Wynns Engine Flush 425ml

Part Number: WYN51265

Wynns Engine Flush is a powerful oil system cleaner designed to remove harmful sludge, varnish, and deposits from internal engine components before oil changes. This professional-grade 425ml formula contains specialized detergents and dispersants that dissolve accumulated contaminants throughout the oil system, including the crankcase, oil galleries, valve train, and piston rings. Regular use helps restore performance, reduce oil consumption, extend engine life, and maximize the benefits of fresh oil changes.

How to Use

• Add entire 425ml bottle to the engine oil at normal operating temperature before oil change.
• One bottle treats 4–6 liters of engine oil.
• Allow the engine to idle for 10–15 minutes (do not drive).
• Drain oil immediately while hot and replace the oil filter.
• Refill with fresh oil of the correct grade and specification.
• For heavily contaminated engines: repeat at the next oil change if necessary.

 

Engine Flush is especially valuable for vehicles with extended oil intervals, high mileage, or symptoms of oil contamination such as ticking noises, reduced performance, or increased oil use. Recommended every 15,000–30,000 miles or when contamination is suspected. For maximum protection, follow with premium engine oil and Wynns Oil System Treatment.
