MANNOL 9957 Injector Cleaner is a universal fuel system cleaner formulated for petrol engines. It is designed to work with multipoint injection (MPI) engines, direct injection (GDI) engines, and carburetor-based systems. Developed using a latest-generation detergent package, it cleans the fuel supply path from the tank through to the injector nozzles — without any disassembly of engine components.
This product is suitable for all atmospheric and turbocharged petrol engines. It is also recommended for engines equipped with exhaust gas after-treatment systems, including catalytic converters — the formulation is safe for use with these systems. A single 250 ml bottle treats up to 50 litres of fuel.
For Indian car owners dealing with GDI carbon buildup, rough idling after city driving, or reduced pickup — this additive is a practical, low-cost maintenance step between service intervals. Regular use helps keep injectors calibrated to their original spray pattern and prevents heavy deposit accumulation over time.
Key Benefits
Cleans without disassembly — works through the fuel circuit during normal driving; no workshop visit required for routine injector maintenance.
Restores throttle response and pickup — removes deposits that choke injector spray patterns and disrupt the air-fuel mixture.
Reduces fuel consumption — clean injectors atomise fuel more efficiently, improving combustion completeness.
Smooths out rough idling — particularly effective for city-driven cars where low-speed carbon buildup occurs faster.
Safe for catalytic converters — formulated to be compatible with exhaust gas after-treatment systems; will not damage emission control components.
Works across injection types — compatible with MPI, GDI, and carburetor-based petrol engines, both naturally aspirated and turbocharged.
Meets latest detergent standards — developed with a next-generation detergent package for effective cleaning at the recommended dosage.
Standards / Approvals Met:
No OEM-specific approvals are listed for this product in the manufacturer's documentation. It is formulated in accordance with the latest generation detergent standards.
