STP Diesel High Milage Injector Cleaner 200 ml, Cleans and Protects your Engine for 300 miles, Enhances Fuel Economy, Mechanical Car Cleaning Products, Concentrated Cleaning Formula, Made in the UK

Added this to my Ford Focus 1.6 Tdi with 140,000 miles on the clock after losing power going uphill and engine malfunction light coming on when accelerator pushed to floor. Added to half tank of diesel and all ok since. Used this before with same problem but added to full tank and took a while to rectify. Description on Amazon says protects for 300 miles but should read 3000. Engine malfunction suggests fuel filter fault but this is a quick temporary fix until car goes in for service.

It works

My Vauxhall has frequently DPF troubles. I used this once and felt the acceleration improved substantially. I thinks this works on the injector as said and will buy the system cleaner later to keep my car away from the warning DPF light.

I am skeptical of magic potions put in your fuel to make it run better, but I got into desperate situation where engine failed, and services were not available far too long to help fixing the problem. So I had to try alternative medicines 💊 and it worked like magic 🎩. At least it solved the problem for now and allows me to use the car unreservedly at this moment. The symptoms were lack of power, sounded like one or more cilinders misfire or even shut completly. I barelly could move, accelerating beyond 30 required considerable steady run, so getting on motorways was a bit intimidating. Things to know, it takes a bit of patience to get on to faster constant streaches of road and drive a bit at least because the fuel filter in your car holds about 1 liter of fuel and for this to start working one need to burn all the untreated fuel in filter and system after the tank. So be brave and patient let it work through. One other small thing to consider I have topped up half of tank premium diesel from shell to make the tank full, thinking that it also has some magic bits in it.

use this every 3-4 months, does what it says and i will keep using it.

Great product works well.👍👍

i had trouble in the mornings with hesitation and the feel like the van was choking itself up , friend of mine said probably your injectors , well i looked to see if it could possibly be something else more than the dreaded injectors , i saw that the filters sometimes can get caked with the poor quality diesel we use from supermarkets and this can indeed lead to blockage of injectors filters etc etc so i bought a bottle followed the instructions and waited , the first week nothing seemed to change and i thought and feared the worse , but read some other reviews and saw other people had tried a second bottle the next time the tank was near empty this time at the end of the second week the problems had gone, so i will now use a bottle every 3-5000 miles to flush through the system , obviously its not always going to work for everyone but if you have similar issues then for just over £5 a bottle its worth a try so i highly recommend it .

Didn’t really see a difference in how my car performed. Used in a high mileage golf GTD.

Ottimo la macchina va benissimo anche dopo 2000 km dall'utilizzo. Consigliato.

ok

Ürün çalışıyor. Sabahları titreşimli çalışıyordu araç büyük ölçüde düzeldi kullandıktan sonra.

Tja STP eben , Fehlerfreies Produkt

Aunque se equivocaron en el envío se solucionó rápidamente. El producto muy bien. Cuando lo puse en el depósito al los pocos kilómetros se notaba como el coche iba con más fluidez, más "alegría" teniendo en cuenta que son más de trescientos mil kilómetros.
