STP Ultra 5 in 1 Diesel Fuel System Cleaner 400ml , Restores Power and Protects your Engine, Enhances Fuel Economy, Mechanical Car Cleaning Products, Concentrated Cleaning Formula, Made in the UK

I’ve been using the STP Ultra 5 in 1 Diesel Fuel System Cleaner in my car tuning and workshop business for a while now, and it’s been fantastic. I use it on everything from standard diesel vehicles to high-performance tuning projects, and it consistently delivers excellent results. This cleaner tackles multiple issues at once — it cleans injectors, removes carbon deposits, prevents corrosion, and improves overall fuel efficiency. I’ve noticed smoother running engines, reduced smoke, and more responsive performance after use. It’s also incredibly easy to use and works with every diesel vehicle I’ve tested. Compared to other fuel additives I’ve tried, this one really stands out for its reliability and effectiveness. It’s a small investment that pays off in better engine performance, longevity, and fewer maintenance issues. For any professional working with diesel vehicles — whether in tuning, repairs, or general maintenance — the STP Ultra 5 in 1 Diesel Fuel System Cleaner is an absolute

I’ve used this 4 times now on my 2008 Land Rover Discovery 3 (150k miles) Each time has quietened the injectors and made the engine overall more quiet and smoother, while increasing the power, efficiency and slightly increasing the MPG. I’ll be doing it a 5th time in a couple of thousand miles and will report again.

Seems to be okay, not noticed any improvement yet

Better than the description

used before many times great results for money Effective , compatible

I turned my car on and noticed the dreaded engine light. After a faulty EGR valve was diagnosed and replaced I thought all was fixed. A week later the engine light appeared again. After it was looked into further, my 4 year old 30k miles Diesel Mini was found to be blocked with carbon and my exhaust pressure sensor pipe was completely blocked, which was also what clogged up the EGR valve too. I always try and use the premium fuel and take it on long runs at high revs to clear everything out but this had obviously not worked. I researched for a while to compare different additives that would stop this problem from coming back and I finally chose STP ultra diesel system cleaner. It states it is a 5 in 1 and it helps to save fuel, restore peak performance, cleans deposits, reduces wear and inhibits corrosion. I waited until I needed to fill up my fuel and, before filling, poured the whole bottle into the tank to allow it to mix easily when the diesel was filled up. I then took my car for a trip to allow the cleaner to start working in the car although it doesn’t say that you need to do that. I haven’t had any further problems yet and that was a year ago now but it took 4 years for the problems of the carbon build up to show. The box states that you should add a bottle to the tank every 4000 miles so I am going to follow this and time will tell to see if it does what it says it will. I am hopeful as there are many positive online reviews and videos for this product. I am not waiting until I have a problem again and would rather be proactive in trying to stop deposits damaging my car. Hopefully the carbon will either be slowed down or even stopped and I will update this review if I have any further carbon problems with the car.

I normally use Wynns system 3 cleaner for the wife's 2014 S-Max and i have never had any issues. Decided to give this a try as it was a good price and read a lot of reviews stating it works wonders. With the Wynns product i would normally go to the petrol station and add the product just before filling the tank. I tried this with this product but could not get it to go into the tank. Ford's typically have a capless filler (no fuel cap just a flap that is pushed back by the nozzle during refuel) With the wynns product the bottle mimicked the fuelling nozzle and opened the flap. For some reason the STP product would not open the flap even though it looked similar to the wynns bottle. As a result most of the product went on the floor whilst i was trying to get it into the tank. I had to locate the adaptor to get what was left in the bottle into the tank. I will stick with the Wynns product in the future.

Put it in diesel tank, filled car with diesel, I felt car engine sounded better, got more mpg as a bonus.

Yakit tuketimi konusunda 0.3 litre civarinda katkisi var, ciddi boyutlarda olmasa da kabuk edilebilir duzeyde. Motorun devirlenmesi ve canliligi da artti. Uretici firma 6500 kilometrede bir 50-60 litrelik yakita takviye edilmesini tavsiye ediyor. İşe yaradigini soyleyebilirim.

Uso da parecchi anni questo multi pulitore e devo dire che è uno dei pochi prodotti di questo tipo che funziona veramente il mio motore diesel ha 170000 km e fa un pò di fumo solo se ci spingo forte e dopo i 3000 giri però bisogna usarlo costantemente io lo metto ogni 15000 usando anche il prodotto da aggiungere all'olio motore. STP è uno dei pochissimi produttori di additivi che li testa in pista prima di immetterli sul mercato!

Come da offerta d'acquisto. Prezzo concorrenziale. Consegna effettuata nei termini. Venendo all'aspetto "tecnico": non ho notato consumi inferiori (è anche vero che il clima è rigido e che tengo accesi plurimi accessori che fanno lievitare di per sé il consumo di carburante) né maggiore brillantezza (la mia vettura ha già 190 cavalli...). Confido nella pulizia e maggior lubrificazione di iniettori e altre parti meccaniche in movimento, di cui, ovviamente, non posso conoscere lo stato d'usura.

Fotografa bakıp ürünün yenilendiğini düşündüm. Ama alakası yok. Eski ambalajla geldi. Ürün zaten çok iyi bir ürün. Kullandığınızda aracınızın nefesinin açıldığını hissedeceksiniz. Rahat çalışma, vuruntu azalımı, ses azalması, yakıt düşmesi. 4 depoda bir mutlaka kullanırım. Aracımı 2013 te sıfır almıştım. Şuan 300 bin km de. Ne enǰektöre ne partikül filtresi nede motorumdam sorun yaşadım. Resmen aracın ömrünü uzatıyor. Ayrıca önemli uyarı; Dizel aracınız için opet, shell, total dışında başka bir yerden mazot almayın. Yoksa enjektörleriniz büyük bir masraf açabilir size.

ürünü ve diğer stp katkı ürünlerini yıllardır aracımda kullanmaktayım herhangi sorun olmayan araçlarımda önleyici olarak kullandığımdan faydası konusunda net bir şey söyleyemem ama zararı hiç bir şekilde olmadı, kanıtlayamam ama :) faydası olduğunuda düşünüyorum, stp ürünlerine amazon satıcılı olarak ulaşmak güzel inşallah devamını getirirler.
