Are Fuel Additives Safe?
by Andy Published on Wednesday, March 10th, 2010
Due to an increasing number of inquiries concerning fuel additive safety and vehicle manufacturers’ propaganda, I updated this article. Below is V2.0.
Are fuel system cleaners and fuel additives safe for my engine?
This is a question I am asked all too often, and I would like to put your mind at rest from the outset. From all my experience and testing, I have yet to find a commercial fuel-based engine cleaning product that has resulted in any form of short, medium, or long-term damage to a fuel system or engine when used per the manufacturer’s instructions. Sure, many products are poor quality or don’t deliver as promised, but the main commercial ones I have tested are at least safe to use. This includes engines with superchargers, turbochargers, the latest particulate filters, and high-pressure fuel systems. There are rare stories of failures or issues, but in all cases I have examined, they resulted from an underlying problem unrelated to additive use.
Please note that this is not a license for you to put any rubbish in your fuel tank! I only recommend cleaners using effective and proven ingredients. Providing the recommended dosages are not seriously abused, the cleaners I recommend are no more dangerous than the fuel itself. Some forget how corrosive gasoline is!
So why do Bill, Joe, and Agnes on ABC automotive forum advise against the use of additives? Why do my main dealer and car manual insist on no fuel additives? Why is there a warning sticker near the filler cap?
Very simple:
Firstly, ignorance. In any life endeavor, knowledge is power; it always has been and always will be. Combine this with the fact that people feel compelled to help and contribute regardless if the help or contribution is good or poor. When knowledge is lacking the void is generally filled with incorrect (usually a reiteration of someone else’s opinion/beliefs) or fabricated information (nothing more than guessing). Thus, poor quality help or contribution then follows.
In this modern age, the internet forum has become the perfect platform for all to contribute, feel needed, take on the role of “expert,” and help others. Some advice is good, and some are poor. Unfortunately with fuel additives, some are falling for the negative PR, parroting what someone else has misunderstood/misquoted or just second guessing.
Please note that this article is about the safety of additive use, not efficacy. I’m sure many are aggrieved with some additives’ performance and spurious claims, but that is a different conversation for another day.
Let’s look at this in more detail and help fill that void. Do you know the difference between standard and premium pump diesel fuels? Additional detergent package (usually DW-10 tested) and 2- Ethylhexyl Nitrate (2-EHN) cetane booster – that’s all. 2-EHN is the worldwide standard for raising cetane. DW-10 is the primary injector dirty-up and clean-up test procedure for measuring the performance of diesel fuel detergent packages in Europe.
Now let’s examine a diesel conditioner I routinely recommend for some diesel applications – AR6900-D MAX
It contains:
Latest DW-10 proven detergent package
2-EHN
Ester diesel fuel system lubricant
Combustion catalyst
Water handling, dispersant, demulsifier, stabiliser and anti-corrosion pack.
All proven and tested functions.
What is meant by “proven”? Is it guaranteed to perform? No, guaranteed to perform AND safe to use. By proven, it means that it is ALSO no-harms tested! Reputable fuel conditioners use no-harms tested ingredients. These ingredients and functions go through rigorous tests to ensure they are safe for the intended application.
As demonstrated above, some of what you find in diesel conditioners are already in premium fuels, except with additives; you pay less and get much more for your money. Every premium pump diesel uses 2-EHN for cetane index increase. Most diesel fuel conditioners use 2-EHN, too, as the primary ingredient!
Many diesel conditioners, AR6900-D MAX, included were blended for and comply with EN 590 specification diesel fuel. In other words, EN 590 pump diesel + AR6900-D MAX is still EN 590 compliant. You are still using fuel the vehicle manufacturer has stipulated you must use for that engine. This makes it much more difficult for manufacturers to blame additive use as the cause of a running or mechanical issue, although some still do, given a chance.
They are many other products too: Wynns, STP, Millers Ecomax, Redex, Cataclean, Liqui moly, Forte, BG and so on. Although they vary in efficacy, none of them will harm the engine.
