Product Information
Full details
Liqui Moly Motorbike Engine Flush (1657) is a specialized cleaning additive designed for motorcycle enthusiasts and mechanics looking to maintain engine longevity and performance by removing sludge, lacquer, and carbon deposits. It is ideal for owners of 4-stroke motorcycles who want to ensure their fresh oil performs optimally after an oil change, though it is important to note that it must be added shortly before a scheduled oil change rather than being left in the engine during regular operation.

Extended Product Information
FAQs
Can I leave this product in the oil for a longer period?
No, you must drain the oil and replace the filter within 10 minutes of adding the flush while the engine is idling.
Does this product work on 2-stroke engines?
No, this specific product (1657) is engineered for 4-stroke gasoline engines only.
Will this harm my engine seals?
The formula is designed to be neutral toward common sealing materials, so it will not damage gaskets or seals.
What if my oil capacity is more than 4.5 liters?
You should use an additional bottle for larger oil capacities to ensure the cleaning concentration is sufficient.
Is it safe for a bike with a catalytic converter?
Yes, this product is fully compatible with catalytic converters.
Do I need to change the oil filter too?
Yes, always change the oil filter during the oil change process to remove the contaminants caught during the flush.
Troubleshooting
Engine oil is extremely dark or thick after 10 minutes
This is normal as the product has successfully lifted sludge and deposits; proceed immediately with the oil and filter change to remove these suspended contaminants.
Not sure if it is safe for my specific motorcycle clutch

Setup, Compatibility & Care
This product is compatible with all commercially available 4-stroke motorcycle engine oils. It is specifically designed for 4-stroke gasoline engines.

Always dispose of the used oil and the cleaning mixture in accordance with local environmental regulations.
