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

Works like a dream. Getting 2-3 more MPG.

2017 Nissan 5.0 diesel Love it drive and performance is Great 4 more Miles per gallon on HWY just like a new engine tail pipes nice and clean I recommend running so smooth

Use this for the first time on my 2015 Ram 3500 6.7 as I was noticing frequent regents. Was truly impressed. Noticed the difference pretty early in on performance, pickup and haven't had a regen since adding. Will be adding this to my maintenance cycle when I change oil and filters. Would definitely recommend.

I just used this in my kabota L2501 tractor. I'm very satisfied with the performance of this cleaner. My tractor only has 200 hrs, but began to suffer fuel injection issues and severe loss of power. I received the cleaner this morning, mixed with diesel fuel and mowed 2 acres. Maybe half way thru the engine began sounding better, by the time I was done my engine is back to normal 😎. Total running time was approximately 1.5 hrs. HIGHLY RECOMMEND THIS PRODUCT

This stuff is the best,i had a check engine light come on ,i pulled the code and it was the EGR,i figured it was dirty and was going to pull it off and clean it. That is a big pain but my nephew told me to first try this and if worked very quickly.

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

Can’t explain it, but this stuff works! Improved mileage, fewer regen cycles. I was a skeptic now I’m a believer.

Archoil AR6400- Diesel is one of the best on the market. I have a GMC 3.0 Diesel which like most newer vehicles, use "direct intake" vs a fuel rail.The Archoil AR 6400 helps clean the engine for carbon build up, especially lthe backside of the pistons. I've seen an increase in mileage where usual mpg is about 29 to 30, after the treatment I'm experiencing 33 on the hwy. ALSO,I use Archoil AR 6500 at every fuel up for lubricity.

tres bien

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.

Work very well seems to do the trick

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!

Came highly recommended. No disappointment
