Review on Restore Your Diesel Engine Performance With Archoil AR6400-D Fuel System Cleaner by Richard Miller

This stuff is AMAZING. I have an 04 5.9 dodge cummins. I had an injector on the way out. Super rough high idle, running rough between 50-60mph. I looked up a set of injectors. $700 for just the parts. I seen this advertised on facebook before. It's only $25. I thought "well I've spent $25 on dumber things" and clicked order. Dumped it in the tank with the next fill up. Half way through the tank I didn't feel much difference. I was driving it like an old lady for the time being because of the injectors. I decided that I should try driving it hard because driving like an old man wasn't working. Got in the throttle on the highway on ramp a couple of times and it started to smooth out. Tried some more spirited accelerating for the rest of the tank and by the end of the tank my injectors were fine! No more lumpy stuff between 50-60 and a super smooth high idle. If you're on the fence about try it I'd say go for it! You can't tell me you haven't spent $25 on dumber things.
