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 effectively dissolve accumulated contaminants throughout the oil system, including the crankcase, oil galleries, valve train, and piston rings. Regular use helps restore engine performance, reduce oil consumption, extend engine life, and maximize the benefits of fresh oil changes.

How to Use

Add entire contents to the engine oil when the engine is at normal operating temperature and before an oil change. One 425ml bottle treats 4-6 liters of engine oil. After adding, allow the engine to idle for 10-15 minutes (do not drive the vehicle). Immediately drain the oil while hot and replace the oil filter. Refill with fresh oil of the appropriate grade and specification. For severely contaminated engines, a second treatment may be beneficial at the next oil change.

Engine Flush is particularly valuable for vehicles with extended oil change intervals, high mileage, or those displaying symptoms of oil system contamination such as ticking noises, reduced power, or excessive oil consumption. This product should be used as part of regular maintenance every 15,000-30,000 miles or whenever signs of oil system contamination appear. For maximum engine protection, follow with premium quality engine oil and consider Wynns Oil System Treatment for ongoing protection. Not recommended for use in motorcycles with wet clutches or engines with known mechanical issues.
