★ Top Answer
The 2004 Subaru Forester requires 2.5 liters of 4-cylinder engine and uses 5W-30 Synthetic Motor Oil. When filling the vehicle, it should be filled with 4.2 quarts along with a filter. The numbers 5, W, and 30 in the oil specification indicate the thickness or viscosity at start-up, winter classification, and operating speeds, respectively. Oil plays a crucial role in maintaining engine cleanliness and lubrication to reduce friction between moving parts. It is important to change the oil regularly as it does not last indefinitely. For the Forester, it is recommended to change the oil every 30,000 miles, along with the filter. The oil change process is relatively quick, typically taking between 5 to 15 minutes to complete.

Both the 2.5L non-turbo and turbo versions of the engine in the 2004 Subaru Forester require 4.2 quarts of oil. Both use synthetic oil of the same viscosity, but Subaru recommends various viscosities depending on driving conditions and weather. For temperatures above -4 degrees Fahrenheit, it is preferred to use 5W30, but 10W30 or 10W40 can also be used. For temperatures above 95 degrees Fahrenheit and/or heavy usage like towing, it is recommended to use 30 weight, 40 weight, 10W50, 20W40, or 20W50. It is advised to consult your local dealership to determine the most suitable oil based on your location.
