Millers Diesel Injector Cleaner - 250ml

Absolutely brilliant product, product works as described and quality of product is excellent.

Used this in my injectors, one bottle to about 80 litres of diesel and it cleaned them as it said it would. The bottle instructions tell you that you need to do about 200 miles before it starts cleaning the injectors. I noticed this, didnt feel like it did much at first but after several days of driving, I felt the injectors suddenly spring into life as when I put my foot down I could feel the difference. I bought two bottles and treated the second tank the same way. No doubt it will need doing again at some stage in the future but it cleared alot of the diagnostic codes I was getting regarding cylinder imbalances which was been caused by the clogged injectors. This was done about 6 weeks ago and so far no fault codes relating to this problem have come back. Def need to do it once in a while if you put the cheaper diesel in from the supermarket chain filling stations.. Highly recommended if you are having these problems, at least give it a try first way cheaper than replacing your injectors which can cost 100's.

Used this because van had slight misfire and spanner sign coming on at 50 mph Put the whole bottle in 50 Lts of diesels within 300 miles van performing much better still a very slight misfire at idle but spanner light no longer comes on would recommend based on my experience.

Had very worrying knocking coming from 2l TDI (Octavia mk3). Symptompts indicated problem with injectors. Decided to try this before taking it to a garage. So far so good. Knocking is gone, engine runs quiter altogether and economy seems to have improved by 2-3 mpgs. Just bought a second bottle. Still, I would want to know what effect occasional use has on long term health of the engine.

does the job neede more than one

I switched to millers a few years ago, and all of their products are extremely high quality. This is no exception, fantastic additive for clearing carbon

My Citroen Nemo van would lose power & smoke heavily every couple of weeks or so. I used the additive in a tank of fuel and drove it for a couple of weeks & the smoking & loss of power have not occurred since. I’m so impressed I’ve ordered a petrol additive for my Jaguar.

Not sure it did anything but it’s a millers product so obviously I’ll buy more to see 🙃