I accept that I am in the business of selling fuel additives and need to make a living. However, before you question my motives, please understand this. I spend many hours in any given week helping others, mainly over the telephone, to resolve vehicle performance or running difficulties. Some calls can easily last 15-30 minutes for a product on which my company may make £3. Furthermore, less than 50% of calls result in a sale because I make it very clear to the customer when I think an additive will not help or is of no value.
Sometimes there is a lot of negativity with additives because of a misunderstanding of the ACTUAL functions and benefits or the overt misselling compounded by ridiculous claims. There are correct circumstances for additive use and times when they are simply unnecessary. Again, this is a different subject for another day (See the do additives work article).
There is also the risk of not using additives. Ask one of the thousands of satisfied customers, not just ours) that have used quality cleaners to resolve running issues, warning lights, power loss, engine cutouts, etc. Ask them which is safer, fuel cleaner, or engine jumping into a limp-home mode during an overtake maneuver. A bit dramatic, I accept, but still valid.
There are now a good proportion of fuel systems and engines that are MORE at risk from not using a quality regular use fuel conditioner (or periodic system clean) or at least using premium fuel to help give the fuel system and emission control systems a fighting chance.
Not a single day goes by where I don’t receive a request for help from someone that doesn’t use additives, and now the fuel system, engine, turbo, EGR, DPF, or a combination of these are causing running difficulties. Not a single day.
So what about the Main Dealers?
This too, is very simple – draconian thinking and revenue protection. Unlike in the US and other parts of the world, manufacturers (fronted through their main dealers) have a vested interest in maintaining a “replace with new policy.” For example, suppose the main dealer plugs in their diagnostics computer and registers a faulty diesel fuel pump or faulty injectors. In that case, they must advise the customer that they require a new pump or injectors.
I have seen a bill for almost £3000 to supply and fit four new diesel injectors from one of our customers! The fact that injectors and pumps can be reconditioned or that a good quality cleaner will resolve the problem 80% of the time is irrelevant. Main dealers have little choice, and they risk falling out of favor with the manufacturer or worse, losing their franchise if they deviate from the “replace with new” policy. If you accidentally put a stain on the carpet, would you replace it without trying to clean it first?
Another reason is risk mitigation. Manufacturers and dealers are simply protecting themselves from customers that may foolishly put a harmful substance in the fuel tank, i.e., bleach (and I’m not joking) or putting fuel additives in with the oil or visa-versa. Hence, a straightforward “no additives” policy.
Last but not least, you’ll be surprised to learn that many manufacturers already use additives. That’s right, but only when it suits them. For example, a prominent European petrochemical company provided an aggressive fuel system cleaner to a well know European vehicle manufacturer because they were facing hundreds of thousands of potential warranty claims from carbon build-up on diesel fuel injectors. The additive was administered to all affected engines on a recall or during the next scheduled service, and customers were none the wiser.
So why is it different in other countries? Unlike in the UK, the US main dealers have a strong influence over the manufacturers. In many cases, the main dealer will call the shots. Unfortunately, the UK and the EU, in general, are a bit behind.
Fortunately, the law is on our side (one of the few advantages of being in the EU), and we are starting to witness a change with manufacturers and franchised dealers. It is doubtful that a dealer would even know you were using an additive unless you told them as it takes serious equipment to detect additives. You are at greater risk of a dealer refusing a warranty claim due to using contaminated (untreated) fuel than using an additive to fortify the fuel or clean the system.
I hope this helps clear up the matter for our customers. If you require any advice or help, please don’t hesitate to contact me, and a member of my team or I will be pleased to help.

Hi just acquired a scenic 1.5 diesel .seems to run ok . I jwould like to improve mpg Etc .what product would you reccomend
Hi, I would try AR9100 in with the oil and test both AR6200 and AR6800 to see which gives the you the best results. UPDATE: I would recommend the new AR6900-D Max.
I have a 12000miles 60reg jaguar XF 3.0 do is it safe to use BG224 at such less miles? The car informs me from time to time that it delivers: “Restricted Performance”
Big dilemma, please advise
Yes, it is safe to use.
