What brand engine oil does Subaru use?
Subaru does not require a single brand of engine oil; it specifies the oil grade and performance standards, and most models use 0W-20 synthetic oil. Any reputable brand that meets those specs is acceptable.
Understanding Subaru’s oil specifications
In Subaru’s manuals, the emphasis is on viscosity and standards rather than a particular manufacturer. For most contemporary Subaru engines in North America, the recommended viscosity is 0W-20 full synthetic, with alternatives allowed only if specified by your climate or model. Oils must meet API specifications and ILSAC quality standards (API SN or newer, ILSAC GF-5 or GF-6). Always consult your owner's manual for your exact model and year.
Here are the typical viscosity guidelines and compatibility notes you should follow:
- 0W-20 synthetic oil is the default recommendation for most current Subaru engines in typical climates.
- 5W-30 synthetic oil may be used in some climates or if 0W-20 is not readily available, per the owner's manual.
- Always verify the oil meets API SN or newer and ILSAC GF-5 or GF-6 specifications.
In short, the key is to match the oil to Subaru's specification rather than chasing a single brand.
Brands that commonly meet Subaru specs
Many mainstream oil brands offer 0W-20 full synthetic that meets Subaru's required standards. You can choose among reputable brands provided the oil is labeled 0W-20 Full Synthetic and carries API SN/SP and ILSAC GF-5/GF-6 marks, and is suitable for Subaru engines.
Examples of brands that offer 0W-20 synthetic oils suitable for Subaru include:
- Mobil 1
- Pennzoil
- Castrol
- Valvoline
- Royal Purple
- Motul
- Subaru Genuine Motor Oil
Always check the bottle label to confirm viscosity and specifications; if in doubt, ask your Subaru dealer or service advisor.
How to choose and verify the right oil
To ensure you’re using the correct oil for your Subaru, use these verification steps before pouring anything into the engine:
- Confirm the viscosity on the oil label matches your vehicle’s manual (most current Subaru models: 0W-20).
- Look for API SN (or newer) and ILSAC GF-5 or GF-6 performance standards on the packaging.
- Ensure the oil is full synthetic rather than conventional, unless your manual allows conventional in older models.
- Follow the service interval recommended in your owner's manual or by your dealer.
By verifying these details, you ensure compatibility and maximum engine protection for your Subaru.
Subaru Genuine Oil vs. other brands
Subaru offers its own branded engine oil formulated to meet Subaru engine requirements, but other reputable brands that meet the same viscosity and performance standards are also suitable. The governing factors are the viscosity, the API/ILSAC rating, and whether the oil is synthetic, not the manufacturer label alone. If you prefer peace of mind, Subaru Genuine Oil is a convenient option that is specifically designed for Subaru engines.
Summary
Subaru does not mandate a single oil brand. The essential requirements are the correct viscosity (primarily 0W-20 for most current models), full synthetic formulation, and compatibility with API SN/SP and ILSAC GF-5 or GF-6 standards. You can use any reputable brand that meets these specifications, including Subaru Genuine Oil, as long as the label confirms the proper viscosity and standards. Always consult your owner's manual for model-specific guidance and climate considerations.
