Maintaining the longevity and performance of your 2016 Subaru Impreza starts with one of the most fundamental procedures in automotive care: the oil change. This specific model, known for its symmetrical all-wheel drive and boxer engine, has specific requirements that make using the correct oil and filter non-negotiable. Getting this service right protects your investment and ensures the turbocharged efficiency (if equipped) or the naturally aspirated reliability you expect from Subaru continues for miles to come.
Why the 2016 Impreza Needs Specific Oil
The heart of the 2016 Impreza is a precision machine that demands the right lubrication. Unlike standard four-cylinder engines, the Subaru boxer lies flat, which allows for a lower center of gravity but creates unique oil drainage characteristics. Using the wrong weight or grade can lead to inadequate lubrication during startup, increased wear on the moving parts, and a reduction in the engine's ability to manage heat. This is especially true for models equipped the turbocharged engine, which operates at higher temperatures and requires oil that can maintain its viscosity under stress.
Recommended Oil Specifications
For the vast majority of 2016 Impreza models, manufacturers recommend a 5W-30 viscosity grade. This specific rating provides the ideal balance between fluidity in cold weather, which ensures easy starts, and stability in hot conditions, which maintains a proper seal around the pistons. Always verify this specification in your owner’s manual, as models with the turbocharged "XT" engine almost always require this premium synthetic blend to meet the demands of the turbocharger.
Viscosity: 5W-30 (0W-20 is also acceptable for some trims, check your manual)
Type: Full synthetic is highly recommended for optimal performance and engine protection
Capacity: Typically between 4.4 to 4.7 quarts, depending on the specific engine configuration
Filter: A genuine Subaru oil filter or a high-quality aftermarket brand designed for the flat-four layout
The Oil Change Procedure Simplified
While many owners opt for a professional service, understanding the process empowers you to maintain your vehicle confidently. The procedure involves draining the old, contaminated oil, replacing the filter to capture future debris, and refilling with fresh oil to the precise level. Because the 2016 Impreza has a low clearance exhaust system, you must ensure the vehicle is lifted safely if performing this task at home. The process usually involves warming up the engine first, which suspends the dirt particles in the oil, allowing for a more complete drain.
Step-by-Step Highlights
To execute a proper change, you will need a socket set that fits the drain plug (usually 15mm), an oil filter wrench, a drain pan, and new crush washers for the plug. After positioning the car safely, remove the drain plug and allow the oil to flow completely into the pan. While the oil drains, remove the old oil filter; be prepared for some spillage. Before installing the new filter, apply a small amount of new oil to the gasket. This ensures a proper seal without over-tightening, which can make future changes difficult.
