My father has an old boat with two TAMD61A marinised lorry engines. They are 6 cylinder, inline turbodiesels. Each engine has its own 1000L tank. They haven’t had a fuel line clean in 32 years.

I imagine that to get to an effective concentration of your additive I would need to buy a great deal of it which would possibly be very expensive and wasteful. Would you be able to advise me of the minimum effective concentration required I can decide how to proceed. It may be better to rig up a temporary 50 litre fuel container to run the engine from.

Regards
Richard

  Just because the fuel tanks are large doesn’t mean you need to treat with a full tank of fuel. Run a full bottle of Startron diesel cleaner through it (half a bottle per tank). A single 250ml bottle will treat up to 1000L of fuel so with each tank approx. 1/2 full that would be perfect.

Hiya, I have regularly used Archoil 6400 d max on my 2L diesel ford. It is due another dose, however I have recently had a new CAT fitted and wondered if this may damage a new CAT?

Read your article re using AR6400 D-Max. I have a 2016 VW Touareg V6 3.0l diesel 64000 miles. Only had the car for a few weeks and have done 3,400 miles since purchase after vehicle had been fully serviced as part of the purchase process. Engine Management light has just come on indicating fault in exhaust. Suggestion from manual get a technician to check VDCS code and get car sorted. Booked in for checking and repair in 2 days time, under 6 month / 6000 purchase warranty. So I am sure it may be sorted for me ….. fo now !! How much AR6400 D-Max additive do you put into a tank full. Touareg tank capacity is 75l. Thanks

Hi, need advise on my 2017 bluehdi 2.0 Peugeot Boxer diesel !
The engine has only done 7000 miles and in a motorhome, it’s unlikely to do more than 5000 mls a year, however these are long miles, no short runs.

Can I safely use your products in this engine?

I recently bought a “neglected” Volvo V70 2.4D – I estimate it had been neglected for the last 50k or so (it’s done 168k) (I had to put 2 L of oil in the engine before the dipstick showed normal!) – I had the car serviced by my local garage, but I was still left with a (serious) problem that every time I put little too much power on ( & sometimes, on just a slight incline) it went into Limp Mode.. and had to be restarted… After reading your website, I put Archoil AR6400D-Max into a full tank of fuel – the problem cleared after around 40 miles – I pulled my Caravan last weekend, the engine started heating as I pulled up Dinmore Hill near Hereford at 50 MPH.. revving around 4k – No more problems – I suspect my Turbo was sticking – but after Archoil the whole engine feels smoother and more responsive. I am now a “Believer”… I will continue the treatment using AR6900D.

Hi my name is Dave i have read most of what you have said on your website and i am impressed with what you say now i have got quite a few big problems firstly what is the ECU is it the sensor that is on the dpf filter and it gives the right or wrong readings that is my guess because in your letters you say that a lot of peoples problems think it is a dpf problem when it is the ecu for giving a false reading. right now lets get down to my mega problems now my ENGINE MANAGEMENT LIGHT has been off and on for 3 weeks because i went first to the garage and they put it on the diagnostic machine and it came back as exhaust GASSES problem so he said that it is my dpf filter because i told him the problems i was having the minibus kept CONKING OUT WHEN I WAS DRIVING THE BUS AND I KEPT ON LOSING POWER AND I HAVE NO TURBO. SORRY I HAVE GOT A FORD TRANSIT TURBO DIESEL 2013 IT has done 92000 miles.So my friend has told me THAT IT IS A DPF PROBLEM AND NOW I HAVE GOT 2 ENGINE MANAGEMENT LIGHTS ON.WE PUT IT ON THE DIAGNOSTIC MACHINE A COUPLE OF DAYS AGO AND HE PUT THE LIGHTS OUT FOR ME AND THEY JUST CAME BACK ON 2 MINUTES LATER SO I BOUGHT DIESEL CLEANERS DPF AND TURBO I HAVE ONLY ADDED THE DPF CLEANER AND TOOK IT FOR A 30 MINUTE RUN AT OVER 50 MILES AN HOUR CONSTANTLY. SO NOW I AM GOING TO TRY WHAT YOU SUGGESTED IS TO GO FOR A DRIVE AND GET DRIVING TEMPERATURE AND THEN DROP IT DOWN 2 GEARS AND DO OVER 3000-3500 REVS A MINUTE THE QUESTION THAT I AM GOING TO ASK YOU IS THAT HOW LONG DO I DRIVE THE VEHICLE AT THE HIGH REVS IS IT 10-20-30 MINUTES CAN YOU LET ME KNOW ASAP,AND I AM GOING TO BUY ALL YOUR CLEANERS AND ADDITIVES AND HOPEFULLY THAT WILL CLEAR ALL MY PROBLEMS THANKS FOR LISTENING CHEERS I AWAIT YOUR REPLY DAVE.

