Performance 75W-90 Gear Oil (API GL-5)
• Capacity (Front): 1.4 - 1.5 quarts
• Capacity (Rear): 0.8 quarts

The front and rear differentials on a Crosstrek (which is full-time AWD) require a high-quality hypoid gear oil. The factory specification is API GL-5 75W-90. The front differential is integrated with the transaxle, but the fluid is separate from the main transmission fluid (for both CVT and manual models). The rear differential is a separate unit.

It is critical to use a fluid meeting the API GL-5 standard to provide the necessary extreme pressure (EP) protection for the hypoid gear set. For most Crosstrek models, a limited-slip additive is not required. Inspecting and changing this fluid every 30,000-60,000 miles is good practice, especially if the vehicle sees severe duty.

Brake Fluid

• Specification: DOT 3 or DOT 4
• Capacity: As needed (typically 1-2 quarts for a full flush)

Subaru specifies standard DOT 3 or DOT 4 brake fluid. The two are compatible and can be mixed, though DOT 4 has a higher boiling point, which is beneficial for performance driving or towing. Never use DOT 5 fluid, as it is silicone-based and completely incompatible with the DOT 3/4 (glycol-ether based) system. Contamination will damage the brake system seals.

Brake fluid is hygroscopic, meaning it absorbs moisture from the air over time. This moisture lowers the boiling point and can cause corrosion inside the brake lines and calipers. For this reason, it should be flushed and replaced every 2-3 years, regardless of mileage.

Power Steering Fluid

The 2022 Subaru Crosstrek is equipped with an Electric Power Steering (EPS) system. It does not have a hydraulic power steering pump or use any power steering fluid.

Windshield Washer Fluid

• Specification: Any commercial windshield washer fluid
• Capacity: Approximately 4.2 quarts

There is no special requirement for washer fluid. Use any quality commercial fluid, and consider a de-icing formula for winter months to prevent freezing on the windshield and in the lines.
