Subaru Transmission Fluid Types
Subaru vehicles use different types of transmission fluid depending on the transmission system. Here are the types of transmission fluids used in Subaru vehicles:
1. Manual Transmission Fluid: Subaru manual transmission fluids meet different API GL standards. The ones currently commercialized are API GL-4 and API GL-5. It is important to choose the correct oil based on the recommended standard for your Subaru. If the recommended standard is GL-4, use a GL-4 oil to avoid damaging the bronze synchronizers with the sulfur found in GL-5 oils.
2. Automatic Transmission Fluid (ATF): Subaru automatic transmission fluids are usually called ATF. It is recommended to always use the type of oil recommended in the owner’s manual of your Subaru. If you are unsure, you can refer to the following list as a guide. Using the wrong oil can potentially damage the transmission over time.
– For 4 & 5-speed Subaru automatic transmissions: Subaru OEM Automatic Transmission Fluid (ATF) is used. It is also used in all Subaru power steering systems.
– For 5-speed Subaru automatic transmissions: Transmax X, which is a premium automatic transmission fluid specifically designed for use in 5-speed Subaru vehicles, is used.
– For Subaru vehicles with a continuously variable transmission (CVT): Subaru uses CVT fluid, which is more commonly used currently and has a lifetime service life. However, it is important to note that CVT fluid is expensive.
It is always recommended to consult your owner’s manual or contact a Subaru dealership for the specific transmission fluid requirements for your Subaru vehicle.

Is CVT oil same as ATF?
No, absolutely not – unless your “automatic” is a CVT, and then you must use CVT fluid. ATF and CVT oils are chemically completely different fluids with different additives, base stocks, viscosities, friction coefficients, etc.
Do Subarus need transmission fluid change?
Subaru Transmission Fluid
If you don’t routinely change your fluids at least every 30,000 miles or so, you may find that your Subaru transmission will slip.
What kind of transmission fluid does Subaru take?
Valvoline – DEXRON®-VI ATF Full Synthetic Automatic Transmission Fluid, 1 Gallon (Part No. 883572)
What kind of oil does a Subaru manual transmission take?
Genuine Subaru Gear Oil Extra MT 75W-80 is uniquely formulated for Subaru manual transmissions. This low viscosity fluid reduces mixing resistance, enables efficient power transfer from engine to tires and provides improved fuel economy.
Does it matter what transmission fluid I use?
The type of transmission fluid you should use depends upon the make, model and year of your vehicle. For example, many General Motor cars will require a DEXRON fluid and Ford cars commonly specify a MERCON fluid. Always follow the vehicle manufacturer recommendation for proper fluid use and change interval.
What kind of oil do I need for my manual transmission?
Commonly recommended manual transmission fluid formulations include SAE 80W, 75W-90, 80W-90 and SAE 90. In some cases, a multi-grade engine oil or automatic transmission fluid may be recommended. However, a manual transmission fluid is typically the most optimal for manual transmissions.
What happens if I use ATF in a CVT transmission?
CVT fluid is specially formulated for the particular friction requirements of the steel band and pulleys. ATF is made for clutches. If you accidentally put ATF in a CVT, you will need to completely drain and flush the unit.
What fluid goes in a Subaru CVT?
After speaking to a Subaru Master Mechanics it seems like the Eneos Eco CVT Fluid is compatible. PN# 3026-300.
What kind of transmission fluid does a Subaru Forester manual take?
Genuine Subaru Gear Oil Extra MT 75W-80 is uniquely formulated for Subaru manual transmissions.
What happens if you put ATF fluid in a CVT transmission?
Continuously Variable Transmission Fluids
One should never mix regular manual or automatic transmission fluid with CVT fluid or vice versa. While an advanced car can run with the wrong transmission fluid, it will end in damage.
