What oil brand is recommended for Subaru?
There isn’t a single brand Subaru requires; you should use a high-quality synthetic motor oil that meets Subaru’s specifications, with 0W-20 being standard for most models.
Official Subaru guidance
Subaru’s owner manuals specify synthetic oil that meets API SN Plus or newer and ILSAC GF-6, with viscosity guidance that most modern Subarus use 0W-20. While Subaru Genuine Motor Oil is available, it is not the only acceptable option as long as the oil meets the required specifications and is changed at the recommended intervals.
What brands fit Subaru's specs?
Before listing brands, note that the key requirement is that the oil is synthetic and meets API SN Plus (or newer) and ILSAC GF-6, with the correct viscosity (typically 0W-20 for many models). The following brands offer 0W-20 full synthetic oils that commonly satisfy those specs:
- Mobil 1 Full Synthetic 0W-20
- Pennzoil Platinum Full Synthetic 0W-20
- Castrol EDGE 0W-20
- Valvoline Advanced Full Synthetic 0W-20
- Motul 8100 0W-20 (or similar 0W-20 synthetic options)
- Amsoil Signature Series 0W-20
- Subaru Genuine Motor Oil 0W-20 (OEM option)
Always check the bottle to confirm it meets API SN Plus and ILSAC GF-6 and that the viscosity shown is 0W-20 (or the grade specified for your model).
Viscosity guidance by model and climate
For most modern Subaru engines, 0W-20 synthetic is recommended to balance cold-weather performance with fuel economy and protection. Some older models or specific climates may call for 5W-30, so always verify the exact specification in your owner's manual for your year and engine code.
Turbocharged engines and OEM guidance
Turbocharged Subaru engines (such as certain WRX/STI variants) may have nuanced oil recommendations depending on the year and engine design. In those cases, follow the manual or dealer guidance for the precise viscosity and spec beyond the general rule of 0W-20.
Dealer vs. DIY and warranty considerations
Subaru warranties generally cover oil changes when they are performed with the correct oil type and intervals, whether at a dealership or a qualified independent shop. Keeping receipts and a record of the oil grade and change date helps with documentation.
Maintenance intervals and service tips
Oil-change intervals depend on model year, driving conditions, and oil type. With synthetic oil meeting Subaru specs, many owners follow intervals around 6,000–7,500 miles (or as recommended in the manual); harsher driving conditions or severe use may require more frequent changes. Always follow the exact interval stated in your owner’s manual and service reminders.
Summary
Bottom line: Subaru does not require a single brand. Use a reputable synthetic oil that meets API SN Plus or newer and ILSAC GF-6, in the viscosity specified for your model (commonly 0W-20). Brands like Mobil 1, Pennzoil, Castrol, Valvoline, Motul, Amsoil, or Subaru Genuine Oil are all suitable—as long as they meet the manufacturer’s specifications and are changed at the recommended intervals.
