Great stuff best in my review

My check engine had came on and it was my Turbo Actuator so I ran Archoil for a couple of tanks of Fuel and the light went off and next came back on

Pros
  • I don't know if it helps with millage I could not see any. I use it to help save my fuel pump
Cons
  • The cost of the Complete Diesel Fuel System Maintenance Kit may be too high for some individuals, making it unaffordable

no known difference in mpg

My 05 built dmax didnt seem to show any improvement. Took a 2100 mile trip to the rockies and back so I burned up 6 tanks of fuel and did the same trip last year and I had to fill up at the same locations and I didn't have any additives last year. Maybe does things for other vehicles but I could have spent the 50 dollars on something better for my dmax.

Pros
  • Cuts down on smoke and adds power
Cons
  • The kit may be difficult to use for individuals without prior experience in diesel fuel system maintenance

Awesome stuff best in my review

I can notice a big difference in how my 7.3 runs I had the typical OBS bad sending unit in both tanks after running the injector cleaner by golly both gauges work again. The ctane boost is awesome as well I will run only archoil from now on 👍🏼👍🏼👍🏼

Pros
  • My truck regenerated less and increased my mileage per gallon really helped when towing!
Cons
  • The AR6500 Diesel Treatment may not have long-lasting effects, requiring frequent reapplication

I will continue to buy

I will continue to buyI haven’t noticed any changes in fuel economy or anything like that but I do like to use in my truck. The packaging may be bulky and take up too much storage space.

Pros
  • Works great could tell a big difference
Cons
  • The packaging may be bulky and take up too much storage space

I use this with every refuel.

I put this in my fuel tank with every refuel.Diesel fuel can get nasty, this will ensure your engine keeps running without nasty fuel.

Pros
  • So far so good
Cons
  • Noticed worse feeling economy. That's it. Hopefully it's doing it job internally.

Good but messy - my new review

I recently used this in my 2015 Jeep Grand Cherokee Ecodiesel with around 49k miles, first time using any additive. I used half of the cleaner at a time and ran it through two tanks and now using the fuel treatment/cetane boost. It seems to be working and I’ve noticed a bit more power and responsiveness once past the turbo lag. I will keep using this product, the only issue I have is that I can’t seem to not make a mess when measuring/adding this to my tank and the measuring part of the bottle…

Pros
  • Great
Cons
  • The AR6400-D Diesel Fuel System Cleaner may contain harmful chemicals that could be hazardous to the environment

Disappointed! Packaging/bottles leak.A LOT!

I have a 2011 Volkswagen Jetta TDI Sportwagen and recently the DPF light came on. I researched different options and products for over a week. After reading positive reviews I went ahead and purchased the Archoil Diesel Fuel System Kit. I ended up having to go out of town the day was delivered for a family emergency. When I returned I open the packaging and found that the bottle had leaked sometime during shipment but it was unfortunately past the 30-day return window. I went ahead and cleaned…

Pros
  • visiable fuel econemy i also use less deff
Cons
  • The instructions may be poorly written or difficult to understand, hindering the product's effectiveness

Best Buy for my 97 7.3 turbo diesel

Amazing stuff put new life into my truck no spitting and sputtering. For 257k miles she runs like she did 10 yrs ago! The AR6400-D Diesel Fuel System Cleaner may not be effective in removing stubborn deposits and impurities in the fuel system.

Pros
  • I use it on a regular basis in my F250 2014 diesel 6.7
Cons
  • The AR6400-D Diesel Fuel System Cleaner may not be effective in removing stubborn deposits and impurities in the fuel system

Good stuff Timmy! good for me

Makes my Cummings giggle. Have you heard a diesel giggle? If not, you NEED this combination. I've got a friend with a 7.3 and rumor is there was outright moans of pleasure coming of the garage after using it on his happy horse. Good stuff Timmy!

Pros
  • slowly clearing back smoke as stated by other reviewers
Cons
  • The scent of the AR6500 Diesel Treatment may be unpleasant for some users, making it difficult to tolerate

I buy this all the time

I am a firm believer this stuff works. I use it religiously and can see the difference. but to each his own. Thanks for attention.

Pros
  • did just like it said it would
Cons
  • The product may not be readily available in all retail stores, making it difficult to purchase
