Background of the partnership
Idemitsu Kosan has historically provided lubricants used in Subaru vehicles, and Subaru’s official maintenance oils are frequently associated with Idemitsu formulations.

What oil specifications and branding to expect
Subaru’s official motor oil in many markets is branded as Subaru Genuine Motor Oil and is commonly produced by Idemitsu under license. The oil is designed to meet Subaru’s engine specifications for contemporary models, including viscosity and performance standards. The exact viscosity (for example, 0W-20 or 5W-30) and the spec certifications (such as API/SN or newer equivalents) can vary by engine, model year, and market. Always check the bottle, your owner’s manual, or your Subaru dealer to confirm the correct oil for your vehicle.
- Branding and packaging often show Subaru Genuine Motor Oil with Idemitsu formulations in many markets
- Common viscosities for modern Subaru engines include low-viscosity synthetic oils (e.g., 0W-20), though the exact option depends on model and climate
- Formulations are typically fully synthetic and designed to meet Subaru’s engine requirements
Concluding note: The exact oil supplier and specification can vary by country or model year, so always verify with official Subaru materials or your local dealer before purchase or servicing.
Summary
Idemitsu has played a major role as a supplier of Subaru Genuine Motor Oil in several key markets, reflecting a long-standing partnership between the two companies. However, the arrangement is not universal; some regions may use different suppliers or branding. For the correct oil—brand, viscosity, and specification—consult your owner’s manual or a Subaru authorized service center in your country.
