Subaru recommends the use of Genuine Subaru Oil, formulated specifically for their boxer engines. While Subaru does not publicly disclose the specific manufacturer of their branded oil, it is widely understood that it is produced by a major oil company to Subaru’s specifications. This specialized formulation is designed to address the unique lubrication needs of horizontally opposed engines, ensuring optimal performance and longevity.
Utilizing a lubricant tailored to the engine’s specific design is crucial for maintaining its health. Proper lubrication minimizes friction and wear within the engine, contributing to improved fuel efficiency and reduced emissions. Furthermore, it helps to protect critical components under demanding operating conditions, potentially extending the engine’s lifespan. Historically, Subaru has emphasized the importance of using their recommended oil, referencing it in owner’s manuals and service recommendations.
