Product Information

Full details

Liqui Moly Motorbike Engine Flush is designed for motorcycle enthusiasts and mechanics looking to maintain internal engine cleanliness and extend the life of 4-stroke powerplants. Its primary benefit is the effective removal of harmful sludge, lacquer, and deposits that accumulate over time, ensuring your fresh oil can lubricate the engine optimally. The main caveat is that it must be added to the existing oil immediately before a scheduled oil change; it cannot be left in the system during normal operation.

FAQs

Can I use this in a 2-stroke engine?

No, this product is specifically formulated for 4-stroke engines where the engine oil and combustion chambers are separated.

Is it safe for my bike's wet clutch?

Yes, the formula is specifically tested to be safe for wet clutch systems and will not cause clutch slip.

How many cans do I need for my bike?

One 250 ml can is sufficient for oil capacities up to 4.5 liters.

Can I drive the bike while the flush is in the engine?

No, you should never drive or ride the motorcycle while the engine flush is in the oil system. Only let the engine idle while stationary.

Does this product fix oil leaks?

No, this is a cleaning agent only. It will not repair damaged gaskets or leaking seals.

How often should I use this flush?

It is recommended to use the flush during every oil change for optimal engine cleanliness, especially if the bike is used for short trips.

Troubleshooting

Engine oil is extremely thick or sludged

If the oil is heavily degraded, one application may not be enough. You may need to perform a second short-interval oil change after a few hundred miles to ensure all residues are removed.

Difficulty shifting during the 10-minute idle

This can occur if the clutch plates are heavily lacquered. Continue to pull the clutch lever steadily to help the fluid dissolve deposits on the friction plates.

Setup, Compatibility & Care

This product is designed exclusively for 4-stroke motorcycle engines. It is fully compatible with synthetic and mineral-based engine oils. When preparing for use, ensure you have your new oil and oil filter ready, as the engine must be drained promptly after the flush. If your oil capacity exceeds 4.5 liters, you will need an additional can to maintain the required concentration for effective cleaning. Always handle used engine oil according to local environmental regulations, as the flushed-out contaminants will be suspended within the waste oil.
