Does a Subaru need special transmission fluid?
Yes, Subaru vehicles do require the use of a specific type of transmission fluid. Subaru recommends using a Subaru-approved transmission fluid for optimal performance and longevity of the transmission system.
Subaru Transmission Fluid Requirements
Subaru vehicles are equipped with either a manual or automatic transmission, and each type requires a different type of transmission fluid. For manual transmissions, Subaru recommends using a GL-4 or GL-5 gear oil that meets the Subaru specifications. For automatic transmissions, Subaru specifies the use of a Subaru-approved automatic transmission fluid (ATF).
The Subaru-approved transmission fluids are designed to provide the necessary lubrication, wear protection, and performance characteristics required for Subaru's transmission systems. Using a non-approved fluid can lead to premature wear, reduced fuel efficiency, and even transmission failure.
Why Subaru Transmission Fluid is Important
Subaru's transmission systems are engineered to work optimally with the specified transmission fluids. These fluids have unique additive packages and viscosity characteristics that:
- Provide proper lubrication and wear protection for the gears and bearings
- Maintain the correct fluid viscosity for efficient power transmission
- Prevent the formation of sludge and deposits that can clog the transmission
- Ensure smooth and responsive shifting performance
Using a non-approved fluid can compromise these critical functions, leading to premature transmission wear and potential failure over time.
Replacing Subaru Transmission Fluid
Subaru recommends changing the transmission fluid at regular intervals, typically every 30,000 to 60,000 miles, depending on the model and driving conditions. It's important to use the exact Subaru-approved fluid specified in the owner's manual and to have the fluid change performed by a qualified technician to ensure the proper fluid level and condition.
Maintaining the correct Subaru transmission fluid is essential for the long-term health and performance of your Subaru's transmission system. Neglecting this important maintenance item can lead to costly repairs down the road.
Do CVT transmissions need special fluid?
Not all transmission fluids are created equal, and CVTs require specially formulated fluid to function properly. Using standard automatic transmission fluid (ATF) or a generic substitute can result in poor performance and irreversible damage.

Maintenance Insights for Subaru's CVT Transmission
The CVT transmission will require fluid flush occasionally to ensure smooth operation and prevent wear and tear. Also, the CVT belt might need replacement if it becomes stretched over time due to continuous movement.
Does Subaru need special transmission fluid?
Using the wrong fluid can cause severe damage to your transmission. Always use Subaru-approved CVT fluid or a compatible high-quality alternative like ENEOS ECO CVTF or ENEOS Import CVTF Model S.
What kind of ATF does Subaru use?
The Subaru transmission fluid type depends on your transmission, but common options include CVTF-II or CVTF-III for Continuously Variable Transmissions (CVTs) and ATF-HP for older automatic transmissions. It is crucial to use the correct fluid, so always consult your owner's manual or a Subaru dealership to confirm the specific type for your vehicle to prevent damage.
For Continuously Variable Transmissions (CVT)
- CVTF-II: A green fluid used in many older CVT models, such as certain Crosstrek, Forester, Legacy, and Impreza models.
- CVTF-III: A newer fluid for many current CVT models.
For Automatic Transmissions (AT)
- ATF-HP: A specific fluid recommended for many Subaru 4-speed and 5-speed automatic transmissions. It is also sometimes used in power steering systems.
- Dexron: Some older models may use a standard Dexron-type automatic transmission fluid.
Important considerations
- Owner's manual: Always check your owner's manual for the precise fluid type and specifications for your vehicle.
- Genuine Subaru fluid: It is highly recommended to use genuine Subaru fluid or an equivalent fluid from a trusted brand like Idemitsu, as Subaru uses Idemitsu as their OEM supplier.
- Avoid multi-vehicle fluids: Avoid using generic multi-vehicle fluids, especially for CVT transmissions, as they may not have the correct specifications.
