Using Synthetic Blend Oil in a Subaru
Yes, you can use a synthetic blend oil in your Subaru. However, it’s important to note that if your Subaru is a 2011 or newer Forester, a 2012 or newer Impreza, or a 2013 or newer Outback, Legacy, Crosstrek, or BRZ, or Ascent, it is required to use synthetic oil.
In an emergency situation, you can mix Subaru Synthetic Motor Oil with conventional motor oil, but it is best to not mix them, and the oil should be changed once you are out of the emergency situation. The performance and benefits of Subaru Synthetic Motor Oil will be degraded if mixed with regular oil.
It’s worth mentioning that synthetic blend oils are a mixture of both synthetic and conventional base oils, plus some additives. While chemically different, synthetic blend oil shares many characteristics of full synthetic oil.
So, while it is possible to use a synthetic blend oil in your Subaru, it’s important to consider the specific requirements for your model and the potential impact on performance and benefits if mixed with regular oil.

What are the disadvantages of synthetic blend oil?
Multi-grade motor oils using synthetics may exhibit slightly less fuel economy at highway speeds compared to mineral oil. The oil could leak out of old engines with loose seals and gaskets. This is due to lower pour pont and flowing characteristics even at low temperatures.
Can I use Mobil 1 in my Subaru?
Choose Mobil 1™ motor oil for your Subaru. We offer a full range of synthetic and synthetic blend motor oils to keep your engine in peak condition throughout its lifetime.
Do Subarus need special oil changes?
No. Subaru Synthetic Motor Oil works with the same Subaru filters used with conventional motor oils.
What is the best oil for Subarus?
Subaru Oil Guide:
| Model | Subaru Oil Required | Capacity |
|---|---|---|
| Subaru Legacy & Outback XT (Turbo) 2020 – 2021 | 0W-20 Synthetic Oil | 4.8 Quarts |
| Subaru WRX 2002 – 2010 | 5W-30 Conventional Oil | 4.4 – 5 Quarts |
| Subaru WRX 2011 – 2020 | 5W-30 Synthetic Oil | 4.4 – 5.4 Quarts |
| Subaru Crosstrek 2013 – 2021 | 0W-20 Synthetic Oil | 4.4 – 5.1 Quarts |
What oil does Subaru use from the factory?
Synthetic 0W-20 is uniquely formulated to handle the low-friction design of Subaru non-turbocharged engines. Synthetic 5W-30 motor oil is required for 2011 and newer turbo-charged engines, and is recommended for prior year models.
What type of oil should I put in my Subaru Outback?
Oil Type & Capacity for Subaru Outback
Like the Crosstrek, the oil for the Subaru Outback needs to be an API classification SN or ILSAC GF-5. Also like the Crosstrek, the Outback engine should be filled with 0W-20 synthetic oil. If synthetic oil isn’t available, you can use either 5W-30 or 5W-40 conventional oil.
Is it OK to use synthetic blend instead of synthetic?
Synthetic blend oil is more affordable but will not provide the same great performance that comes with full synthetic. No matter what vehicle you drive, it is almost always compatible with full synthetic or synthetic blend oils. Some exceptions do exist, mostly with older cars. So be sure to check your owners manual.
Can you tell the difference between full synthetic and synthetic blend?
Full synthetic oil uses higher quality base oils than the less-refined oil used in conventional oils, making its molecules more uniform in size with much fewer impurities. While synthetic blends and conventional oil use crude oil as their base, which is found to have more impurities.
What type of oil does a Subaru Outback take synthetic?
The Recommended Subaru Outback Oil Type
0W-20 Synthetic Oil: Recommended for 4-cylinder engines and most newer Subaru Outback models. This oil type ensures smooth engine operation in both cold and hot conditions. 5W-30 Synthetic Oil: Recommended for 6-cylinder engines.
Does Subaru Outback need full synthetic?
4-cylinder Subaru Outback models from 2002 to 2012 require a conventional oil blend, but any models after 2012 require synthetic oil. The same applies to 6-cylinder models, but models from 2002 to 2019 can take conventional, whereas models after 2019 and onward demand synthetic oil.
