Purpose and Specifications

Liqui Moly 21717 Motorbike Engine Flush is a powerful 250 ml cleaning additive designed specifically for 4-stroke motorcycle engines. Add it to your warm engine oil before an oil change to dissolve stubborn sludge, lacquer, and deposits that build up over time, flushing them out completely for a like-new engine performance.

Key Benefits:

• Cleans oil circuits thoroughly without harming seals or catalytic converters
• Restores original power and smooth running by removing performance-robbing buildup
• Compatible with all motor oils and wet clutches - safe for daily use
• Highly economical: one 250 ml bottle treats up to 4.5 liters of oil

Ideal for engines operating in temperatures from -30°C to 150°C, ensuring reliable cleaning year-round. Shelf life is 4 years when stored cool and dry.

When to Use / Replace?

Use every 10,000 km or 12 months during routine oil changes, or more often if your bike has high mileage, sits idle over winter, or shows signs of sluggish performance like rough idling or reduced power. Run the engine at idle for 10 minutes after adding, then drain the old oil and filter - your fresh oil will now work at peak efficiency for the next 10,000 km.

• How often should I use it? Every oil change, especially before winter storage or after 10,000 km, to prevent deposits.
