MANNOL 9958 DPF Cleaner Diesel Additive – 400ml

The MANNOL 9958 DPF Cleaner (400ml) is a professional-grade diesel fuel additive designed to clean and regenerate clogged or underperforming Diesel Particulate Filters (DPF) without dismantling the exhaust system. It is part of MANNOL's Car Care additive range, manufactured in Germany under the MANNOL brand — a name trusted by automotive professionals and enthusiasts across the world for over two decades

MANNOL 9958 DPF Cleaner addresses this by working directly through the fuel system. Added to the fuel tank before refuelling, the additive mixes with diesel and reaches the DPF during normal combustion. It is suitable for all diesel engines — both naturally aspirated and turbocharged — and is compatible with diesel vehicles equipped with automatic DPF regeneration systems as well as those without such systems. It is especially recommended for cars used frequently in city traffic or running on lower-quality diesel. Regular use every 2,000 km helps maintain the DPF at near-factory efficiency and delays or prevents costly forced regeneration or filter replacement.

Please confirm compatibility with your vehicle before placing the order.

4. Key Benefits

Cleans without dismantling: Restores DPF efficiency through the fuel system alone — no exhaust system disassembly or workshop visit required for routine maintenance use.

Prevents costly DPF replacement: Regular use every 2,000 km keeps soot accumulation in check, reducing the risk of irreversible filter blockage and the high cost of DPF replacement or forced regeneration.

Works on all diesel engine types: Effective on both naturally aspirated and turbocharged diesel engines, regardless of whether the vehicle has an automatic DPF regeneration system.

Ideal for city-use vehicles: Particularly effective for cars that rarely reach the highway speeds needed to trigger passive regeneration — the exact condition where DPF clogging is most common.

Protects against low-quality fuel damage: Helps counteract the accelerated soot buildup that results from using lower-quality diesel, which is a practical concern for everyday Indian driving conditions.

German engineering, consistent quality: Made in Germany by MANNOL, a brand with over two decades of manufacturing history and certifications from leading international automotive organisations.

Simple dosage, no special tools needed: One 400ml bottle treats up to 60 litres of diesel. Add to the tank before refuelling — no equipment, no expertise, no downtime.