I have a 2.0 tdi 140 audi a3 thats doing average 40mpg, and a bit of smoke under load. will AR6400-D or bg244 help?
Hi, yes they will if the MPG drop and smoke is the result of fuel system or combustion deposits. Read our article HERE http://www.fueltechexperts.com/content/132-do-fuel-oil-additives-really-work.html
Hi
I have a 2005 BMW X3 2L Diesel which has 35,000 miles on the clock. The check engine light (EML) has been coming on periodically. Dealership says it needs a de-coke. At £1500+ it seems a bit excessive for a car of this mileage (emissions test was fine).
Would one of your products clear the carbon build-up that may be causing the dashboard EML to come on and keep the deposits from getting any worse?
Cheers, Karen
Hi Karen, please call us and we’ll go through the options with you. Kind regards
Hi, it is impossible to advise if it will resolve the problem without inspecting the vehicle. AR6400-D will swiftly remove any deposits from the injectors but it can’t resolve any mechanical issues. If the injectors are worn or damaged then no chemical cleaner will help. It will not adversely affect the fuel filter. It doesn’t matter how much fuel is already in the tank when the product is added providing you top up with fuel on top. See our article HERE on adding additives to the tank. Kind regards.
Hi, we operate a JCB 60kva diesel generator (basically a truck engine) using red diesel, it runs for 8-10 hours per day. The built in fuel tank holds 300 Ltr and we refill this weekly from a 1000 Ltr bund, would we be better to add to the bund treating the 1000 ltr or put it into the built in tank. Which product would you recommend and how often should we use it.
Many thanks.
Lyndon
Hi, I would treat the tank with AR6200 or AR6800. Regards.
Hi, found your site this morning so please excuse any protocol errors,have just purchased my very first diesel and although fairly knowledgeable on engines I am concerned about the amount of noise from the 115000mile 2.0TDCI Ford Mondeo Engine, it’s performance surprised me enough to buy it, inside the car it’s quiet and very quick,have changed crankshaft damper/pulley, belt, tensioner and changed oil and filter twice but it still sounds like a bag of nails, it’s also a little lumpy on tickover, I was warned off putting any additives into the oil or fuel but have continually searched for more info on this and am convinced that a good quality additive would help and on finding your site am even more convinced that your products would help, please advise as to which products and where I could purchase. Many thanks,Robin
Hi Robin, AR6400-D to start with followed by regular use of AR6200. This will ensure the fuel system is clean. We have also had great results with AR9100 on that engine. However, I would make sure the EGR system is not blocked as this is a common problem on that engine. Regards.
Hi, I have a 1989 pajero 2.5 turbo intercooler with automatic transmission. Clock shows 200,000 Kms, runs ok, just thought I might treat it to some fuel additive. What’s your advice?
Hi, AR6200 if there are no running problems. Best regards.
Hi. I have a 2004 Mazda 2 diesel which has done 140,000 miles The local mechanic says it has a “chuffing injector” which sounds like a loud tickover and has quite an engine smell . Will using any of your products help Cheers.
Hi, it is unlikely that any chemical product will resolve the problem as a chufffing injector is a failure of the injector seal. The injector needs to be removed and the seal replaced. Best regards.
Hi, I have a Volvo XC60 2.4 5WD (45.000 km) and I am driving it in Ukraine, where there is many rumours(and evidence) about the low quality diesel. So far I don’t have any problemS; however, I would like to avoid any and tackle the issue preventively. Which product would you recommend and how? Thank you very much for your attention, D.
Hi, we have many conusmer and trade customers in exactly the same position. The most cost effective answer is Archoil AR6200 as this addresses and resolves all the potential shorfalls in fuel. It will lubricate, protect against biological and chemical contamination, remove water, improve the quality of combustion maximising the BTU of the fuel, reduce emissions, remove existng and prevent further fuel system or combustion deposits etc. Best regards.
