Archoil AR6400-D MAX Pro Diesel Engine, Turbo, DPF Cleaner 400ml & AR6900-D 250ml

Ok so im not realy one to believe in snake oil hypes etc..however i think i should share this with you people out there..(perhaps to a few sceptics too..) So i had just purchased a Nissan xtrail 2.0 dci..& on the way home management light came on..(perhaps the crook trader deleted it prior!)..so off it went to my local mech & it came up with a brake switch fault/failure but it was a dealer part only.. Now i personally thought it could be the DPF as it had been stood a month or two prior to my purchase..(common issue with the xtrails of that year) & there were some tell tale signs that it may have had some neglet in regards to normal servicing.. So I trawled the net for a good DPF cleaner & this 'Archoil' popped up..so i read the reviews etc what it did for people's cars, how it improved functionality of their cars, turbo spool improved etc.. I was feeling flush that day so i thought let me waste £20..not a cheap product but i had planned a trip to Devon the following week (6hr drive) so i bought it.. Threw it all in with a full tank of 'normal' diesel, not V Power (yet)..& 310 miles later management light still lit & the car felt sluggish on acceleration as it did when i purchased it.. Drove it around there over the week & filled tank up again for the journey back. Just as if by magic at the fuel station the management light went..it LITERALLY went by its own accord!! Ok wow Brilliant..now lets see it on the motorway.. Hit the motorway & no word of a lie..the 4x4 felt ALIVE! Turbo spooled well, i got the acceleration i wanted, the overtaking was safe & comfortable..so whatever this ARCHOIL is..WORKED FOR ME!! Now whatever it did for the car, cleaned the DPF, or turbo, or exhaust, or whatever..im GLAD i bought it! 5 stars from me..(for a change! Lol!)

I was having issues with my DPF doing a regen too frequently. My differential pressures were high with the car off! I put a tin of 6400-D in and within 15 miles the soot levels started to come down slowly. I’m doing an oil change tomorrow so I want a nice clean dpf to run the new oil without a regen happening straight away on nice fresh oil, so I forced a regen on my local dual carriageway. 20 miles later I get home and I have a mere 4g of soot in my dpf, my pressures are reading 0 with the car turned off and it seems to have fixed my issues with 20 or 30 miles of using it! Incredible stuff.

I wasn’t holding out much hope putting this in my sluggish Volvo V50 130k mileage, with a very rough tick over, but the results were amazing! After about 50 miles it’s idle got so smooth, you’d barely tell it’s a diesel, then a 100 more the performance greatly increased. I can’t recommend this highly enough.

I’m always dubious of additives, after using many brands for a number of years on my diesel c class (2008), I noticed with the general brands some gains in responsiveness but not much else. Archoil so far after 500 miles has seemingly provided similar if not better results then other brands, and for the first time, I’ve seen a reduction in smoke from the exhaust on hard acceleration, but not eradicated so has prompted me to go take it down to the garage! Only negative is the packaging it came in did have a very strong diesel/spirit smell, to be expected?

My diesel filter light kept coming on. (VW passat). Used this and after 6 weeks no repeat. I'm sure the engine feels smoother (but it might be my imagination).

Added this to a full tank and did a long run and emtied the tank over the following week. I am very pleased with the results asmy Wrangler runs like new, smooth and quieter This product actually worked for my engine. Really worth the money

No noticeable difference in driving experience or MPG with my Mercedes GLE 350d. This may mean that after 58000 miles the engine was still clean enough that this treatment was not needed. I used the larger bottle in a half tank of diesel, and on the following tank I drove a 170 mile round trip that I do regularly, having filled up at my usual Esso station. The resulting MPG was as experienced before using it. The engine already ran smoothly and quietly so no improvement to report there either. Hopefully I did not waste my money and it has done some level of cleaning to keep things in good order. I've given three stars as there is no way to tell if there was any result from using this, but at least it was easy to add to the tank.

I was a bit skeptical about fuel additives. some of them seem to be nothing more than snake oil, but having had the warning light on my dashboard and a message on the screen saying the DPF was in danger of clogging up, I thought it would be worth a try. I'd done a few decent runs in my car, trying to get it to do a regen, but the error message would still come back after a couple of days. Poured a bottle of this in the tank and filled it up. It took about 40 miles of driving before the error message and engine warning light stopped giving me grief, but Archoil really seems to have cleared it out. That was a month ago, and the car is running well, and no error messages about the DPF! I can definitely recommend this stuff, and will keep using it to keep my engine happy!
