Archoil AR6400-D Diesel Fuel System Cleaner (12 oz) Four Pack - Rapid Injector Cleaner, Turbo & DPF Deposit Control

It seemed to work fine. I didn’t notice anything different whatsoever, but I know it helps in lubrication of my cp4

1999 Volvo S70 GLT light pressure turbo, 138k. Check engine light P0234 code. Turbocharger Overboost condition. Most likely the waste gate on the turbo fouled with carbon. I am tired of working on the engine of this car. I thought I would try a bottle of Archoil cleaner. I put in the whole bottle in and filled the tank, 18 gallons. After a quarter of a tank burned the check engine light went away. And the car runs the best since I've had it. Smooth. More power and seems to be quieter too. Thumbs up. Good stuff. I'm sold.

AR6400-D works well cleaning the soot from my 6.7 Cummins. Regens extended to over 1,000 mile intervals. Will continue to use every 5K miles. A MUST product for diesel engines new and old.

The DPF warning light came on in my 2014 VW Touareg TDI Lux and it was suggested that I run a tank with this product before I spend a fortune at the dealer. (To be detailed, my tank is 26 gallons, and this bottle will treat 40 gallons. So, I used 3/4 of the bottle and filled my tank. Added the remainder of the bottle and 10 more gallons of diesel when my tank was half empty.) Voila! The light went off within driving about 50 miles and has never come back on. That was a couple of years ago and I now run an Archoil tank about every 6-7 months, for good measure. The fine folks at Archoil recommend every 5,000 miles. I'm probably near that ballpark. Great stuff!

It is great runs super great 👌

Make sure you fill your tank up and pour the hole bottle in . Run it Till the tank is almost empty and fill it up again. My truck seems to be running a lot better. Turbocharger kicks in faster I would definitely recommend it

Definitely recommend I used it on 2.8 turbo diesel truck now have more power Definitely cleaned injectors 100 % recommend 👌

About six months back, I was having a very hard time with my 2015 F350, 6.7 liter. The P2002 code wasn't clearing and it wouldn't pass an emissions test / inspection. I worked on this off and on for a few months trying to see which sensor was failing or how to force a regen cycle. There were several long runs - >1/2 hour & > 45 mpg - to clear the P2002 code but my attempts kept failing. Almost succumb to being financially abused from the Ford dealer until I poured two containers of Archoil AR6400-D into a half-full tank of diesel. Took a short trip to get the solution to saturate everything in the fuel and exhaust system then let it set overnight. Next morning, I took the F350 for a drive and the engine light went off and the emissions code(s) were gone. The pickup then passed the emissions test for registration and it also improved significantly in fuel consumption. I was getting 8.5 mpg and now - still after 6 months - get around 12 mpg on the highway and 11 mpg for shorter trips. VERY HAPPY WITH THE PURCHASE!! (And I hope that you have to same results as I did!)

Worked awesome for my system 2013 f350

It is good

My Truck was running like garbage! 2000 F-250 7.3L. Was throwing 9 engine codes, would barely start, usually wouldn't stay running, and if I tried to drive it anywhere it was an adventure, no power, could die anytime and strand you, a nightmare. So I bought this Archoil Diesel Fuel system Cleaner and Archoil9100 Friction Modifier. Expecting to be disappointed but willing to take the risk before spending big money on repairs at a garage. I dumped the products in, and tried to start the truck right away (block heater had been plugged in for hours). It was about -8C out; couldn't get the truck to run for more than 45 seconds. Did this 3 times. The next day after leaving it plugged in over night, it starts under duress, but I manage to get the rpms up to 2000 and hold them there for about 5 mins. I let the truck come back to idle and leave it idling for 30 mins. Come back outside and it's still idling, good sign, sounds good too. Decide I'll drive it 1 km down the road and see how it drives to the gas station, I needed to fill it up after all, I hadn't followed the mix instructions on the fuel system Cleaner. I baby it down the road. Fill it up. Decide to give'r a rip on the way home and it runs awesome, decide I'll rip to the next town and get a coffee, truck pulls and cruises at 120 km/h easily. 2 weeks later ish ans still running great. Also I wiped the engine codes and ran it for a few hundred kms and now only have 1 code that shows up. Awesome product.

Seems to help after flap code and diesel geeks fix.

I just love this product, it surely is worth the money a person pays. Truck is running smoother since I've put it in the fuel tank!