Hi, I have a 2008 (58) plate Toyota Avensis 2.2D-4D T180, 75k miles which has been losing its acceleration recently and very slow in 1st and 2nd gears. AA man said the code read ‘DPF’ problems. I’ve tried Cataclean and JLM lubricants+25 mile motorway drive, still drives the same. Is it still worth trying your product or would you recommend another product or course of action ? Really appreciate your advice (and great website).
Thanks,
Kerry
Hi Kerry, I would first read our article here and then contact us direct for further advise. Regards.
hi.i have a citroen c4 1.6 hdi [92bhp] i have blue smoke on start up when the car has been stood for a while.i have done 95000miles on a o6 plate. is it safe to use on this engine.
Hi, yes it is safe to use. Regards, PE Team
Hi, yes it is safe to use. Regards.
Hi, i have a 2002 peugeot 206sw 2.0 hdi. Is it suitable for this engine? The car has poor mpg an is a little bit sluggish. Do you recommend tu use a can in a full tank or can be less diesel in it?
Thank you.
Regards,
Gabriel
Hi, yes it is suitable but you need to dilute it with a full tank of fuel. Kind regards.
Hi,
Im running a Toyota Hilux vigo 3L D4D (Diesel common rail) 2008 model. what is the best cleaner i should use. current mileage is 50,000KM.
Thanks.
Regards,
Chullaka.
Hi, AR6400-D for a fast clean. AR6200 to keep the system clean and protected. Best regards.
There seems to be a lack of clarity over the use of certain products about to be introduced. The ARCHOIL 9100, for example, is shown under ENGINE and MANUAL GEARBOX, however is it suitable for semi-automatic boxes such as those in petrol Smart cars? If not, what is suitable especially where engine and gearbox are lubricated by the same oil?
Thanks
Hi, unfortunately we do not recommend using friction reducing additives in areas where friction is required, such as: auto gearboxes and limited slip differentials. Regards.
Hi,
I have a bmw 535d with 150k miles runs fine except for a slight flutter / miss when on very light feathered throttle or cruise at around 2000 rpm nobody has found the problem!, I suspect a slightly blocked injector. Will your product be suitable?
Thanks
Hi, yes it is suitable. Regards.
I have a 2006 Citreon Picasso diesel with 76K mileage
Previous services have had additives for fuel and oil
Can you advise what additives I use in order to give smoothe running
Does the additives require any run in and will the additives help with emissions
Thanks
Hi, I would recommend the Archoil AR6400-D/AR6200/AR9100 service pack. Regards.
Hi Team, I have a Ford Tourneo 2.2 TDCI 130hp 2007 can i use your diesel treatment for this engine only our ford dealer says it does’nt recommend any additives. We have had a problem with the injector (we think blocked), keep jumping out breaking the retaining bolt. Yhanks Craig.
Our products are safe to use. Regards.
Re 102
Sorry its a diesel engine
Will your product reduce emissions?
Do I need to take the vehicle for a long run after any introduction of product
How often do I need to use the additive?
Thanks
I have a 06 Citroen with 75K on the clock and wonder what additive[s] I should use to enable efficiency and keep emissions within limits
Where can I purchase your product over the counter or is it just via internet?
Thanks
Hi, is it a petrol or diesel engine? Best regards.
Hi, Will it be ok to use in a 20008 focus diesel tdci with a diesel particular filter? have heard it may damage the pdf. Cheers.
Hi, none of our diesel fuel cleaners will harm the DPF. Regards.
Got an old banger with a Nissan 2.7D non turbo lump that’s done over 300,000 miles. It chugs along quite happily but does tend to send out clouds of black smoke when accelerating “hard”. Somehow it managed to pass MOT recently but it would be good to reduce smoke etc if possible. (though it does keep tail-hoggers away!) A 1:200 dose of 2 stroke oil has been added to help lubrication etc as this “cleaner” fuel isn’t good stuff for old engines (so I’m told).
Thinking of dosing with BG244 and going for an “Italian tune-up” to give the system a much needed clean – do you think this will help or should I go the whole hog and get the service kit (Oil etc was changed recently so would prefer not to have to do it again?!).
