We have talked on here before about Diesel engines and the need to give them a good ragging occassionally to clean them out. As a careful driver who pays for his own fuel and intends keeping his car for several years - i am a bit uncomfortable with ragging the car, so is there a fuel additive/cleaner i can use to do this for me.

Colleagues have recommended something called Forte to do this and have dismissed the usual redex stuff as been useless.

Has anybody got experience or advice on this?..... does it work?......or is a ragging the only answer?.

we only recomend Forte products we use the oil flush on every service we do and recomend that diesel owners use a diesel fuel system treatment once a year this removed carbon deposits from the valves and head and cleans injector nozzels


on a personal note last year i bought a 175k vivaro van it was running bad when i picked it up from newcastle i put three cans of treatment in the full tank (very strong mix) by the time i got back to southampton it was running better because it was going to be my transport at weekends i took the head off i was amazed the head and valves looed like new there was no carbon in the head or valves the injectors were clean at the nozzel but internaly they were u/s but hey you cant expect a liquid product to rebuild knackerd seals



we have been using forte for the last 12 years and have never had any issues make sure you get the correct product they do lots of diffrent ones from fuel system treatments to specialist injector cleaners oil additives look on their web site for the full range

i think ive had a bit of experience with diesel engines ,carbon and the subsequent residue of a tar like substance that builds up when a diesel engine is left idling for an extended period of time it is also present around the combustion chamber and valve stems if the engine has not been in a "working hard" mode!! it builds up and gets everything sticky this in turn gives all manner of problems the most common is with the type of turbocharger the soul has on its crdi power unit the vvti (variable vane turbocharger) if you go on turbo technics website they "qoute" say the problem is worst when the " vehicle is used for short journeys when the engine does not get up to full operating temperature" this means that if the vehicle isnt being given a thorough warm up and subsequent hard working you are at risk , this has always been a problem but not so much so if the vehicle is used a lot and gives reasonable mpg s you can afford a regular caning, however if you are like the rest of us and can physically see the needle drop as you drive in a brisk manner you aint so inclined to give it its head so often, this however is counter productive so the only real answer is warm her up and drive through the rev range regularly you wont hurt her at all in fact she will thank you for it , ive pulled diesels apart and never had one fail through overwork its usually a "catastrophic failure" due to neglect or lack of maintenance , however its not all bad you can use the cleaners etc and get some benefits but most modern diesel fuels have the cleaner in anyway so if you purchase say bp or esso etc you will already be adddig the cleaners, the golden rule is always warm up thouroughly before asking the engine to work, this is must as if it isnt done major distortion of the engine parts can take place as the engine is worked whilst not up to temp.

When i drive to leeds every couple of months..... cruising at 70-80mph for about an hour and half (2400-2800 revs)...... is that classed as a good enough "clean out"?

Hi Tempest. I think the term 'Ragging it' is a bit extreme. I think rags are sheets torn to pieces, and you do not want to do that to your engine. Brisk driving is a better term. There is a red line on your tacho set by the manufacturer. Providing you do not constantly travel over that line, your engine should be fine. I occasionally give the pedal a good push past the 'click' for some brisk acceleration, (2nd, 3rd, & 4th gears). If you have not done it for a while you will see some black smoke for a short period. This is cleaning it a bit. Not to be confused with black smoke when trying to accelerate in too high a gear when all that means is that you are flooding the engine with diesel and chucking out unburned fuel. I am not an advocate of additives, unless you drive like a snail everywhere. There are quite a few additives in good fuel anyway. If you bumble around everywhere then by all means stick some cleaner in the engine, but not too often as you can start to wash any lubricants off the bores, causing problems of its own. Think, how many cars have you owned and how often have you had trouble with the engine, and been told it was because you have not used additives?
Marketing is good for sales!!
I wonder how many London Black Cabs with 200k miles have additives in them.

as an aside i have given up trying to get hypermiles out of the soul and just drive it as normal because a good consumption figure just isnt forthcoming so i am now resigned to it i guess , it will be interesting to see how well the new ix 20 by hyundai sells its using the 1.4 engine that was in the venga (yes the one that was and is i believe a little bit of a challenge)its published mpg as 67.4 !! its not that different in engine size and its aimed at the mpv market so a few soul owners i think will drift across if the fuel figures are correct as a few on this forum im sure bought with a degree of fuel consumption in mind.

My Soul 2 CRD averages around the 50mpg no matter how I drive. Not to say that if I drove up and down the motorway at 80mph everyday i would get that, but it is better than the 32mpg I was getting out of my Seat Altea 1.6 petrol.

When the Soul was 12k serviced the garage did use an additive to flush the engine and injection system(For free which I was amazed at) I don't know if it did any good but I am sure it would do no harm.I have always driven the soul hard ,the pedal "click" is normally used all the time in driving which may account for the mpg figures I get which on todays fillup at the new robbing prices was 48mpg.The car is worked hard with a lot of motorway driving and it should have 16k on the clock on it's first birthday on the 2nd of March.My motorway driving shall we say is at fairly high revs however the soul seems to thrive on it ,apart from the mpg figures ,so I am resigned to the fact that my mpg will be in the high 40s hopefully.The only thing I am careful is that until the engine reaches the operating temperture it does not work hard at all.In all the years I have been driving I have never had engine problems on any of my cars.

When I worked for a Jaguar dealership they always put in some Forte before draining the engine oil. They charged over £10 for this flushing oil making a good profit. My Soul was serviced by a dealership OWNED by Kia. No additives were put in the engine. Or at least I was not charged for any, or told that any had been used. So if they are not putting it in then maybe it is not required. Or maybe they are hoping that by the time the warranty is up, I will be due a new engine at my cost!! I think not. In over 40 years of driving and racing cars I have never used an additive, and apart from the crown coming off the top of one piston at Silverstone, I have never had an engine failure. Fingers crossed.

I calculated that since I started driving I have covered 2.25 million miles and I have had no problems with any engines.I am sure that they said it was Forte they used but as they did not charge me I just accepted the fact that they had done it, it was done without my knowledge anyway,it was only mentioned after the service.

Thats an interesting coincidence. My other car is a Seat Altea 1.6 petrol. When my dad owned it, it did about 23mpg!!!....and then gradually improved to 28mpg and up to 32mpg on a run when it was run in and from then on. I get 37 to 39mpg out of it general running about, compared to my Diesel Soul at 46 to 51 mpg on the same use. I can usually match the manufacturers fuel figures with all my cars....except the Soul. (i once managed 69mpg average on a run through wales in a petrol 903cc Fiat Uno in 1983)

On a good run the Altea would probably get 35+mpg, but generally the 32 was about right. Funny about manufacturers figures, my 2ltr A4 140bhp Avant was listed as combined at 48mpg and that is what I got out of it. To be honest I have not looked at what Kia list as their combined mpg I bought it for the ugly(?) looks. I will go to their web site and have a look.

Come on Tempest it's easy to get 61.4 mpg out of the soul all you need is a very long downhill stretch with the wind behind you no problems.
