Is Subaru oil made by Idemitsu?
Yes. Subaru Genuine Motor Oil is commonly produced under contract by Idemitsu in many markets, reflecting a long-running partnership. As of 2024–2025, Idemitsu remains a primary supplier for Subaru OEM oil in several regions, though branding and exact suppliers can vary by market and model year.
Background of the Subaru-Idemitsu partnership
Subaru has long relied on Idemitsu to supply lubricants that meet its engine specifications. This collaboration aims to ensure compatibility with Subaru engines across various regions and models, aligning with Subaru’s service standards and warranty requirements. While Idemitsu is a major player in Subaru’s oil supply, regional arrangements can shift over time and may involve alternative suppliers in some markets.
Key details about how the arrangement typically works:
- Subaru specifies the required oil grades, viscosity, and additive package for each market and engine family.
- Idemitsu manufactures the oil to those Subaru specs, sometimes sold as Subaru Genuine Motor Oil and other times as an Idemitsu-branded product that meets Subaru's specifications.
- Branding and supplier (Subaru vs. Idemitsu) can differ by region and release cycle, so bottle labeling should be checked for the exact origin.
Conclusion: The relationship generally means Idemitsu is a major OEM oil supplier for Subaru in many regions, though the exact branding or supplier can vary by year and market.
Regional variations and current status
Oil supply arrangements can shift with contracts and regional distribution. The United States, Canada, Europe, and Asia-Pacific all have different supply patterns. Always check the bottle label and the owner's manual to confirm the exact supplier and specification for your vehicle.
Typical regional patterns:
- United States and Canada: Subaru Genuine Motor Oil commonly aligns with Idemitsu supply; many bottles may carry Idemitsu branding or Subaru Genuine labeling that designates compliance with Subaru’s specifications.
- Europe and some Asia-Pacific markets: Idemitsu or other approved OEM oil suppliers may produce oil that meets Subaru specs; availability varies by country and dealer network.
- Newer partnerships and re-labelling: Some markets may offer lubricants that are produced by Idemitsu but sold under different retailers or house brands while still meeting Subaru's technical specs.
Conclusion: Idemitsu plays a leading role in Subaru's OEM oil supply in many regions, but always verify the exact label on your bottle to ensure it meets your model's requirements.
How to verify which oil to use
To be sure you’re using oil that meets Subaru’s specifications, consult the owner's manual and check the product label. If you’re unsure, contact a local Subaru dealer or service center for guidance on the correct viscosity and specification for your vehicle and region.
What to look for on the bottle
Look for Subaru Genuine Motor Oil branding or Idemitsu branding, along with the recommended viscosity (for example, 0W-20 or 5W-30) and any Subaru specification codes listed on the label.
When in doubt, ask your dealer
Your Subaru dealer can confirm whether a given oil is appropriate for your engine and warranty considerations, and can advise on current regional supply arrangements.
Summary
Subaru's oil supply relationship with Idemitsu is longstanding and widely observed in many markets, making Idemitsu a common source of Subaru OEM lubricants. However, regional variations exist, and always verify the exact supplier and specification for your vehicle by checking the bottle and consulting official resources.
