STP Diesel Particulate Filter Cleaner 200ml

Does what it says on the bottle

I have had problems with my DPF clogging up on my 2014 Nissan X trail Dci (T32). As the filter clogging up is not covered by the manufactures warranty, and having spent £187 to get it cleaned, I decided to use STP Particulate Filter cleaner regularly (I have used STP products previously) as it is quite inexpensive compared to some similar products. I have not had any further problems with the DPF over 10000 miles but it has also improved my MPG from approximately 48 MPG to 56 MPG on a 80 mile round trip on the M4. The car is also more responsive especially from standstill.

Not sure about it

I bought 3 bottles of this because I run a diesel and due to shorter trips I was getting error message "filter in danger of clogging". I added a bottle to a full tank as instructed but after using the car as usual I was still getting the warning. So as instructed I went for a thrash on the motorway for 30 mins. This cured the problem but it would have done so WITHOUT the additive. The question is will the additive keep the filter clear from now on? I am now back on refilling with diesel alone so lets see. It days use every 1800 miles. All I can say is try it but I can"t really recommend or not! Time will tell!Read full review

Got rid of my engine management fault light and made the car run a whole lot better too! Well worth buying.

I run an old diesel car and had been experiencing difficulty with the engine management light showing up on the dash. It turned out that the diesel particulate filter (CAT) in the exhaust system was clogged. After running a couple of bottles of STP DPF cleaner though the fuel system, not only has the annoying light on the dash gone out, but the car has more power as well as better fuel economy.Read full review

STP diesel particulate filter cleaner

I have used this additive for the last twelve months and and over that period there is a notable improvement, the engine runs smoother, easier and quieter there may also be a small increase in mpg one or two miles difficult to measure as most of my journeys are short certainly no increase.

STP - DPF cleaner

Appears to be good value for money if you get at least 1500 miles per bottle against the 1800 miles quoted. If this can keep the dpf from blocking up with soot whilst doing a fair amount of shorter journeys this will rate as exceptional value for money and I will be buying for the duration of the vehicle but only time will tell.
I am still expecting this to only assist the running of the vehicle on shorter journeys by way of the soot being burnt out of the dpf at lower temperature and prolong the useful life of the dpf. This will equate to a spend of approx £15 a year which when compared to the cost of a new dpf or even just the hassle of taking this off and getting it cleaned out appears like a win win situation :-) ThanksRead full review

Great value

I have used this item before and found it works well keeping the engine clean (injectors) my car has never failed the MOT test on emissions and as it is 15 years old thats good.

Does what it is designed to !

This product does exactly what it is claimed to do. After an expensive visit to a Toyota garage to find out why the Yaris had lost power I was informed that because of short journeys the dpf had sooted up. Since then every 2 months I add STP to the fuel tank and have never had any further problems.
Highly recommended.Read full review

Good brand, good price

A good brand at a good price I don't do high miles so this is excellent for keeping the filter clean.
I use this with every 2nd or 3rd fill of diesel

STP dpf

I have used dpf now for about 14 years,and I have never had any problems with my with my filter,it is a fabulous product,try it for yourself, you will see a big difference, well done STP.

A Good Product in my experience.

Engine management light started to display on the dashboard intermittently, OBDII code indicated it was an air flow fault, previous experience of this fault led me to believe it might a DPF or dirty fuel problem.
Since using the STP the fault has disappeared . I use it every 4th or 5th full tank of fuel.
