What ATF does Subaru use?

Subaru uses different automatic transmission fluids depending on the transmission type and model year. For CVTs (Lineartronic), Subaru specifies its own CVT fluid. For traditional automatics, the specification varies, typically Dexron VI or Subaru ATF WS, and older models may use Dexron II/III. Always refer to the owner's manual for the exact fluid specification for your vehicle.

Two main transmission fluid families in Subaru vehicles

Subaru classifies transmission fluids by transmission type rather than offering a single universal specification. The following outlines the fluids typically associated with each transmission family.

CVT (Lineartronic) fluids

This list covers the fluid used for Subaru's continuously variable transmissions, known as Lineartronic CVTs, which require a fluid formulated specifically for CVTs.

• Subaru CVT Fluid (CVTF) – the fluid specified by Subaru for most Lineartronic CVTs.

Using anything other than the CVT Fluid designed for your Subaru CVT can affect performance and wear, so always use the exact CVTF specified by Subaru for your model/year.

Automatic transmissions (non-CVT)

For traditional automatic transmissions in Subaru models, fluid compatibility has evolved with transmission design. Some older models used Dexron II/III; newer models commonly use Dexron VI or Subaru ATF WS, depending on model year and transmission type.

• Dexron VI – a modern specification that is compatible with many Subaru automatics that formerly called for Dexron II/III.


• Subaru ATF WS (World Standard) – used in newer Subaru automatic transmissions as an OEM fluid option.


• Dexron II/III – an older specification still found in some legacy Subaru automatics; use only if your owner's manual calls for it.

Note: Always confirm the exact ATF specification for your vehicle’s year and model in the owner's manual or via a Subaru dealer or service bulletin.

Regional variations and how to identify the correct ATF

Fluid specifications can vary by market, model year, and transmission type. The best approach is to verify with the official documentation for your car or consult a Subaru service professional.

• Check the owner's manual: Look for transmission fluid specifications and required service procedures.


• Check the fill cap or dipstick: Some Subaru models display the fluid spec near the transmission fill port or on the dipstick.


• Consult a dealer or certified shop: If in doubt, ask a Subaru service advisor to confirm the correct ATF for your VIN.

Using the wrong ATF can lead to reduced shifting performance, wear, or CVT damage in CVT-equipped models.

Summary

Subaru uses two main classes of transmission fluids: CVT Fluid (CVTF) for Lineartronic CVTs and various ATF formulations for traditional automatics. The most common modern choice for automatics is Dexron VI, though Dexron II/III may appear in older vehicles, and Subaru ATF WS is used in some newer transmissions. Always follow the model-year specific guidance in the owner's manual or from Subaru to ensure compatibility and optimal performance.

What transmission fluid does a Subaru Forester take?

A Subaru Forester takes either Subaru ATF HP for automatic transmissions or Subaru CVT Fluid for CVT transmissions. It is essential to use the correct fluid for your specific transmission type, as using the wrong one can lead to shifting issues or premature failure. Always consult your owner's manual or a parts specialist to confirm the exact fluid needed, as older models may use different types, such as those compatible with Dexron VI.
 
For automatic transmissions

• Use Subaru ATF HP or its equivalent, such as Idemitsu ATF HP. 
• This is a specialized fluid designed to work with Subaru's automatic transmissions to ensure proper shift quality and protection. 
• Some models may also be compatible with Dexron VI or Dexron III, but check your owner's manual. 

For CVT transmissions

• Use Subaru CVT Fluid or its equivalent. 
• This fluid has a different formulation than ATF and is specifically designed for Subaru's Continuously Variable Transmissions. 
• Some universal fluids may specify compatibility with Subaru CVT transmissions, but verify this before using one. 

Important considerations

• Consult your owner's manual: This is the most reliable source for determining the correct transmission fluid for your specific Subaru Forester model and year. 
• Consider a partial fill: Since a full drain and refill may not remove all the old fluid, some owners recommend doing a series of three drain and fills to ensure a higher percentage of the new fluid is in the system. 
• Preventative maintenance: For older models, changing the transmission fluid as recommended in the owner's manual is crucial for long-term durability. 

What automatic transmission does Subaru use?

Lineartronic® CVT
Lineartronic® CVT, or Continuously Variable Transmission, is the type of automatic transmission used across the Subaru line-up.

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. 

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.
