AR6400-D Diesel Fuel System Cleaner
Rapidly Cleans Injectors, DPF, Turbo & Fuel System

Archoil AR6400-D Diesel Fuel System Cleaner utilizes the latest and most powerful fluid technology to deliver a cleaning service to the key fuel system components - injectors, DPFs, turbos and EGRs.
Experience restored performance, improved fuel economy and smoother idling as a result of cleaning the fuel system with AR6400-D.
AR6400-D does not cure Power Stroke HEUI injector problems (stiction). Please use AR9100 Friction Modifier instead.
Cleans Injectors
- AR6400-D rapidly removes internal diesel injector deposits (IDID) and carbon build-up from injector tips in all diesel applications
- AR6400-D ensures correct injector spray patterns, resulting in a more complete combustion and lower emissions for optimized performance
- Cleaning carried out by using AR6400-D results in more power and efficiency and less frequent regens
Removes Turbo Deposits
- AR6400-D removes carbon build-up from the turbo. Carbon build-up negatively affects turbo performance and life
- Carbon and soot deposits restrict movement of the turbine and variable vanes inside the turbo, resulting in turbo lag and less boost
- AR6400-D prevents the accumulation of carbon to reduce excess heat and wear and avoid premature failure of the turbo


Reduces DPF Deposits
- AR6400-D improves combustion which reduces carbon, soot and particulate exhaust emissions
- AR6400-D cleans soot and carbon deposits from the DPF
- Reduction in carbon and soot build-up will reduce regenerations, prevent performance loss and potential engine damage from clogged DPFs