  Get the engine up to full operating temperature. Then, on a main 60mph or 70mph road, drop down a gear or 2 to get the revs to 3K. Hold for approx 30 seconds. If this doesn’t work then the DPF doesn’t require a regen or there is another underlying issue.

I have a BMW X3 3.0SD 56 plate. It pulls somewhat when accelerating hard. I
put it in for diagnosis and on a Balance test it came back with the
following figures:

Cyl 1 = -1.51
Cyl 5 = -0.10
Cyl 3 = 1.54
Cyl 6 = -1.82
Cyl 2 = 4.46
Cyl 4 = -2.56

I was advised that it was probably (note probably) Cyl 2 injector causing
the problem. I was then quoted Â£600+ to replace it.

Will your product clean the injectors??

Being new to diesel motoring, what is the difference to a DPF and a EGR. Would one cleaner for one not clean the other? If not, is there a brand/cleaner I could use to clean everything in one go?

Many thanks

  The EGR recirculates some of the exhaust gases back into the air intake. It is essentially part of the air intake. The DPF is part of the exhaust system and is designed to capture any remaining particulates. Cleaning efficiency is simply a matter of positioning. Heat is necessary to clean and the exhaust, including the DPF retains heat. The EGR, however, is designed to cool recirculating gases so cleaning efficacy is reduced considerably.

Hi,

I have a Range Rover Classic 3.5 V8 EFI from 1986 with 110.000 miles (180.000km) and I would like to do an engine clean.

In my Audi I already used AR2300 + AR9100 + AR6400D, but as the Range Rover has 30 years and some miles I don’t know what is safe to use.

What you suggest?

  The problem needs to be correctly diagnosed first. If you have replaced the plugs then replace/swap the coil pack. If the coil pack is ok then test the fuel injectors and carry out a compression check.

I have Nissan Xtrail 2015, done 7k in last six month, regularly using this car for long drives once a week and inspite had a engine management light last month. Taken to Nissan garage, done some work and as soon as I took the car out of Nissan garage, again greeted by engine management light followed by Lipm mode, had to call AA. Now the bill is £2500 as they had to replace the DPF which was completely blocked and forced regeneration was declined. Totally frustrated, Nissan do not cover this under warranty, Now looking for suitable fuel additive to run the car until get it replaced with patrol one.
Your advise would be highly appreciated.
thanks

  A blocked DPF RARELY needs to be replaced. In almost all cases a professional in-situ flush (approx. £200) will clean it sufficiently to enable a forced regeneration through a diagnostic tool. Then ensure the fuel system is cleaned with a high quality cleaner and check other systems such as the EGR are not blocked etc. Improving the quality of the oil (or fortifying with an additive), using a fuel catalyst/conditioner such as AR6200 (now AR6900-D MAX) and providing the necessary conditions to get the emission control system up to full operating temperature on a regular basis will keep the particulate filter running more efficiently.

Should I give it a blast with AR 6400-D, and then regular AR 6200 treatment ? It has an 80 Ltr. fuel tank, how much of what do I need to get.

  Hi, 1 x AR6400-D 430ml will be fine. AR6200 is a good choice and is treated at 10,000:1. The size of bottle depends on how much fuel you are looking to treat and for how long.

We have a 2005 Suzuki Grand Vitara 2.0 td, 76000 miles done. We used to 12000 miles a year and did not have any problems with the car. However, over the last couple of years we have done half that with many shorter journeys of around 30 to 60 miles. We have had the engine check light come on regularly with fault codes pertaining to glow plugs and the egr valve. The valve was replaced but the light continued to come on. Valve cleaner was used twice. In fact the light tended to come on during trips to the airport on the motorway at 70mph. Just had it sorted again at a service last week and decided to do a bit more research. Reading the comments on your page, our problems seem to fit in with the pattern.

