Full Synthetic While the viscosity rating determines the thickness, the oil’s base stock determines its performance and longevity. Modern engines, particularly the horizontally-opposed Subaru boxer, rely on consistent lubrication to manage the unique forces generated during operation, making the oil choice more than just a maintenance task.

However, it is crucial to adhere to the factory specifications found in the owner’s manual, as using a viscosity that is too high can reduce fuel efficiency and hinder the performance of variable valve timing systems. Selecting the correct Subaru Outback oil type is fundamental to preserving the sophisticated all-weather capability that defines this crossover.
However, even with these systems, it is generally safe to adhere to a schedule of changing the Subaru Outback oil type every 6,000 to 7,500 miles for synthetic oils. The recommended standard for most model years is 0W-20, a multi-grade oil engineered to provide optimal protection year-round.
