Liqui Moly Pro-Line Engine Flush 1 L, Single

Liqui Moly Pro-Line engine flush 1 litre single can

Engine flush treatment for petrol and diesel engines, supplied as a 1 litre single can for oil-system cleaning before an oil change.

This engine flush is designed to clean the oil system before an oil change. It is listed for petrol and diesel engines and is used by adding it to the engine oil at running temperature, then allowing the engine to idle before draining the oil and changing the filter.

What it is used for

The product is intended to help remove deposits from areas such as lubrication holes, oil screens and the piston ring zone. The listing also states that it can reduce engine noise and oil consumption, while supporting compression and overall reliability.

How it is applied

• Add the flush to warm engine oil before the oil is changed.
• Let the engine idle for around 10 to 15 minutes, depending on how dirty the system is.
• Drain the oil afterwards and replace the filter.

Points to check before buying

• One 500 ml can is stated as sufficient for up to 5 litres of oil.
• It is compatible with all commercially available engine oils.
• The listing says it is not suitable for motorbikes with wet clutches.
• The selected size for this product is 1 litre, supplied as a single pack.

For shoppers maintaining a petrol or diesel engine, this is a straightforward pre-service flush rather than a permanent additive. The key thing is to follow the label guidance and make sure it suits your vehicle and oil capacity before use.
