Product Description

AR6400 is a powerful next-generation fuel additive blended from the latest high-strength polyetheramines that quickly and safely remove gum, varnish and carbon deposits from the fuel system and engine. Advanced combustion modification chemistry then maximizes combustion performance to help remove post combustion hydrocarbon build-up whilst rapidly reducing harmful exhaust emissions. AR6400 quickly restores lost engine performance and fuel economy in addition to unique properties that help protect surfaces from further deposit build-up. Molecule by molecule deposits are safely removed from intake valves and piston tops thus improving combustion efficiency and reducing the propensity for pre-ignition. AR6400 is suitable for all 4-cycle gasoline engines, including ethanol blended fuels and biofuels. AR6400 is not suitable for 2-cycle engines.

5.0 out of 5 stars ARCHOIL AR6400-D 11 Nov 2013
Verified Purchase
Looking at a potential turbo replacement on my Seat Leon 2.0 TDI even though its only six years old ,serviced every year and only done 50K i did a lot of research for a solution for a turbo overboost problem which lit the EML warning light and periodically put the car in "limp" mode.I came across Archoil.Having read the info i decided to try this product.Having put it in the tank and added 50 ltrs of diesel (,thats all you need do ).Within 20 miles i noticed a difference to the cars performance ,it was more responsive and felt smoother. After 150 miles the EML light went off!!!!Thanks Archoil I recommend this product to everyone .Pity Seat dont endorse this product. Even my local dealer asked what i had done to the car .

5.0 out of 5 stars EXCELLENT PRODUCT 16 Sep 2012
Verified Purchase
i have a diesel car which has been frequently mis-firing and recieved an Archoil 20ml sample from a previous order i had made on Amazon and after using this product my car has stopped mis-firing altogether,the engine is running smoother with a lot more go,its doing much more mileage to the gallon and has lowered my vehicles emissions greatly,this is an Excellent Product and does the job well,the only other product that i have used that also works quite well is advanced redex but i dont think its as good as the Archoil formula,i would highly recommend this product to anyone with a car diesel engine that needs to give their engine a good clearout,to improve engine efficiency and performance

4.0 out of 5 stars Early days but has shown some improvements. 16 Aug 2013
Verified Purchase
I noticed some improvement in the acceleration quite soon after adding this solution to the tank. I do still get a puff of smoke on starting up and the tickover whilst not fully warm is still a bit lumpy. I have to be honest it is no where as bad as it was. I have noticed a 3mpg improvment on my short runs but it is still early days and I have yet to give it a long run. End of the day my car has done 74000 miles so may be other underlying problems. Well deserved 4*.

5.0 out of 5 stars After 1 month's use 21 Aug 2013
By Steve
My engine is a 3.6ltr V8 diesel and I started to experience issues with the rev counter fluctuating between 600 & 900 rpm on tick over. On many occasions after a few minutes of city driving I would receive dash notifications that there was an engine management fault. I took the vehicle into my local JLR specialist garage only to be advised that it was very likely that I was experiencing an injector failure, and that all eight may need to be removed and cleaned. That's a 7 - 9 hour job in labour terms (say 500). A further specialist cleaning of injectors at 50 each, or new ones could be required, 450 each (plus reprogramming each injector into the engine's ECU). Absolute worst case scenario: replace all eight injectors. All prices + VAT.

Following a bit of research on injector / combustion cleaning products, and viewing web forums, I discovered AR6400-D, which I promptly purchased to try to resist a x,000 garage bill. Added it to the tank in the prescribed ratio, and before half of the tank had been used, the problem had gone. The rev counter now sits without fluctuation where it should be, the commonly associated diesel clatter noise has gone, and the V8 diesel sounds much more heathy. I've not bothered measuring fuel consumption since I usually only receive between 14 and 27 mpg anyway. I made that decision when I bought the car (although it's "greener" than the car it's replacing).

I'm currently using a course of AR6200 and avoiding supermarket fuel, and although now slightly more expensive to run per mile, in the long term it should save thousands if that's what cheap fuel does to the injection and combustion chambers of cars.

Would absolutely recommend this product without hesitation.

3.0 out of 5 stars Added - can't so any harm ! 23 Jan 2014
By SO8
Well, I have added a bottle of this stuff to my 330d LCI BMW engine ... and noticed nothing - but that is roughly what I expected.

The website for the manufacturers is great but this is stuff you are never really know is working unless you already have an issue. I figured it can't do any harm and is supposed to be far more powerful a cleaner than any 'super diesel'. With modern engines having to comply to strict emissions control the DPF can get clogged and anything that helps keep everything clean has got to be worthwhile if you are keeping a car ! The DPF doesn't benefit directly from this but if a car is running cleaner and combustion is better it is going to give the DPF an easier time.

I have seen the insides of Vauxhalls run on normal diesel at work that have been totally clogged with soot/carbon and needed cleaning - so thought this is worth a go !

5.0 out of 5 stars Excellent product. 24 Dec 2013
Verified Purchase
Used in Ford Focus 1.8tddi (115,000miles) before MOT. Did a 200 mile trip after applying to the tank. Emissions were nearly zero or very very low on lambada tests - lower than last years results. Will be using again when necessary.

5.0 out of 5 stars It Actually Worked! 14 May 2014
Verified Purchase
I have always been skeptical with regard to the claims of most petrol additives however I had a 420 error come up on my xType (Cat low efficiency). This would normally mean replacing the cat with over a 1000 bill. A friend suggested I try an engine/ injector cleaner. I thought why not? After all I had nothing to lose. I chose this one as the claims seemed slightly less outrageous than many of the others on the market. I followed the instructions and after about three quarters of a tank the light went out without even being reset. It has been out now for more than a week. I really don’t believe it but this Archoil seems to have actually worked!
