The recommended oil for a 2005 Subaru Impreza is 5w30 with a capacity of 4.4 quarts. It's important to stay on top of regular oil changes, generally every 5,000 to 10,000 miles. Neglecting oil changes can lead to engine issues. Using high-quality oil is crucial for optimal engine performance. Signs that the oil needs attention include a strong burning smell, which should be addressed promptly to avoid potential engine damage. Old or low-quality oil can result in engine failure, indicated by knocking sounds and decreased fuel efficiency.
The 2005 Subaru Impreza WRX STi comes with a 2.5L box-4 turbocharged engine that needs 4.5 quarts of 5W30 synthetic oil. There are two engine options available for the 2005 Impreza WRX: the 2.0L box-4 turbocharged and the 2.5L box-4 non-turbocharged. The 2.0L (turbo) engine requires 4.5 quarts of 5W30 synthetic oil, while the 2.5L (non-turbo) engine needs 4.4 quarts of the same oil type.
