Does Subaru have special oil?
Subaru does not use a proprietary, one-of-a-kind oil that only Subaru markets. The company specifies the correct viscosity and engine-oil standards for each model, and Subaru Genuine Motor Oil is offered as a formulation designed to meet those specifications. In practice, many high-quality aftermarket oils that meet Subaru’s required specs can be used successfully as long as they adhere to the prescribed viscosity and approvals.
Understanding Subaru’s oil requirements
Subaru engines are designed to run on high-quality synthetic oils that meet specific industry standards and the automaker’s own recommendations. The key factors are viscosity, the oil’s synthetic composition, and the performance certifications on the label. Here is a quick guide to the main requirements you should check when selecting oil.
Before the list, note that picking the right oil isn’t just about a brand name; it’s about meeting Subaru’s specifications and your driving conditions.
- Viscosity: Most modern Subaru engines use 0W-20 full synthetic oil. Some turbocharged models or extreme climates may call for different viscosities (for example, 5W-30). Always confirm with your owner's manual for the exact grade.
- Oil type: Subaru generally recommends synthetic oil for newer engines to ensure adequate protection and performance. Conventional oils are typically not recommended for these engines.
- Industry specifications: Look for oils that meet API SN or newer and ILSAC GF-5 or GF-6 specifications. These certifications indicate compatibility with modern engines and emission systems.
- Subaru’s own certification: Subaru Genuine Motor Oil is formulated to meet Subaru’s requirements, and Subaru dealerships carry it for convenience.
- Oil-change intervals: With synthetic oil, Subaru’s normal-service intervals are typically longer than conventional oil, but severe-driving conditions (short trips, extreme temperatures) may require more frequent changes. Always follow the manual’s guidance.
In summary, the oil you choose should match the vehicle’s viscosity recommendation and meet API/SNS/ILSAC specs; Subaru Genuine Oil is one way to ensure compliance, but equivalent aftermarket oils can also satisfy Subaru’s requirements when labeled correctly.
Subaru Genuine Oil vs. aftermarket options
The market offers two broad approaches to satisfying Subaru’s oil needs: using Subaru Genuine Motor Oil or selecting a reputable aftermarket oil that meets the same specifications. Here are the main considerations.
- Subaru Genuine Motor Oil: This is the official Subaru-branded oil (commonly 0W-20 full synthetic) designed to meet Subaru’s engine requirements. It’s widely stocked at Subaru dealers and parts retailers and is often favored for warranty purposes and straightforward service checks.
- aftermarket oils that meet Subaru specs: Many well-known brands offer 0W-20 full synthetic oils that meet API SN or newer and ILSAC GF-5/GF-6, with clear labeling indicating compliance with Subaru’s requirements. When choosing aftermarket oil, verify the viscosity, the API/ILSAC ratings, and any Subaru-specific notes on the bottle.
- Climate and engine specifics: Some engines or environments may require different grades (for instance, certain turbocharged or high-temperature applications). Always follow the model’s manual, and consult a qualified technician if you’re unsure.
Concluding, Subaru Genuine Oil is a convenient, fully compatible option, but high-quality aftermarket oils that carry the correct viscosity and approvals are acceptable and common alternatives.
How to choose oil and maintain your Subaru
To keep your Subaru running smoothly, follow these practical steps to select and maintain the right oil.
- Check the owner’s manual for the exact viscosity and specification required for your model and engine.
- Choose a high-quality full synthetic oil that meets API SN (or newer) and ILSAC GF-5/GF-6, and matches the recommended viscosity (usually 0W-20 for modern engines).
- Decide between Subaru Genuine Motor Oil and a reputable aftermarket oil that carries the same specs. Confirm the bottle lists the required viscosity and approvals.
- Adhere to the recommended oil-change interval for normal and severe service. Synthetic oils typically allow longer intervals (often around 7,500 miles/12,000 km) under normal use; shorter intervals apply to severe conditions.
- Have the oil change performed with the correct fill amount and a properly installed oil filter, using a qualified technician if you’re not confident doing it yourself.
Concluding, using the right oil and following the service schedule helps protect your engine and supports warranty terms.
Summary
Subaru does not rely on a mysterious, exclusive oil; instead, it prescribes a viscosity and standards that most high-quality synthetic oils can meet. Subaru Genuine Motor Oil is available as an OEM option and is designed to meet Subaru’s requirements, but aftermarket oils that meet the same viscosity and certification standards are acceptable. Always consult your owner's manual for the exact oil grade and change intervals, and choose an oil that complies with API SN or newer and ILSAC GF-5/GF-6.