Hi, I would recommend Archoil AR6200 in with the fuel and AR9100 in with the oil. This will restore both the engine and fuel system. Best regards.
Hi, I would like to ask is it BG suitable for Toyota Yaris 4-D4 engine 65k?
Hi, yes its fine. Regards.
Hi,Thanks for fast delivery.But I want ask you.If I put 150ml BG248 in my fuel tank,is it alright?
Regards
Tomas
Hi, yes if its a small tank of around 50 litres. Regards.
I have a peugot 307cc 1.6 60k on the clock drives like i am pulling 1 ton weight behind me do you think 44k will help?
Hi, yes if the issue is the result of fuel system or combustion deposits. Regards.
Was having problems with my 2000 Jaguar S-Type 100,000 miles. Engine was running roughly, especially at start up. Faulty engine light came on. Added to fuel tank. Car runs like new again. Incredible results. Next time symptoms reappear, I will use again.
Hi
I have a Skoda Octavia 2001 144k on the clock, it’s been great until the last month or so when it has started coughing very occasionally (every 30 to 50 miles) while cruising. I’ve been warned by a friend whose mechanic cleaned up an old Rover engine once about cleaning up old engines because of the risk of losing compression by removing carbon deposits which had made up for the wear and tear, and therefore creating starting problems where there were previously none.
What is the risk of this with a 144k engine?
Thanks
Hi, it is a complete myth that removing carbon from modern engines will reduce compression (By modern we mean is the last 30-40 years.) Except in some very old engines (40+ years) and a handful of 2 stroke engines, carbon actually REDUCES compression because it forces the rings away from the bore. Removing the carbon thus restores compression. We use fuel system based carbon removers and professional engine flushes on all engines where compression is low (but not damaged). 95% of the time this restores lost compression. Kind regards.
My 56 Mazda 5 Sports 2.0 Diesel DPF light has come on. Will this product help the regeneration. Does it effect the warranty on your car. How often should it be used.
Hi Karen, yes it will. We also recommend a “spirited” drive to help create the necessary temperature to burn of deposits. Kind regards.
Hi, I have a 2006 Vauxhall vectra 1.9 CDTI (150) which has developed a problem recently of being quite smokey (white) on startup, tickover, and also a slight misfire. Mechanic done an injector check and reckons that injectors aren’t spraying evenly and would need to be checked and rectified. Other than the above mentioned problems, the car runs fine. Was wondering if a treatment of BG244 in the tank would help as it would be a less expensive remedy.
Hi, yes BG 244 will help with this. Kind regards.
HI, I have a 2005/55 peugoet 307 SW SE 136 HDI with 34,500 miles on the clock from new and my depolution light has come on and states depolution system faulty, there is no loss of power and the car is running ok, would BG244 be safe to use on my engine and would it help with this problem the computer has given me a fault code of P1435, P0409, P0490. Thanks
Hi, it is safe to use. Sorry, we can’t help you with the fault codes. Regards.
Hi, got a can of this and plan to use it soon. will i see ecessive black/grey smoke from the back when engine is using it or should it be fine? using it in a Alfa 159 1.9 JDTM
Hi, it is unlikely you will see any black smoke. If anything it should reduce. Regards.
I have a Mazda 6 Sport diesel with 134,000 on the clock. The DPF warning light has just started flashing. Will BG244 help clear out the build up of carbon?
Hi David, yes it will help or we will refund you in full. Regards.
Hi,
I have just come across your product BG244 and I want to give it a try. Trouble is, I have just filled-up and used one of the off-the-shelf additives (Wynn’s I think). I have about 3/4 of a tank left, will I have to wait until I fill-up again to use BG244 or can it be put in at the same time as the other stuff?
Thanks.
Hi, you will need to consume all of the Wynns cleaner first. Regards.
