What kind of oil does a Subaru 2.5 L engine take?

The recommended oil for a Subaru 2.5L engine is 5W-30 synthetic motor oil. This oil weight and type provides the optimal lubrication and protection for the engine's components, ensuring proper performance and longevity.


Subaru 2.5L Engine Oil Specifications


Subaru recommends using a 5W-30 synthetic motor oil in their 2.5L engines. This oil weight is designed to flow easily at low temperatures during cold starts, while also maintaining viscosity at high operating temperatures. The synthetic formulation provides superior protection against wear, deposits, and breakdown compared to conventional mineral-based oils.


It's important to use an oil that meets the following specifications:



  • API Service Rating: SN or higher

  • ILSAC GF-5 or later

  • Viscosity: 5W-30


Using the correct oil type and weight is crucial for the health and longevity of your Subaru's 2.5L engine. Consult your owner's manual or speak with a Subaru dealer for the most up-to-date oil recommendations.


Oil Change Intervals for Subaru 2.5L Engines


Subaru recommends changing the oil and filter in their 2.5L engines every 6 months or 6,000 miles, whichever comes first. However, some driving conditions may require more frequent oil changes, such as towing, frequent idling, or driving in extreme temperatures.


It's a good idea to check your oil level regularly and top it up as needed between changes. Maintaining proper oil levels is essential for keeping your Subaru's engine running smoothly and preventing premature wear or damage.

Can I use 5W-30 instead of 0W20 in a Subaru Forester?


If you drive a Subaru Forester with a non-turbo engine, it requires 0W-20. If you drive a model with a turbo engine, you'll need 5W-30.



What kind of oil does a Subaru 2.5 take?


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.