Hi,
I recently purchased a citroen c4 1.6 hdi 2005 reg with 99000 on the clock. I took it on the motorway for a test and the dpf light came on as faulty… no power loss even at 80mph . Called the RAC to ensure if it was safe to drive back. Whilst waiting for RAC gave it a good blast on the revs while idling and switched off. RAC arrived to find dpf light off but advised to change dpf should it come on again. when I got back on the motorway the dpf light came on again. I did not bother but drove home, gave it a good blast and the light is gone again. Want to clean dpf..what do you suggest i do?

Hi there, I’m running a Ford Mondeo 2.0L TDCi with 74K miles. When your just cruising along feathering the throttle the car sometimes misses a little like it’s dying and it’s a bit smokey when your hard on the accelerator. Which of any of the products would you recommend.

  Hi, they are broken down particle by particle, disolved and then combusted. It is important to understand that carbon is still a fuel, but just solid rather than liquid. With the correct catalysts it will burn and combust just like a liquid fuel.

Hi, I have a Peugeot 807 2.2 HDI 85.,000 miles. The light management comes on and off very frequently, the message displayed is “Anti Pollution Fault”, also now “Diesel Additive minimum level” is displayed. I put 3 litres of additive 3 months ago, I thought it would last longer than that. The performance of the car has deteriorated drastically, especially when the light management is ON. The car stuggles to do 50 miles per hour on any uphill roads, I can get the car to run 70mph on a flat road, just about.., acceleration is poor too…

Brought a second hand very low mileage BMW X3 2.0d Sport. Had it serviced at BMW and they wanted £2k to decoke the engine (yellow engine warning light was on and the car had been used for lots of short trips in traffic). Put in a can of BG244. Engine warning light is now off and car runs much better. Fuel consumption is still low 30’s when I would expect high 30’s given I drive a lot on the motorway at a steady 70 mph (ish). Engine warning light still comes on from time to time but car benefits from a good red line rush thru the gears and that usually fixes it ! I have just finished the tank which had the BG244 in, is it too soon to add another can in the hope that it will completely clean out the coked up engine?

Also use AR9100 in with the oil as this should help reduce oil consumption and prevent polymerisation of oil in the intake system (including the EGR). Regards.

  Hi, for an initial treatment/reactive clean use one of the products here http://www.powerenhancer.co.uk/section.php/182/1/diesel-particulate-filter-cleaners–dpf–and-catalytic-convertor-cleaners-. For proactive maintenance and to prevent any future excessive build-up I would strongly recommend AR6200. The fuel modification technology in this product will lower the hydrocarbons during the combustion process and thus give the DPF a much easier time. It comes into its own during cold startup. It improves the quality of combustion by lowering the temperature at which the fuel can burn so again, the hydrocarbons are much less even on short journeys or when the engine is not yet up to temperature. Regards.

I have a VW Passat with 114,000 miles on the clock however, the replacement turbo has only done around 80,000 miles. It was replaced last time for a cutting out due to an over boost, diagnosed as seized veins. Do you think any of your products will help?

Will this help with my VW Passat diesel turbo? The engine has done 214,000 miles. However the turbo, which has done around 80,000 miles cuts out under heavy load, I wondered if it was just clogged veins on the turbo. This is why it was replaced last time.

I bought a can of this for my 2006 Vauxhall Vectra sri cdti 150. The engine management light had illuminated and ran a test with a diagnostic tester which showed that the EGR valve needed replaced. I filled my tank after putting in the BG244 and ran it for a couple of weeks. I then ran the diagnostic test again and cleared the fault. The engine management light has stayed clear now for several weeks. This stuff has saved me costly garage repairs. I’ve now bought some for my wife’s and son’s cars. Highly recommended.

When using biofuel it is important that its fortified with the correct additive pack to protect against gelling, waxing, biological and chemical contamination. Regards.

