Seems to work
2009 Cummins 360 ISL in a 36 Ft Motorhome, over 100k miles. I was experiencing frequent regen issues. Prior to leaving for annual winter travels, I added 2 bottles to my 100-gal fuel tank. Experienced higher temps on a couple of occasions, since then normal temps. Smoother acceleration and a slight bump in MPG. I will be adding the regular treatment every time I fuel. e

AR6400
2014 F-550 had warning lights on stating regen was needed. not having a way to regen engine without travelling 2 hours to a mechanic, I tried the AR6400 because I had nothing to lose. I ran 3 tanks of fuel through the engine and all the warning lights were cleared. I havent used the AR6500 yet, but if it perfomes like the 6400 it is money well spent. I would further like to thank Archoil for replacing the entire order when one bottle was damaged in shipping. they are a very upstanding company and I will buy from them again. Good product.
