What oil is recommended for a Subaru?
Choosing the right oil for your Subaru is crucial for maintaining its performance and longevity. With various models and engine types, the oil specifications can vary. In this article, we will explore the recommended oil types for different Subaru vehicles, ensuring you make an informed decision for your car's needs.
Understanding Subaru's Oil Requirements
Subaru vehicles are known for their unique engineering, particularly their boxer engines. This design requires specific oil types to ensure optimal performance. Here are the key factors to consider:
- Viscosity: Most Subaru models recommend using 0W-20 synthetic oil, especially for newer models. This oil provides excellent flow at low temperatures and maintains viscosity at high temperatures.
- API Certification: Look for oil that meets the API (American Petroleum Institute) certification standards. Oils with the "SN" or "SP" rating are suitable for most Subaru engines.
- Subaru's Own Oil: Subaru also offers its own brand of synthetic oil, which is specifically formulated for their engines. Using Subaru's oil can help maintain warranty coverage and ensure compatibility.
Oil Recommendations by Model
Different Subaru models may have varying oil requirements. Here’s a quick guide:
- Subaru Impreza: 0W-20 synthetic oil is recommended for both the 2.0L and 2.5L engines.
- Subaru Outback: For the 2.5L engine, 0W-20 synthetic oil is ideal, while the 3.6L engine may require 5W-30 synthetic oil.
- Subaru Forester: Similar to the Outback, the 2.5L engine benefits from 0W-20 synthetic oil, while the turbocharged models may require different specifications.
- Subaru Legacy: The 2.5L engine typically uses 0W-20 synthetic oil, while the 3.6L engine may require 5W-30.
Conclusion
Using the correct oil for your Subaru is essential for its performance and longevity. Always refer to your owner's manual for the most accurate specifications and consider consulting with a professional mechanic if you're unsure. Regular oil changes with the right oil will help keep your Subaru running smoothly for years to come.
Frequently Asked Questions
Can I use 5W-30 instead of 0W-20 Subaru?
Synthetic oil-specifically 0W-20-is highly recommended for optimal engine performance and protection. If synthetic oil isn't available at the time of an oil change, 5W-30 conventional oil may be used instead. However, it should be replaced with synthetic oil at the next change.
What oil does Subaru prefer?
Most new Subaru vehicles require synthetic oil with a viscosity rating of 0W-20.
What is the best oil to run in a Subaru?
Subaru Oil Guide:
| Model | Subaru Oil Required | Capacity |
|---|---|---|
| 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 |
| Subaru Crosstrek Hybrid 2014 - 2021 | 0W-20 Synthetic Oil | 4.4 - 5.1 Quarts |
| Subaru Ascent 2019 - 2021 | 0W-20 Synthetic Oil | 4.8 Quarts |
Is it OK if I put 5w20 instead of 0w20?
If SAE 0W-20 synthetic oil is not available, SAE 5W-20 conventional oil may be used. However, it must be replaced with SAE 0W-20 synthetic oil at the next oil change.
Is it OK to use 5W 20 instead of 0W-20?
If SAE 0W-20 synthetic oil is not available, SAE 5W-20 conventional oil may be used. However, it must be replaced with SAE 0W-20 synthetic oil at the next oil change.
Do subarus require full synthetic oil?
Naturally aspirated engines in the newest Forester, Impreza, Legacy, Outback, and BRZ models as well as turbocharged models require Subaru Synthetic Motor Oil (or its equivalent).
Can I put 5W-30 in a Subaru Forester?
Any Subaru Forester after 2011 requires synthetic oil. Newer models after 2011 with a non-turbocharged engine take 0W-20 oil, whereas turbocharged engine models require 5W-30 oil. Get a breakdown of the recommended Subaru Forester oil types below: Subaru Forester 2002 to 2010: 5W-30 Conventional Oil.
What is the recommended engine oil for Subaru?
Subaru Oil Guide:
| Model | Subaru Oil Required | Capacity |
|---|---|---|
| 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 |
| Subaru Crosstrek Hybrid 2014 - 2021 | 0W-20 Synthetic Oil | 4.4 - 5.1 Quarts |
| Subaru Ascent 2019 - 2021 | 0W-20 Synthetic Oil | 4.8 Quarts |
Why does Subaru use 0W-20 oil?
The 0W-20 is the perfect weight for he non-turbo engine and is formulated for improved fuel economy.
What happens if you put regular oil in a car that requires synthetic?
Answer. Synthetic oils typically provide better protection than conventional oils, but switching back and forth between full synthetic and conventional oil will not damage the engine. Of course, this depends on the current engine condition and the quality of the conventional oil being used.
