Understanding the 2017 Subaru Impreza oil capacity is essential for proper vehicle maintenance and longevity. This specific model year, part of the seventh generation, requires precise oil volumes to ensure optimal engine performance and protection. Using the correct amount of oil prevents engine damage and maintains the efficiency of the horizontally-opposed "Boxer" engine.
2017 Impreza Oil Specifications by Trim
The oil capacity for the 2017 Subaru Impreza varies slightly depending on the specific trim level and engine configuration. While most models share the same 2.0-liter four-cylinder engine, the exact fill volume can differ between the base model, Premium, Limited, and Touring trims. Always refer to your specific vehicle's manual for the most accurate measurement, as these figures serve as a general guideline.
Standard Capacity for Most Trims
For the majority of 2017 Impreza trims equipped with the standard FB20 engine, the total oil capacity is approximately 4.2 quarts. This includes the oil filter and accounts for the oil pan's design. When performing an oil change, it is recommended to add oil incrementally and check the dipstick frequently to avoid overfilling, which can lead to increased pressure and potential seal damage.
Checking and Adding Oil Correctly
To accurately measure the oil capacity, you must check the level with the engine off and the vehicle on a level surface. Remove the dipstick, wipe it clean, reinsert it fully, and then remove it again to get an exact reading. The oil should be between the "MIN" and "MAX" lines. If the level is near the "MIN" line, you should add oil until it reaches the "MAX" line, noting the total amount added.
Ensure the engine is cool before opening the oil filler cap to prevent burns.
Use the manufacturer-recommended oil viscosity, typically 5W-30 for most climates.
Replace the oil filter with every oil change to trap contaminants effectively.
Dispose of old oil and filters at a certified recycling center.
A funnel is highly recommended to prevent spills and ensure a clean pour.
Why Capacity Matters for the Boxer Engine
The Subaru Boxer engine's unique flat design means oil pools differently than in a conventional inline engine. Because of this layout, getting the exact oil capacity right is vital for ensuring all moving parts, such as the horizontally-opposed pistons and crankshaft, receive adequate lubrication. Insufficient oil can cause premature wear, while overfilling can cause oil to enter the combustion chamber, leading to smoke and reduced efficiency.
OEM vs. Aftermarket Filters
The difference between using an Original Equipment Manufacturer (OEM) filter and an aftermarket filter can affect the total oil capacity. Aftermarket filters sometimes have a slightly larger or smaller internal volume compared to the Subaru OEM part. Consequently, when switching filter brands, you might need to adjust the total amount of oil added by a small margin, usually a few ounces, to reach the correct operating level.
Final Recommendations for Maintenance
For the 2017 Subaru Impreza, sticking to the recommended maintenance schedule is the best way to protect your investment. While the total oil capacity is a key detail, also pay attention to the oil change interval and the type of oil used. Regular checks and timely changes will ensure the engine runs smoothly for high mileage, preserving the vehicle's value and reliability over time.
