Volvo S60 high oil consumption issue possibly normal for 2.5t engine on Volvo S60

Some Volvo S60 owners report experiencing high oil consumption issues, particularly with the 2.5T engine, which is often linked to a design flaw in the piston rings that can become clogged with carbon deposits. This problem can prevent the oil control ring from effectively scraping oil back into the crankcase, leading to increased oil consumption. Reports indicate that certain models, such as the 2012 Volvo S60, have faced significant excessive oil consumption problems, with repair costs averaging around $4,750 at approximately 79,900 miles. Volvo has acknowledged this issue and has offered oil consumption tests and extended warranties to affected drivers. Owners suspecting high oil consumption are advised to have their dealer conduct these tests to evaluate oil levels, as Volvo may assist with parts and labor costs for necessary repairs based on the results. Additionally, it is crucial for owners to use the correct engine oil, specifically fully synthetic engine oil of at least 0W-20 C6 (API SP), to ensure optimal engine performance and protection. Addressing high oil consumption promptly is essential to prevent long-term engine damage or performance issues.
