Ensuring Optimal Subaru Outback Engine Protection with Quality Oil
Modern Subarus are engineered for tight internal tolerances, which means they require a high-quality synthetic oil that maintains its protective film under stress. Subaru's vehicles require oils that meet the Subaru Global Specification (SGP) to ensure the catalytic converter and emissions systems are protected.
Using a 10W-30 or thicker oil, a common practice in older vehicles, can actually harm your modern Outback by causing poor fuel economy and inadequate lubrication during cold starts. Choosing an oil with superior high-temperature high-shear (HTHS) stability will protect the engine during summer driving or when towing a trailer up a steep grade.