I put the contents into a full tank of fuel and I must admit at first I did not think that it would do much as have tried other cleaners without any success ,anyway , after about 100 miles there was a signaficant improvement but now that I have done 385 miles the difference is massive . The idle now is so smooth and the acceleration is fantastic trouble is I am now using more petrol because I just like to go out for a drive

The oil has only just been changed and won’t be due at the service- although I understand its most ideal to put the can through then change the oil… talk about bad timing- although I could always do another oil change. What do you recommend? Car is a rotary engined Mazda RX-8.

Hi, it won’t affect the plugs and will be fine to use now. Regards, PE Team

Hi. Just a quick line to say i tryed this product as you advised, and the difference after using half of one tank full of fuel was incredible. More power and more mpg (between 15 and 20%) which is what i originaaly mentioned. What i would like to know now is, do i have to add any subsequent treatments or, just forget about it for about 12 months?. Thanks again.

Hi

I have a 325SE BMW. I had a diagnosis check done and told bank 1 and 2 oxygen sensors or Lambda needed to be looked at. I would start the car and at traffic lights it would be rough. After a while, once warm then drive okay and idle okay. Will the BG 44K help with this problem?
Please help.

Yes, if the sensors are faulty due to deposit build-up, the 44K will restore them. Regards, PE Team

Hi. I’ve got a 2 litre 02 Saab 93 petrol turbo. The vehicle is fully serviced and i do around 8000 miles per year. The fuel consumption seems a little low. Which of your products would you advise me to use.

I would use the BG44K as an initial treatment. Regards, PE Team

Bought a can for my 18month old 42000 mile Audi a3 1 .9 tdi which I’ve had about 5 months I have noticed an immediate improvement in acceleration and smoothness, the change in driving is amazing.

Missed out buying a used diesel xc70 4×4 Volvo 32mpg and left with a petrol version of the samecar but running at 25 mpg. If I bought the petrolversion plus your 44k what would you l
think I could improve the mpg to? Rural driving

Hi, it is difficult to say. It really depends on what the genuine MPG is, the type of driving you will do and whether there is any reduction as the result of fuel system and carbon deposits.

also, is it safe to use millers exomax. e.g. if i used bg244 once a year when i do my service, then also use millers between that time.

Yes, no problem, PE Team

Ok… In a nutshell.. if u have a older car.. mines is 11 yr old then this is the stuff to use if its not running as it should. after 8 mile in my full tank ive noticed better acceleration, more power with less push on accelerator. quicker autogear changes,quieter engine. also like to add that the smoke ive had coming from exaust for last 3 month (not head gasket or anything like that just smoke) has vanished. i was hesitant about this product as i always am but ordered anyway.

Hey, just got a can of this stuff and can’t wait to use it. Any advice on what amount to put in a 1.4 ford fiesta zetec? 45 litres I think.

Hi Tom, it is perfectly safe to use the full bottle.

Can you tell me how this product would clean the back of the inlet valves inside the inlet port on a direct injection engine like the Mini Cooper S? I have a Mini Cooper S which is prone to this problem.

Hi, the back of the inlet valves is the most difficult area to clean as they are generally out of reach of system carbon removers. However, we are testing a new product for this by Archoil.

Hi, would this product be suitable for all diesels? I drive a BMW 320d E90 and my wife has a Mazda 5 TD 143 bhp. Both are 2006 models.

Many thanks.

Hi, yes its fine for all diesel engines.

Hi, I’ve just taken my car to the garage after noticing the car vibrating violently @~1200rpm and have been told that I need to replace the EGR Valve which will cost £285. It is a 2.2L Vauxhall Astra MK4 Coupe Bertone and am told this is a very common problem with the Z22SE engine.

Would this cleaner work on this part which I’m assuming is blocked? and save me all that money.

Thanks

Richard

Hi Richard, If the EGR is completely blocked then AR6400 will struggle. It would be best to remove the EGR and related pipe work and clean it by hand. Then use AR6400 afterwards to remove any remaining carbon from the system.

i have a v8 petrol rangerover,carbon has blocked a oil gallery thus causeing a top end engine tapping.will your product sort out this problem or another of your products.please advise .thank you,kind regards,dave.

Hi Dave, I would recommend AR6400 for the fuel to remove all carbon build-up but for the oil gallery blockage you will require BG Quick Clean (engine flush), to use imemdiately before a fresh oil change.
