Achieve a professional-grade engine clean in just 10 minutes with Wünscher Engine Motor Flush 443ml (W7713). This ultimate rapid-action German formula is engineered to dissolve and suspend stubborn sludge, carbon deposits, and wear particles within your oil system. Specifically designed to unclog hydraulic valve lifters and Variable Valve Timing (VVT) systems, it restores oil pressure and engine efficiency. Safe for all petrol and diesel engines—including those with turbochargers and catalytic converters—this high-capacity 443ml can ensures your fresh oil stays clean and performs at its peak from the very first kilometer.
WUNSCHER ENGINE MOTOR FLUSH 10MIN 443ML (W7713) is a specialized cleaning concentrate developed by Wünscher Germany to eliminate performance-robbing contaminants. Over time, internal engine components accumulate “mud” and oil-insoluble residues that interfere with smooth operation. This potent 10-minute formula brings these impurities into suspension, allowing them to be completely flushed away during your oil change. By cleaning the entire lubricating circuit, it prevents the immediate contamination of your expensive new oil, extending engine life and maintaining factory-spec performance.
Modern engines with Variable Valve Timing (VVT) and hydraulic lifters are extremely sensitive to oil purity. WUNSCHER ENGINE MOTOR FLUSH W7713 is precisely formulated to reach these tight tolerances, removing the varnish that causes lifter “tapping” and VVT sluggishness. For drivers in Bangladesh, where extreme heat accelerates oil oxidation, this flush acts as a vital reset for your engine. It neutralizes aggressive crankcase acids and restores the elasticity of piston rings, which improves cylinder compression and reduces oil consumption.
Choosing WUNSCHER ENGINE MOTOR FLUSH 443ML (W7713) means choosing German reliability for your vehicle’s heart. Unlike generic flushes, W7713 is mixable with all synthetic and mineral oils and is safe for use in vehicles with sensitive exhaust after-treatment systems. The 443ml high-volume can is sufficient for oil systems up to 6 liters, making it the perfect choice for SUVs, premium sedans, and light commercial vehicles. It ensures that 100% of your new oil’s additive package can focus on protection rather than cleaning up old residue.

Bring your engine to normal operating temperature (warm to the touch).
Pour the entire contents of Wünscher Engine Motor Flush W7713 into the old engine oil.
Start the engine and let it run at idle for exactly 10 minutes. (Important: Do not drive or rev the engine during this time).
Turn off the engine and drain the old oil while it is still warm.
Replace the oil filter and refill with fresh, high-quality motor oil.
Maintenance Tip from Oil House Bangladesh: To keep your engine in showroom condition, we recommend using W7713 at every oil change. This is especially important for turbocharged engines where carbon-free oil passages are critical to prevent expensive turbo failure.
