Restore your engine’s peak performance and fuel economy with Wünscher Fuel Injector Cleaner 300ml. This professional-grade German additive is the ultimate solution for dirty or clogged fuel systems, specifically designed to remove carbon deposits, gums, and varnishes from fuel injectors, intake valves, and combustion chambers. In the high-dust and variable fuel quality environment of Bangladesh, injectors can quickly become restricted, leading to rough idling, engine hesitation, and poor acceleration. This powerful cleaner restores the original spray pattern for perfect fuel atomization, ensuring a smoother ride, reduced exhaust smoke, and significantly better mileage.
WUNSCHER FUEL INJECTOR CLEANER 300ML (W7721) is a high-tech detergent formula engineered in Germany to provide deep-cleaning action for the entire fuel delivery system. Modern engines, particularly those with Gasoline Direct Injection (GDI) and EFI systems, rely on microscopic injector nozzles to deliver fuel at high pressure. Even a tiny amount of carbon buildup can disrupt this process. Wünscher Fuel Injector Cleaner dissolves these stubborn deposits safely, allowing your engine to breathe and burn fuel more efficiently, just like the day it left the factory.
A clean fuel system is vital for a smooth-running car. WUNSCHER FUEL INJECTOR CLEANER 300ML optimizes the air-fuel ratio, which is the key to maintaining horsepower and throttle responsiveness. Drivers in Bangladesh often notice their cars feeling “heavy” or “sluggish” in traffic—this is frequently a symptom of restricted fuel flow. By using this 300ml treatment, you ensure that every drop of petrol is perfectly misted into the cylinder, resulting in a quieter engine, stable RPMs at idle, and a noticeable reduction in fuel consumption.
Choosing WUNSCHER FUEL INJECTOR CLEANER 300ML is a smart investment in preventative maintenance. Clogged injectors can cause “lean” combustion, which increases internal engine heat and puts unnecessary stress on your pistons and valves. This German formula includes specialized corrosion inhibitors that coat the inside of your fuel tank and lines, protecting them against the moisture and impurities often found in local fuel supplies. Whether you drive a modern turbo-charged sedan or a reliable Japanese family car, Wünscher Fuel Injector Cleaner is the most effective way to keep your fuel system operating at 100% health.

Wait until your fuel tank is low (around 10–15 liters remaining).
Pour the entire contents of Wünscher Fuel Injector Cleaner 300ml into the fuel tank.
Fill the tank with fresh petrol (up to 60 liters) to ensure proper mixing.
Drive the vehicle normally; the cleaning process happens as you drive.
For best results, use every 3,000 to 5,000 KM to maintain a clean system.
Maintenance Tip from Oil House Bangladesh: If you have never used an injector cleaner and your car has high mileage (over 50,000 KM), we recommend using one bottle per tank for two consecutive fill-ups. This provides a “Shock Treatment” that removes years of built-up carbon for a total engine refresh.