Hi, one of my most reliable lorry’s has over 500’000km on the clock. What would be the best product to add, or at this mileage am I flogging a dead horse. Regards Martin
Hi Martin, the BG Diesel Service Pack will help restore that engine. Contact us for further info. Regards
Hi,
I have a BMW 2.0d X3 and the nice people at the main dealer want to charge me £2500 for a decoke to fix the stuttering at 2k/rpm. Will this stuff do the same thing. And is it safe to use on an X3.
And where can I buy it from.
Thanks
Hi, a friend has a 2002 vauxhall vectra 2.0 di, and it has just developed a fault where, when warm, will rev up and down when on a steady throttle position, and bring the engine light on, and cuts out. The engine light goes out again though almost immediately. Would bg244 eliminate this, or is it a major injection pump problem? Thanks
Neil
Hi, it is impossible to diagnose without inspecting the vehicle. Please call us to discuss further. Regards.
i have a 2006 audi 2.0 litre TFSI. Which product do you recommend i use and would it be safe. The millage is currently 57,000.
Hi, AR6400 and yes it is completely safe. Regards.
I have a bentley turbo r 1993 with 95000 miles on clock.It runs fine but I wondered if one of your products would be useful in cleaning up the engine.Any advise is good and where do i buy please. Thankyou
Hi, yes, it would benefit from a clean with that mileage. I would recommend AR6400. Regards.
Hi,
I have a Volvo V40 with the mitsubishi 1834cc GDi engine. It is very sluggish and almost non responsive around 2000rpm. Clock reads 167,000. I wish to know if this product will be ok to use on a Gasoline Direct Injection engine?
Thanks
Hi, yes it is perfectly safe to use. Regards.
Hello I am a dumb blonde with an 57 plate Jaguar S Type Diesel auto, having lots of trouble with fault codes showing “restricted performance” and Parkbrake fault, hence lots of expensive bills. Can you tell me what I need to do, I need an idots guide please.
Hi Eileen, please call us and we will run through the options with you. Regards.
Hello
I have a 57 reg BMW 118d series, will this treatment be ok for this car?
Hi, Yes its fine. Regards.
hi
is it ok for using in audi s6 v10
no problems but after 51k maybe it could do with a “clean”?
Also will this help/ affect mpg?
thanks
Hi, yes it is. Regards.
I’ve just used in my A4 2.0TDi S Line Quattro and the improvements werer almost immediate, namely cleaner response, hardly noticeablke turbo kick but more importantly an improvement from around 34 mpg to over 40 on most runs
Needless to say I will use this stuff regularly
Hi guys…have just bought a 2008 ford mondeo 2.0tdci edge which has 37,000 on the clock…which product will be best suited to my needs as I want to keep my car carbon free….cheers….
Hi, I would recommend BG244 as an initial treatment. Regards, PE Team
Hi, I would recommend BG244 as an initial treatment. Regards.
Does BG 244 have any cleaning effect on Turbo’s or Cats. I have used it about 4 tank fulls ago on my Diesel S-Type noticed an improvement in performance but also want to ensure my Cat’s and Turbo’s are clean. What do you recommend please?
Many thanks
Graham
I drive a Peugeot 3062.0 HDi with a Bosch fuelling system and have heard that Bosch recommend not using any fuel additives as they can damage the seals in the fuel pump. Is BG244 safe to use with my engine and fuel supply system or is it true what Bosch say?
Thanks Gareth
Hi Gareth. None of the products we supply will damage any seals in the fuel pump. Any such response from a manufacturer is a standard one and its aim is to 1. help protect the revenue of its dealers and 2. eliminate any potential risk of damage and respective litigation from customers puting harmful substances through the fuel system. It only takes one idiot…..Regards, PE Team
Hi, Can you tell me if it’s ok to use BG244 on a Land Rover Discovery TD5 (110k). Just a bit wary about LR fault codes which tell you to “go straight to Gaol (sorry-Main Dealer)”
No actual problems to correct, just want to keep it that way
Thanks
Ian
Hi, yes, absolutely fine. Regards PE Team
I had just failed my emissions test with my Peugeot Partner 1.6HDi. I was encouraged by the MOT Testing Station to purchase a can of the BG44K. Drove around town and a few miles of motorway(10 in total) returned to Testing Station and the vehicle had greatly improved emission figures enabling it to pass the MOT. Keep up the good work!
