Understanding the 2019 Subaru Forester oil capacity is essential for proper vehicle maintenance and ensuring the longevity of its horizontally-opposed engine. This specific model year, part of the fourth generation, utilizes a sophisticated design that requires the correct amount of lubricant to function optimally. Installing the wrong quantity can lead to poor lubrication or, conversely, overfilling can cause pressure issues and potential seal damage.
Factory Specifications for 2019 Models
For the 2019 model year, Subaru provides specific guidelines regarding the 2019 subaru forester oil capacity, which varies slightly depending on the trim level and whether the vehicle is equipped with the standard turbocharged engine. The general consensus from manufacturer specifications is that the system holds approximately 4.9 to 5.6 quarts of oil. This range accounts for the standard filter and the oil pan design.
Standard Non-Turbo Capacity
The base models and those equipped with the naturally aspirated 2.5-liter engine typically have a slightly smaller oil capacity. When performing a standard oil change on these variants, the recommended amount is generally around 4.9 quarts. This ensures the oil pump is sufficiently lubricated without overfilling the drain pan or the oil filter cavity.
Turbocharged Engine Requirements
For models equipped with the 2.0-liter turbocharged boxer engine, the oil capacity increases due to the added stress and cooling requirements of the forced induction system. Owners of the turbocharged variants should expect to use closer to 5.5 or 5.6 quarts during a complete oil change. The extra volume is necessary to maintain proper oil pressure and temperature management within the turbo system.
The Importance of the Oil Filter
When calculating the total 2019 subaru forester oil capacity, one must factor in the oil filter's internal volume. Subaru uses a specific filter element that holds a small amount of oil. If you are changing the filter yourself, simply draining the oil pan is not enough; the new filter will contain roughly 3 to 4 ounces of oil that is part of the total capacity. Always fill the engine to the correct level after installing the new filter.
Type of Lubricant Required
Beyond just the capacity, the 2019 Forester requires a specific type of lubricant to meet Subaru's rigorous standards. The manufacturer recommends using a synthetic oil that meets the requirements of Subaru's specification "STI" version 040. Look for oils labeled as meeting this standard, as this ensures the correct viscosity and additive package for the turbocharged units. Using a non-approved oil can void the warranty and reduce engine life.
Step-by-Step Refill Procedure
To accurately achieve the proper 2019 subaru forester oil capacity, follow these steps carefully. First, ensure the engine is warm to allow old oil to drain completely. Position the vehicle on a level surface and remove the drain plug. Once the oil has finished draining, replace the filter and secure the drain plug. Begin pouring the new oil slowly, checking the dipstick frequently. Stop filling once the dipstick reads just below the "Full" hash marks.
Consequences of Incorrect Levels
Deviating from the recommended oil levels for the 2019 Forester can have serious consequences. Underfilling the crankcase can lead to insufficient lubrication, causing increased friction and potentially catastrophic engine failure. Overfilling, on the other hand, can cause the crankshaft to whip the oil into a froth, which reduces lubrication effectiveness and can lead to oil leaks or damage to the seals.
