Love this product, seems to work great.
I have a 03 Duramax with 280,000 miles on it. Second set of injectors at about 200,000. The AR6500 has improved power, MPG, and seems to be a lot quieter. I am on my 4th tank of fuel so far I am happy.
This product works great either in my Dodge Ram diesel or my wife's Range Rover. Better mileage, runs smoother and even quieter with my Cummins
Thanks for a great ptoduct'
My truck with 190,000 miles seemed to be tired and suffering from stiction problems. I was contemplating a costly injector replacement. At my next oil change I added AR9100 Friction Modifier and AR6400 Fuel System Cleaner. Immediately it ran quieter and I noticed some smoke under hard acceleration as the cleaner did it's work. The stiction symptoms went away quickly, mileage improved and overall the truck ran like new. I started using the AR6500 and it continues to run great.
Last month I replaced the EGR cooler, high pressure oil pump and did the "blue spring" update ( before I had any issues ) and asked the shop to service the turbo while it was out as well as look for any other potential problems. They called during the service and said the turbo didn't need any cleaning or service as it looked great. It was returned to me a day earlier than promised.
I will continue to use these products.
I have tried most all of the higher end diesel fuel additives in my Daimler-Benz diesel with the OM642.826 engine. Always spiking my additive alchemy with AR6200. AR6500 is by far the best fuel additive I have tried. I have noticed improved throttle response and diminished turbo lag as I log the miles with AR6500. Mileage between regens is also slowly but steadily improving. MPG is a bit better than my last fuel additive mix as well. While this product is no quieter at operating temp idle, it is quieter under acceleration before the engine is up to operating temperature.
