LIQUI MOLY Engine Flush Plus – 300ml

LIQUI MOLY Engine Flush Plus is a powerful engine cleaning additive designed to remove harmful deposits, sludge and contaminants from the internal engine oil system before an oil change.

These are potential applications based on the product's general petrol and diesel engine suitability, not Porsche-specific approvals. Check vehicle requirements and engine oil capacity before use.

Its cleaning formula dissolves and suspends oil-soluble and oil-insoluble deposits, allowing them to be drained away with the old engine oil. This helps restore cleanliness, reduce wear and support efficient engine operation.

Not applicable to fully electric Porsche Taycan or Macan Electric powertrains.

What Does It Do?

Engine Flush Plus cleans the internal engine oil circuit by loosening and suspending accumulated deposits.

These contaminants are then removed when the old engine oil and filter are replaced.

Why Is It Important?

Over time, engine oil can accumulate sludge, varnish and other deposits caused by heat, combustion by-products and normal engine operation.

Excessive contamination may restrict oil circulation and increase engine wear.

When Should It Be Used?

Use immediately before an engine oil change when additional internal cleaning is required.

It may be useful during routine servicing, particularly where deposits or contamination are suspected. It is not a substitute for repairing mechanical faults or blocked oil passages.

Application & Dosage

• Bring the engine oil to normal operating temperature.
• Add Engine Flush Plus to the existing engine oil.
