What transmission fluid does a Subaru Outback use?

In brief, the correct fluid depends on the transmission in your Outback. Modern Outbacks with a CVT use Subaru CVTF; automatics use the appropriate ATF for their year and model; manuals require Subaru’s manual transmission fluid. Always check your exact year and model in the owner’s manual or with a Subaru dealer to confirm the correct specification.

Overview of transmission types in the Outback

Subaru Outbacks have evolved through the years. Most current models use a continuously variable transmission (CVT) called Lineartronic, while some older trims used traditional automatics or, in earlier generations, a manual transmission. The fluid you should use depends on which transmission your vehicle has.

Transmission fluids by type

The following guidance covers the common cases you’ll encounter in Outbacks across model years. Use it as a starting point, then verify against your owner’s manual for your specific year and engine.

• CVT (Lineartronic): Subaru CVTF (CVT fluid) specifically formulated for Subaru CVTs


• Automatic transmissions (older 4EAT-era or similar): ATF compatible with the transmission’s specification (often Dexron II/III compatibility; newer advisories may allow Dexron VI where specified)


• Manual transmissions: Subaru manual transmission fluid (MTF) meeting the OEM spec (often a GL-4-type gear oil or equivalent)

Note: Do not mix transmission fluids, and always use the specification listed in your owner’s manual. Using the wrong fluid can affect shifting, lubrication, and warranty coverage.

Practical tips for maintenance

To ensure you’re using the right fluid and maintaining it properly, follow these steps: check your manual for the exact fluid grade and capacity, confirm intervals for drain-and-fill or full flush, and use genuine Subaru fluids when possible. If you’re unsure, contact a Subaru-certified technician or your local dealer for guidance tailored to your VIN.

Summary

The Subaru Outback’s required transmission fluid depends on the transmission type: CVT models use Subaru CVTF, automatics use the ATF specified for their year/model (often Dexron II/III or Dexron VI), and manual transmissions require Subaru MTF per OEM specs. Always verify the exact specification for your vehicle’s year and transmission in the owner’s manual or with a Subaru service professional.

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.

What type of CVT fluid does Subaru use?

Idemitsu brand fluid is what Subaru uses as their OEM fluid, and can be had for less than the Subaru-branded stuff, which is exactly the same. Amsoil, Valvoline, Castrol all make CVT fluid that meet Subaru specs. Stick to subaru unless you drain the entire cvt which is impossible just from removing the drain plug.

What kind of transmission fluid does a 2016 Subaru Outback take?

The 2016 Subaru Outback uses one of two types of transmission fluid, depending on the transmission type. Vehicles with a Continuously Variable Transmission (CVT) require a specific Subaru CVTF-II or a compatible alternative like ENEOS ECO CVTF. Vehicles with a traditional automatic transmission (4EAT/5EAT) use Subaru ATF HP/PS fluid or a fluid specified by the vehicle's owner's manual. Always check the owner's manual or the vehicle's dipstick to confirm the correct type before adding fluid.
 
For CVT transmissions

• Subaru Genuine CVTF-II: This is the manufacturer-recommended fluid for the CVT. 
• Compatible Alternatives: If using an aftermarket fluid, choose one specifically designed for Subaru CVT transmissions, such as ENEOS ECO CVTF or ENEOS Import CVTF Model S, to avoid damage. 

For traditional automatic transmissions

• Subaru ATF HP/PS Fluid: This is the recommended fluid for the older 4EAT and 5EAT automatic transmissions. 
• Other Options: Some sources suggest using fluids like Valvoline DEX/MERC Conventional Automatic Transmission Fluid or Valvoline DEXRON-VI/MERCON LV Full Synthetic Automatic Transmission Fluid for traditional automatic transmissions, but confirm with your owner's manual. 

Important considerations

• Verify your transmission type: It is critical to confirm whether your specific 2016 Outback has a CVT or a traditional automatic transmission before purchasing fluid, as using the wrong fluid can cause severe damage.
• Consult your owner's manual: Always refer to your owner's manual for the most accurate and specific information for your vehicle's fluid requirements.
