Your Subaru is a symbol of adventure, reliability, and a connection to the outdoors. But just like any vehicle, its heart – the engine – needs the right fuel to perform at its best. And that fuel comes in the form of high-quality engine oil. Choosing the right oil can be a daunting task, especially when you consider the vast array of options available. One question that often arises is, “Who makes Subaru engine oil?” Understanding the answer to this question can empower you to make informed decisions about your Subaru’s maintenance and ensure its longevity.

The Subaru Legacy: A History of Partnership
Subaru, known for its innovative engineering and commitment to quality, doesn’t manufacture its own engine oil. Instead, they partner with reputable oil companies to develop and supply oils specifically formulated for their vehicles. This strategic partnership allows Subaru to leverage the expertise of industry leaders while maintaining strict quality control standards.
A Deep Dive into the Partnership
Subaru’s primary engine oil supplier is Idemitsu Kosan Co., Ltd., a Japanese multinational company with a long-standing reputation for producing high-performance lubricants. Idemitsu has been a trusted partner of Subaru for decades, working closely with their engineers to develop oils that meet the unique demands of Subaru’s boxer engines. These engines, known for their horizontally opposed cylinders, require oils with specific viscosity and additive packages to ensure optimal performance and longevity.
Beyond Idemitsu, Subaru may also source engine oil from other reputable manufacturers, depending on regional availability and specific model requirements. However, Idemitsu remains the cornerstone of Subaru’s engine oil supply chain.
Understanding Subaru’s Engine Oil Specifications
Subaru’s commitment to quality extends beyond simply choosing a reputable oil supplier. They also establish stringent specifications for their engine oils, ensuring that they meet the highest performance and protection standards. These specifications are outlined in your owner’s manual and are crucial for maintaining your Subaru’s engine health.
Decoding the Specifications
Subaru engine oil specifications typically include:
- Viscosity Grade: This refers to the oil’s thickness and its ability to flow at different temperatures. Subaru recommends specific viscosity grades for different operating conditions and engine types.
- API Service Category: The American Petroleum Institute (API) sets standards for engine oil performance. Subaru oils meet or exceed these standards, ensuring compatibility with their engines.
- Subaru-Specific Additives: Subaru often incorporates proprietary additives into their engine oils to enhance performance, protection, and longevity. These additives are tailored to the unique characteristics of Subaru engines.
Choosing the Right Engine Oil for Your Subaru
With a clear understanding of Subaru’s engine oil specifications and their partnership with Idemitsu, you can confidently choose the right oil for your vehicle. (See Also: Can You Use Motor Oil to Clean a Gun? The Right Way Always)
Consulting Your Owner’s Manual
Your Subaru’s owner’s manual is your best guide when selecting engine oil. It will specify the recommended viscosity grade, API service category, and any other relevant information. Always refer to your owner’s manual for the most accurate and up-to-date recommendations.
Understanding Viscosity Grades
Viscosity grades are crucial for engine performance. They indicate the oil’s thickness at different temperatures. Subaru recommends specific viscosity grades based on your vehicle’s model year, engine type, and climate.
Common Subaru engine oil viscosity grades include:
- 0W-20: This is a multi-grade oil that flows easily in cold temperatures and maintains viscosity at higher temperatures. It is often recommended for newer Subaru models with fuel-efficient engines.
- 5W-30: This is another popular multi-grade oil that provides a balance of cold-temperature flow and high-temperature viscosity. It is suitable for a wide range of Subaru models.
- 0W-30: This oil offers excellent cold-temperature flow while maintaining adequate viscosity at higher temperatures. It is often recommended for Subaru models operating in colder climates.
The Importance of API Service Category
The API service category indicates the level of performance and protection the oil provides. Subaru engines require oils that meet or exceed specific API standards. These standards cover factors such as detergency, oxidation resistance, and wear protection.
Look for oils with API service categories such as:
- SN Plus: This is the latest API service category for gasoline engines and offers enhanced protection against sludge, deposits, and wear.
- SN: This is a previous API service category that still provides excellent performance and protection for Subaru engines.
Maintaining Your Subaru’s Engine Health
Choosing the right engine oil is just one aspect of maintaining your Subaru’s engine health. Regular oil changes are essential for removing contaminants and ensuring optimal lubrication. (See Also: S9972xl Oil Filter Fits What Vehicle? Compatible Car List)
The Importance of Regular Oil Changes
Engine oil degrades over time due to heat, friction, and exposure to contaminants. Regular oil changes help to remove these contaminants and replenish the oil with fresh lubricant. Subaru recommends oil change intervals based on mileage or time, whichever comes first. Refer to your owner’s manual for specific recommendations.
Beyond Oil Changes: Other Essential Maintenance Practices
In addition to regular oil changes, other essential maintenance practices include:
- Air Filter Replacement: A clean air filter ensures that your engine receives clean air, which is essential for efficient combustion.
- Fuel Filter Replacement: A clean fuel filter prevents contaminants from entering your engine and damaging fuel injectors.
- Spark Plug Replacement: Worn spark plugs can lead to misfires and reduced engine performance.
- Coolant Flush: Coolant helps to regulate engine temperature and prevent overheating. Regular coolant flushes ensure that your cooling system is functioning properly.
Recap: The Key Takeaways
Understanding who makes Subaru engine oil is essential for ensuring your vehicle’s optimal performance and longevity. Subaru partners with reputable oil companies, primarily Idemitsu Kosan Co., Ltd., to develop and supply oils specifically formulated for their engines.
Subaru’s engine oil specifications outline the required viscosity grade, API service category, and any Subaru-specific additives. Always consult your owner’s manual for the most accurate recommendations. Regular oil changes, along with other essential maintenance practices, are crucial for maintaining your Subaru’s engine health.
