Which Cars, How Often, Exceptions-Subaru

It used to be that Synthetic Oil was used primarily in the aviation and aerospace industry. Considering the many benefits of synthetic oil, it’s no wonder the automotive industry caught on. Most new Subarus now come with and require Synthetic Oil for optimum performance and protection.

Recommended Oil by Model – Straight Answers From the Owners’ Manuals

Subaru Model

What the Owner’s Manual Says*

Subaru Forester
2011 and Newer
2.5i
0W-20 synthetic oil is the required oil for optimum engine performance and protection. Conventional oil may be used if synthetic oil is unavailable. If 0W-20 synthetic oil is not available, 5W-30 or 5W-40 conventional oil may be used if replenishment is needed but should be changed to 0W-20 synthetic oil at the next oil change.
2.5 XT (2011-2013)
2.0 XT (2014)
5W-30 synthetic oil is required for optimum engine performance and protection. Conventional oil may be used if synthetic oil is unavailable. If 5W-30 synthetic oil is not available, 5W-30 or 5W-40 conventional oil may be used if replenishment is needed but should be changed to 5W-30 synthetic oil at the next oil change.
Subaru Outback/Legacy
2013 and Newer
2.5i
0W-20 synthetic oil is the required oil for optimum engine performance and protection. Conventional oil may be used if synthetic oil is unavailable. If 0W-20 synthetic oil is not available, 5W-30 or 5W-40 conventional oil may be used if replenishment is needed but should be changed to 0W-20 synthetic oil at the next oil change.

3.6R

Your vehicle is designed to use 5W-30 conventional motor oil, however 5W-30 synthetic may be used for optimum engine performance. If you do choose to use synthetic oil, we recommend that you continue using synthetic for the life of your vehicle.
Subaru Impreza
2012 and Newer
ALL
0W-20 synthetic oil is the required oil for optimum engine performance and protection. Conventional oil may be used if synthetic oil is unavailable. If 0W-20 synthetic oil is not available, 5W-30 or 5W-40 conventional oil may be used if replenishment is needed but should be changed to 0W-20 synthetic oil at the next oil change.
Subaru XV
2013 and Newer

ALL Models

0W-20 synthetic oil is the required oil for optimum engine performance and protection. Conventional oil may be used if synthetic oil is unavailable. If 0W-20 synthetic oil is not available, 5W-30 or 5W-40 conventional oil may be used if replenishment is needed but should be changed to 0W-20 synthetic oil at the next oil change.
Subaru WRX-STI
2012 and Newer
ALL Models
5W-30 synthetic oil is the required oil for optimum engine performance and protection. Conventional oil may be used if synthetic oil is unavailable. 10W-30, 10W-40, 5W-30 or 5W-40 conventional oil may be used if replenishment is needed but should be changed to 5W-30 synthetic oil at the next oil change.
Subaru BRZ
2013 and Newer

ALL Models

SAE 0W-20 is the best choice for good fuel economy and good starting in cold weather.
NOTE: We are not sure what the manual means. BRZs come with 0W-20 Synthetic Oil and should follow the same recommendations as the Impreza or XV Crosstrek.
Subaru Tribeca
2013 and Newer
ALL Models
Your vehicle is designed to use 5W-30 conventional motor oil, however 5W-30 synthetic may be used for optimum engine performance. If you do choose to use synthetic oil, we recommend that you continue using synthetic for the life of your vehicle.

HELPFUL RULE OF THUMB: If your new Subaru has 6 cylinders, it uses 5W-30 conventional oil. If it’s a turbo, it uses 5W-30 synthetic oil.
All other new Subarus use 0W-20 synthetic oil.

Common Questions and Answers About Synthetic Motor Oil

What’s the difference between synthetic oil and conventional oil?

Conventional motor oil is a lubricant that is derived directly from crude oil. Over time, petroleum-based oils break down from heat and pressure inside the engine. Synthetic oil begins as conventional oil but is further refined and modified to improve its protective and lubricating properties providing better stability, reduced breakdown and fewer deposits.
What are the advantages and disadvantages of  Synthetic Motor Oil?
  • Better low and high temperature viscosity performance
  • Decreased evaporative loss
  • Resistance to oxidation, thermal breakdown, and oil sludge problems
  • Extended drain intervals with the environmental benefit of less oil waste.
  • Improved fuel economy in certain engine configurations.
  • Better lubrication during extreme cold weather starts
  • Longer engine life
  • Superior protection against “ash” and other deposit formation in engine hot spots (in particular in turbochargers and superchargers) for less oil burnoff and reduced chances of damaging oil passageway clogging.
  • Increased horsepower and torque due to less initial drag on engine

The ONLY disadvantage of using Synthetic Motor Oil is the added expense, however that is addressed below.
Does Subaru Synthetic Oil cost more?

YES and NO. Because of the refinement process, synthetic oil does cost more than conventional oil, but the benefits are certainly worth it. In addition, the oil change frequency is generally double the mileage of conventional oil. As more auto manufactures use synthetic oil, the price is coming down. Subaru dealers can now purchase Subaru Synthetic Oil in bulk quality vs. quart or gallon containers – further reducing cost. Manchester Subaru stocks the smaller containers for people wishing to change or top off their own oil.
Does it make my engine last longer?
Yes, because synthetic oil is so slippery, it makes for less engine wear and thus greater engine longevity.

Does Synthetic Oil require a separate (or special) oil filter?

No.  Synthetic Motor Oil works with the same/OEM filters used with conventional motor oils.
What happens if I mix conventional oil with Synthetic Oil?

In cases where you can not find the appropriate synthetic oil for your Subaru, you may combine the existing synthetic oil with conventional oil of the same viscosity.  However, the performance and benefits of  Synthetic Motor Oil will be degraded if mixed with regular oil. We recommends you change back to all synthetic oil on your next oil change.
