## Overview

STP Diesel High Mileage Injector Cleaner is a concentrated 200ml formula designed to clean and protect diesel engines with high mileage. It restores power and smooths rough idling by removing carbon deposits and conditioning the entire fuel delivery system, improving fuel economy and engine responsiveness for up to 300 miles. Made in the UK, this trusted additive is easy to apply and ideal for maintaining optimal diesel engine performance.

## Description

From the manufacturer STP = Scientifically Treated Petroleum Build up - Intake Valves Deposits on the intake valves can restrict or change the flow of air/fuel mixture into the combustion chamber When you shut off the engine, fuel that remains on the intake valves can polymerize into a hard carbon deposit or form a sticky gum Oil leaks past the valves seals and can contribute to deposits on the back of the intake valves Exhaust gas recirculation, which is a mechanism used in engines to reduce emissions, can cause soot and other combustion by-products to deposit onto the valves Fuel Additives For over 60 years, and for more miles than anyone can count, STP has been one of the most trusted names in automotive care. Car enthusiasts, “Do-it-Yourselfers” and professional racers rely on STP oil additives, fuel additives and brake and power steering fluids to keep their vehicles running better longer Due to 'Long Life' servicing intervals being stretched further, many vehicles face a build up of deposits that could have major implications on engine performance So why Use a Fuel additive? Additives are a relevant part of engine maintenance regime Car manufacturers recognise that “Clean engines = Better performance” Additives help keep vehicles running well, extends reliability, less likely to break down Build up of carbon deposits can occur within 4,000 miles, no matter how new or old the car is Build up - Injector Cleaners Clean fuel injectors are critical to vehicle performance Deposits can affect spray pattern and flow rate The spray pattern of fuel affects air/fuel mixing Fuel may be in droplets that don’t evaporate Fuel may stick to the intake port and not be drawn into the combustion chamber Clogging affects amount of fuel delivered, which results in inaccurate air/fuel blend

Review: Good product and gives great result - Did the job perfectly. I have only used one of the bottles so far. My diesel engine started running a bit rough and felt like she might cut out when I was stationary at junctions. She's an old Kia Sorento. I figured before I booked her in for exploratory work, I'd add the bottle to my next tank of diesel and it worked. One day, when I put my foot down hard, I could see a puff of black smoke come out of the back of the car (after I'd used this additive) and have not had a problem since. I think it cleared whatever gunk was in the fuel system. I'll be using the second bottle in about 6 months time. I used the Diesel Injector cleaner first. I'll use the Diesel System cleaner next. Good price and super fast delivery. I've only used the injector cleaner so far and driven around 100 miles but the fuel economy has definitely increased and the engine noise has gotten quieter so i'm happy to recommend.
Review: Excellent product stop here solved my high mileage Land Rover in few hours - Yes I thought I’m going to give them a try this time and I diverted to this product and I’m glad I did it has got to work and a huge difference in what 10 miles I started noticing the acceleration levelled in response to my foot instead of struggling I now after a week have a vehicle that runs pulls good and is responsive again easy to use a cheap way to solve further headaches if left I will be using every 2900 miles as I have high mileage

### ⭐⭐⭐⭐ It works
*by S***E on 1 July 2026*

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.
