Wynn’s® Internal Engine Cleaner is ideal for supporting high mileage vehicles by effectively diluting the oil, resulting in better drainage. Despite regular oil changes, the effectiveness of an oil change is limited by the amount of old oil left behind and the contaminants remaining in the oil. This efficient product dissolves sludge and varnish from the crankcase, clearing oil passages.
