What is the best oil for a Subaru?
Most Subarus run best on a fully synthetic 0W-20 motor oil that meets Subaru specifications, a standard recommendation for the majority of modern models as of 2024–2025. Always verify the exact viscosity and certification in your owner's manual or with a Subaru dealer.
Subaru's guidance varies by model year, engine type, climate, and driving conditions. While 0W-20 is the default for many engines, some older designs or very hot climates may call for a different viscosity, and turbocharged variants can have distinct requirements. Use oil that meets API SN Plus or ILSAC GF-6 and Subaru's specifications, and follow the recommended change intervals in your manual.
Key oil recommendations for Subaru models
The following list summarizes the standard guidance you’ll see in Subaru's manuals and service advisories.
- Best default oil: fully synthetic 0W-20 that meets Subaru specifications and API SN Plus/ILSAC GF-6.
- When to consider 5W-30: if your manual specifies it for very hot climates, heavy towing, or certain engine variants; only use if explicitly recommended for your model.
- Quality and packaging: choose a top-tier synthetic brand, ideally Subaru Genuine Motor Oil or an equivalent that meets the required spec.
- Oil change interval: follow Subaru’s schedule, which varies with driving conditions; severe driving can require more frequent changes.
In practice, sticking with 0W-20 synthetic oil is the safe default for most Subarus, with adjustments only when your manual calls for it.
Model-specific notes
Non-turbo 2.5L and 2.0L engines
For most 2012-and-newer non-turbo Subarus, 0W-20 synthetic is the standard and recommended choice. Always verify the exact grade in your owner's manual.
Turbocharged and high-performance models (WRX/STI)
Turbo and performance variants can have different viscosity recommendations depending on year and climate; consult your manual or dealer to confirm whether 0W-20, 5W-30, or another grade is advised.
Hybrid models
Subaru's hybrid models typically use the same 0W-20 synthetic guidance, but always check the manual for any exceptions.
Note: The guidance above reflects current practice as of 2024–2025 and can vary by region. Always rely on your vehicle’s owner’s manual or an authorized Subaru service center for the exact specification for your model and location.
Summary
For most Subaru owners, the best oil is a fully synthetic 0W-20 that meets Subaru’s specifications and API/ILSAC standards, paired with regular changes per the manual. Use 5W-30 only if your manual or dealer explicitly allows it for your engine, climate, and driving style. Always confirm the precise viscosity and certification in the owner's manual or with a Subaru service advisor.
