What type of oil does Subaru use?
In most new Subaru models, the recommended oil is 0W-20 synthetic, though the exact grade can vary by engine and market. Always check your owner's manual for the precise specification for your vehicle.
Understanding Subaru oil viscosity by engine and market
Below is a general guide to the oil viscosities Subaru commonly specifies, noting when variations apply.
- Most modern Subaru gasoline engines (FA and FB families, including 2.0L and 2.5L engines used in models like the Forester, Outback, Legacy, and Impreza) are typically specified for 0W-20 synthetic oil. This viscosity supports efficient cold starts and fuel economy in a wide range of climates.
- Turbocharged or high-performance variants (such as certain WRX/STI models) may call for 5W-30 or 5W-40 synthetic oil depending on the model year, market, and operating climate. Always verify the exact grade for your specific car.
- In very warm climates or under heavy-duty driving conditions, some markets or engine configurations may permit 5W-30, but this is not universal. The manual or dealer guidance should determine if an alternative viscosity is allowed.
- Subaru generally recommends synthetic oil rather than conventional/mineral oil for modern engines, to maximize protection and performance. Always use a full synthetic oil that meets the required specifications.
- Oil spec requirements can change with updates to engines and regional guidelines. Oils should meet ILSAC and API standards (for example, API SN or newer and ILSAC GF-5/GF-6 or equivalent).
When in doubt, verify the exact grade and specification for your vehicle in the owner's manual or with a Subaru dealer, as the correct oil for your car depends on model year, engine type, and regional guidelines.
How to confirm the exact oil specification for your Subaru
To ensure you’re using the right oil for your Subaru, follow these steps:
- Check the owner's manual for the exact viscosity (for example, 0W-20) and the specification requirements (such as API/SN or SP and ILSAC GF-5/GF-6 or higher).
- Look at the engine oil filler cap; some caps display the recommended viscosity or grade.
- Consult Subaru’s official resources or your VIN-specific maintenance schedule on the Subaru Owner Site or contact a Subaru dealer for a precise recommendation.
- Choose a high-quality synthetic motor oil that meets the specified grade and standards (Subaru Genuine Motor Oil or an equivalent that meets the required specification).
- Follow the service interval guidelines for oil changes to maintain warranty coverage and engine health.
Ensuring you use the correct oil protects engine performance, longevity, and warranty compliance. If you’re unsure, a Subaru-certified technician can confirm the right viscosity and specification for your vehicle.
Summary
Most modern Subarus use a 0W-20 synthetic oil as the standard recommendation, but exact requirements can vary by engine, model year, and market. Always consult your owner's manual or a Subaru dealer to confirm the correct viscosity and specification for your vehicle, and choose a high-quality synthetic oil that meets those standards. Proper oil choice supports optimal performance, fuel efficiency, and engine protection.
