LIQUI MOLY Pro-Line Engine Flush — Cleaner to loosen deposits and contamination in the engine oil system before an oil change. Helps clean passages and the ring area; intended for a short flushing procedure rather than remaining in the new oil.

500 ml treats 5 l of engine oil; measure the required dose from a larger pack. Add to warm used oil, idle the engine for 10–15 minutes, then replace oil and filter. Do not drive during flushing.
