the 2.7L chrysler engines were known to blow major oil when they hit higher mileage. My intrepid was no different. It left a nice puff of blue smoke at every stop light starting at about 120,000 miles. At my last oil change, I threw in a bottle of Heavy Duty Oil Stabilizer and have not lost a drop of oil in the 1500 miles since the change. It sure beats having to get the exhaust seals replaced. Thanks.
