LIQUI MOLY 2037 Pro-Line Engine Flush is a professional-grade engine oil system cleaner designed to remove deposits and contaminants from inside compatible 4-stroke gasoline and diesel engines before an oil change.
The formula helps clean oil passages, bearings, piston ring areas, and other internal lubricated components so fresh engine oil can perform more effectively after service. It is suitable for engines with or without turbochargers, catalytic converters, and gasoline or diesel particulate filters.
