Volvo S60 oil burning issue requiring 1 quart monthly, potential piston and ring replacement on Volvo S60

Some Volvo S60 owners report experiencing excessive oil consumption, requiring up to 1 quart of oil per month due to potential piston and ring issues. This problem can result in soot covering the back of the vehicle and may not always present with visible leaks or exhaust smoke. Owners have noted that if oil consumption exceeds normal levels, Volvo may assist with parts and labor costs, particularly for piston and ring replacements. Additionally, the burned oil can contaminate the combustion chamber, leading to the need for maintenance such as fuel system cleaners. There have also been reports of certain engine models facing oil consumption problems, which have resulted in class action lawsuits and potential recalls. It is crucial for owners experiencing significant oil burning to address the issue promptly to avoid further complications and potential engine damage.
