AR6400-D is a highly concentrated one-tank fuel system cleaner to be used every 5,000 miles. AR6500 cleans and maintains the fuel system and adds cetane for a boost that can be felt at every fill-up.
AR6400-D is suitable for all diesel vehicles, including newer systems such as High Pressure Common Rail.
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!!
Smoothed my idle out a little bit. My truck never had cold start issues and I've heard that's where you notice it the most. Decent product for 20$
Used the product my check engine light was on telling me my exhaust sensors were in need of cleaning put a bottle of cleaner in my diesel ran awhile check engine light went off gave me good mileage will the 6400 to keep it clean great product
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.
