About this item

• High-Strength Concentrate: Use 5 - 10ml for every 1 Litre of fuel. 5L treats up to 1000L of diesel, making it one of the most cost-effective professional strength additives available. Cleans the entire fuel system in 1 application: DPF, EGR valve, fuel injectors, fuel pump, fuel lines, turbo, catalytic converter, combustion chamber, and glow plugs. Compatible with all diesel engines, including veh
• DPF and EGR Cleaning: Helps clean DPF deposits and restore exhaust flow; frees problematic EGR valves clogged with carbon buildup; rapidly reduces harmful exhaust emissions and unwanted black smoke from the exhaust. Regular use helps prevent future carbon accumulation in the DPF and exhaust system. Designed to help lower emissions ahead of MOT testing, making it a practical choice for pre-test die
• Restores Engine Performance: Directly addresses rough idle, hesitation, power loss, and sluggish throttle response caused by carbon deposit buildup in the fuel system. Effective on high-mileage diesel engines where years of accumulated deposits have degraded performance. Helps restore lost fuel economy by cleaning fuel injectors and combustion chamber. Also cleans turbo carbon deposits to help rec
• Advanced Proprietary Formulation: Fuel System Detergent, Carbon Cleaner, Nano Fuel Borne Catalyst, 2-EHN Cetane Improver, and Ester Lubricant. Includes the highest purity 2-EHN cetane improver for smoother cold starts and reduced combustion noise. Ester lubricant protects fuel pump and injectors against wear.
• Simple to Use: Measure and pour directly into the fuel tank before refuelling. Works as you drive with no tools or mechanical knowledge required. Add to fuel tank as part of regular diesel maintenance to keep DPF, EGR, and fuel system clean over time. Professional-grade formulation developed and manufactured in the UK. Trusted by professional mechanics and fleet operators for over a decade.
