Understanding the 2017 Subaru Outback oil capacity is essential for any owner or prospective buyer looking to maintain this capable crossover effectively. This specific model year, part of the fourth generation, was engineered with a focus on durability and all-weather capability, and proper lubrication is central to that design. The figures discussed here are not arbitrary; they are the result of extensive testing by Subaru engineers to ensure optimal engine protection and performance under various driving conditions.
Factory Specifications for the 2017 Model Year
For the 2017 Subaru Outback, the factory oil capacity varies slightly depending on the specific engine option chosen by the buyer. The standard and most common configuration was the 2.5-liter horizontally-opposing Subaru BOXER engine. With this powertrain, the total oil capacity is approximately 4.8 to 5.3 quarts. This range accounts for the oil filter itself and ensures the lubrication system is filled to the correct level for peak efficiency.
Engine Option Variations
While the 2.5-liter engine was the workhorse for the majority of the lineup, Subaru also offered a more powerful 3.6-liter six-cylinder engine in the premium Touring models. This larger displacement powerplant required a corresponding increase in lubrication, pushing the total oil capacity to a range of approximately 5.5 to 6.0 quarts. It is critical to identify which engine is installed in your specific vehicle, as overfilling or underfilling can lead to significant long-term damage.
The Importance of Using the Correct Oil
Capacity is only one part of the equation; the specification of the oil used is equally important for the longevity of the 2017 Outback. Subaru strongly recommends using a synthetic oil that meets the requirements of the Subaru Oil Standard. Look for oils labeled as meeting Subaru STI specification 220 or later, which ensures the proper additives and viscosity are present. This is particularly important for the BOXER engine, which relies on a specific oil flow pattern for optimal lubrication of the horizontally-moving pistons.
Always refer to the owner’s manual for the exact oil weight, such as 5W-30 or 0W-20, as determined by the factory.
Using a high-quality synthetic oil can help maintain fuel efficiency and protect the engine in extreme climates.
The wrong viscosity can hinder performance and potentially void warranties or cause premature wear.
Maintenance Procedures and Best Practices
When performing an oil change on a 2017 Outback, accuracy is key to determining the final capacity. After draining the old oil and replacing the filter, the procedure involves adding the new oil through the fill port under the hood. It is recommended to add the oil incrementally, checking the level with the dipstick frequently. The engine should be running, and the vehicle should be on a level surface to get an accurate reading and prevent overfilling, which can cause increased pressure and seal failure.
Checking Your Specific Vehicle's Capacity
Because trim levels and model year sub-variations exist, the most reliable way to confirm the oil capacity for your specific 2017 Subaru Outback is to consult the vehicle documentation. The owner’s manual contains a detailed maintenance section that lists the exact type and amount of fluid required. Alternatively, the original window sticker or the information placard located in the driver’s door jamb will list the factory fill amount. This ensures you are following the precise specifications for the build date of your automobile.
