HIGHTEC Injector Cleaner Diesel is a high-strength fuel additive that targets the heart of the diesel fuel system. It dissolves stubborn deposits in the injectors and combustion chamber, restoring precise fuel atomisation. With clean injectors the engine regains its performance and drivability while burning fuel more completely.

Purpose and specifications

This product is intended for all diesel engines, from older designs to modern high-pressure common-rail units that are especially sensitive to injector fouling. As a universal service additive it carries no vehicle-specific OEM approvals and suits mixed diesel fleets. It cleans the fuel system and combustion chamber, ensures efficient combustion and helps lower fuel consumption.

• 0.250L container, enough to treat a full tank of up to 50 liters of diesel
• Remains effective across the engine's normal operating temperatures and works continuously while driving
• Cleans clogged injectors and combustion chamber to restore smooth running and full power
• Improves combustion efficiency, which helps reduce consumption and emissions

When to use / change?

Choose this cleaner when you notice hesitation, power loss, rough idling or higher fuel use, and use it as a preventive treatment about every 5,000 km. Add the bottle to the tank before refueling, then drive as normal so the additive works throughout the system. It is stable across a broad operating temperature range. Shelf life is approximately 5 years when stored sealed in a cool, dry place.
