What is the life expectancy of piston rings?
How Long Do Piston Rings Last? Piston rings typically last between 100,000 and 150,000 miles. While complications and wear can reduce this life span, a well-maintained piston ring can last as long as the engine. On average, most car engines are designed to last between 150,000 to 200,000 miles. However, with the right care, many engines can last much longer, even up to 300,000 miles or more. In fact, there are numerous stories of vehicles reaching the 500,000-mile mark with their original engine still intact.
