I am not suggesting that an oil replace the need to repair a mechanical problem, but I have used this oil and for a short-term solution. It obviously does work. My oil consumption went down. It works well:
Valvoline's MaxLife motor, Specially formulated for higher mileage engines oil is designed specifically for higher mileage engines with over 75,000 miles. Higher mileage engines may perform differently than newer ones - engines lose compression, gaskets become brittle, rings wear and valves do not seal tightly. This contributes to increased oil consumption, reduced gas mileage, decreased engine performance and a more rapid oil breakdown. MaxLife is safe for new and rebuilt engines.
