RESTORE DIESEL INJECTORS

CLEAN INJECTORS

• Rapidly removes internal diesel injector deposits (IDID) and carbon build-up from injector tips

• Ensures correct injector spray patterns, resulting in a more complete combustion and lower emissions for optimized performance

REMOVE TURBO DEPOSITS

• Clears the turbine and variable vanes of soot and carbon, reducing turbo lag and restoring boost

• Prevents the accumulation of carbon to reduce excess heat and wear, avoiding premature failure of the turbo

REDUCE DPF DEPOSITS

• Improves combustion to reduce carbon, soot and particulate exhaust emissions

• Removes soot and heavy carbon deposits from the DPF

• Reduces regen frequency

• Prevents performance loss and potential engine damage from a clogged DPF

Revived a rough running 7.3

I put a bottle in a tank of old diesel fuel in an E350 (370k miles) that had been sitting for a year. It ran for a few miles then must have picked up algae and started running rough. After changing the fuel filter and adding the AR6400-D it’s cleared right up and continued to run really well. I’m about 200miles in now with topped off fresh fuel still running good.

I have a stock 2009 6.7 Cummins with 85k miles. for the past year my mpg has been decreasing little by little The best mpg was 12.5. I used one treatment of the AR 6400-D diesel fuel system cleaner. It took about two hundred miles before I noticed any change. Happy to inform you all that my mpg increased to 19.6. Very satisfied with this product!!

Good result

2002 5.9 liter 24 valve, 150,000 miles. Throttling during idling. This symptom has persisted even after treating the fuel with injector cleaners.
After using two treatments of AR6400-D that idle throttling has subsided.
This saves me from pulling the valve cover and removing the injectors for cleaning or replacement.
This is a positive result in my book.
