Understanding the precise 2016 Subaru Impreza oil capacity is fundamental for ensuring the longevity and peak performance of your specific model. Whether you drive the standard sedan, the elevated Crosstrek variant, or the sport-focused WRX, the heart of the engine relies on the correct volume of lubricant to function efficiently. This detailed guide breaks down the specifications for 2016 models, helping you avoid the common pitfalls of under-filling or over-filling during maintenance.
2016 Subaru Impreza Oil Specifications by Trim
The year 2016 marked a significant update for the Impreza line, featuring the new FA20DIT horizontally-opposed engine. While the displacement remained at 2.0 liters, the oil capacity varied slightly depending on the specific trim and drivetrain configuration. It is crucial to identify your exact model to ensure accuracy during your next oil change.
Base Models: L, LS, and Premium
For the standard base trims including the L, LS, and Premium, the oil capacity is generally consistent across the board. These models utilize the naturally aspirated-like turbocharged FA20DIT engine without the complexity of all-wheel-drive systems that require additional fluid. The recommended volume for these configurations is typically 4.4 quarts, which is approximately 4.2 liters.
WRX and Limited Editions
The performance-oriented WRX and higher trims like the Limited often share the same base engine but may include features that influence maintenance. For the 2016 WRX and Limited trims, the oil capacity remains the same as the base models. You will need approximately 4.4 quarts (4.2 liters) of the correct viscosity to maintain optimal lubrication and cooling under varying driving conditions.
Crosstrek and Sport Variants
The Subaru Impreza Crosstrek, with its raised suspension and all-weather capability, and the Sport package models utilize the same 2.0-liter turbocharged engine. Consequently, the 2016 Crosstrek and Sport variants also adhere to the standard oil capacity. Owners should plan to add 4.4 quarts (4.2 liters) of oil to achieve the proper fill level for their specific chassis.
Why Capacity Matters
Filling your engine with the correct amount of oil is not just about meeting a specification; it is about ensuring the longevity of critical components. An under-filled engine risks inadequate lubrication, leading to increased friction and potential overheating. Conversely, an over-filled engine can cause oil to become aerated, reducing its lubricating properties and potentially leading to seal damage. Checking Your Dipstick Even when following the 4.4-quart guideline, always verify the oil level using the dipstick after an oil change. Park your 2016 Impreza on a level surface, allow the engine to cool, and wait a few minutes for the oil to settle in the oil pan. Pull the dipstick, wipe it clean, reinsert it fully, and then pull it out again to get an accurate reading. The oil level should be between the "Min" and "Max" lines.
Checking Your Dipstick
Recommended Oil Type
To complement the correct capacity, selecting the right oil viscosity is equally important for the FA20DIT engine. Subaru recommends using a synthetic oil with a viscosity of 5W-30 for most driving conditions. This grade provides excellent protection during cold starts and maintains stability under high temperatures, ensuring the turbocharged engine operates smoothly year-round.
