2024 Subaru Crosstrek Fluid Type Specs

Quick reference

Engine Oil

The 2024 Subaru Crosstrek, regardless of engine (2.0L or 2.5L BOXER), requires 0W-20 full synthetic engine oil. It is crucial to use oil that meets or exceeds the API SP and ILSAC GF-6B standards. These certifications ensure the oil provides superior protection against low-speed pre-ignition (LSPI), timing chain wear, and delivers improved fuel economy.

Capacity: Approximately 4.2 US quarts (3.9 liters) with a new filter. Always verify the level with the dipstick after a change.

Interval: Subaru recommends engine oil and filter changes every 6,000 miles or 6 months, whichever comes first. Refer to your owner's manual for specific severe service intervals if applicable.

Common Pitfalls: Do not use conventional or synthetic blend oils as they do not meet the full synthetic requirement and may not provide adequate protection. Using an oil with an incorrect viscosity (e.g., 5W-30) can lead to decreased fuel efficiency and potential engine wear over time.

Engine Coolant

The 2024 Subaru Crosstrek utilizes Subaru Super Coolant (SLLC), which is a blue, long-life, silicate-free, organic acid technology (OAT) coolant. This coolant is designed for extended service intervals and specific corrosion protection for Subaru's engine components.

Capacity: The total cooling system capacity is approximately 7.6 US quarts (7.2 liters).

Interval: The initial replacement for Subaru Super Coolant is typically 137,500 miles or 11 years, then every 75,000 miles or 6 years thereafter. Always consult your owner's manual for the most accurate and up-to-date information.

Common Pitfalls: Never mix Subaru Super Coolant with other types of coolant (e.g., green conventional, yellow HOAT, or other OAT coolants). Mixing different coolant types can lead to chemical reactions, reduced corrosion protection, premature wear of cooling system components, and gelling. Always use Subaru Genuine Super Coolant or an approved equivalent blue OAT coolant specifically formulated for Subaru vehicles.

Transmission Fluid (Continuously Variable Transmission - CVT)

All 2024 Subaru Crosstrek models are equipped with a Continuously Variable Transmission (CVT). The CVT requires Subaru CVTF-II (Continuously Variable Transmission Fluid - II) or an equivalent fluid that meets Subaru's specifications. This fluid is specifically engineered for the unique demands of the Lineartronic CVT.

Capacity: The fill capacity for a drain and refill is typically in the range of 6.9-7.2 US quarts (6.5-6.8 liters). A complete overhaul or dry fill capacity will be higher. The CVT does not have a traditional dipstick for owners to check, so servicing is typically done by a qualified technician.

Interval: Subaru generally considers the CVT fluid as a