I have a renault megane II 1.9DCI and i have been told that i need to clean the injectors as i am getting a check injection fault which 1 should i use and will this help?
Thanks
Tariq
Hi, yes, if there are deposits on the fuel injectors then this will resolve it. Regards, PE Team
Hi is BG244 safe to use in a Mercedes 220 CDI engine?
Regards
Bob
Hi Bob, absolutely
Hi
I have a van that intermintly shows up the fault code
EGR valve stuck
Can this help free / clean it up ?
Hi, yes it will help providing it isn’t fully blocked. We would always advise cleaning the EGR system manually first. Regards, PE Team
Hi,
Will this decoke the sticking VNT vanes on a turbo.
Would keeping the vehicle under high load and rpm clean better if it does.
Cheers,
Mick
Hi Mick, it will help but as you have indicated, maintaining a higher RPM to increase the temperature of the post combustion components will help even further. Regards, PE Team
Can i use this in my jag x type 2.0 sport, its done 94k and seems to stutter when cruising around 2000rpm ?
Hi, absolutely. PE Team
any info well help
stevie
re have just put in BG244 in my saab 95 est 2,2tdi and filled tank 65 litres is this ok?and is it better to do short or long trips,is car speed of any consequence to enable BG244 to get through system any quicker? (this may be a daft question)lol
just used BG244 in my peugeot partner van (99 model 112000 mls) was slightly sluggish, now runs like new. smooth tickover, better acceleration, now better economy. have just put it into my audi A6 tdi quattro. if i have the same results i will be chuffed too bits. this product really works. highly recommended.
Hi, i used your BG244 in my Ford Mondeo TDCI last year and it done an excellent job. Since then i have gone over to using biodiesel, i was wondering if this is compatable and will it have the same effect. Thanks Lawrence.
Yes, it is compatible. Regards, PE Team
Afternoon, not very good with cars and therefore seek your guidance. I have a BMW 220d with 50k on the clock.
What will I require to “clean” the engine?
Hi, I would recommend the AR6400-D for that engine.
Regards,
PE Team
Hi is it advisable to change the engine oil after using any of your fuel additives,thanks.
Hi, only if you suspect that the engine is worn and/or compression is low.
Regards, PE Team
I’ve got a 2.8CRD with just 14,000 ml. Would this treatment be suitable at this milage or should I wait until I’ve done more than 20K to notice a difference.
Also I’ve read that adding fuel additives at every fill with higher cetene will improve combustion and produce smoother performance. Do you supply a product such as this ?
Hi, there will be deposit buildup even with only 14k but it is always difficult to determine what difference you will feel as we have witnessed huge changes on engines with less than 5K miles and little difference on engines with over 50k. However, the product will have removed all deposits and carbon build-up regardless. I would recommend AR6200 or AR6800 following on from AR6400-D as it will improve cetane (and combustion) but more importantly will help prevent future deposit formation.
Regards,
PE Team
Where can I buy this product? How much is need for a 40 gallon tank of diesel in a boat?
Will it stop excess smoke when starting?
Hi Stuart, I would recommend a full bottle of AR6400-D to treat the full 40 litres, It will stop the excess smoking or I will refund your money in full.

I need to know if it is able to be used in a motorcycle.
Yes, but you will only require between 1/4 and 1/3 of a can to treat a full tank of fuel.

Tried BG244 in my Focus 1.8 TDCI 2005 which was stuttering at low revs and on cold mornings, it is now running good as new. Great product, recommended.
Very enlightening and straight talking review and I will be trying in my Fiat 500 1.3MJT. One question, do you consider that it will improve the efficiency of the DPF as mine is regularly showing the warning message “DPF filter clogged” despite me making regular trips of over 30miles at a steady 65-70mph.
Hi Tony, yes it will as the active PEA chemistry is still cleaning post combustion in the exhaust gases.
