## Overview

Wynn's Diesel Injector Cleaner (325ml) is a high-performance additive designed to restore diesel engine efficiency by removing carbon deposits and contaminants from the entire fuel system. It improves fuel atomization, reduces engine knocking and black smoke emissions, and protects injectors and pumps from wear. Compatible with all modern diesel after-treatment systems, it ensures smoother starts, enhanced combustion, and longer engine life, making it an essential maintenance product for professional-grade diesel performance.

## Description

This diesel injector cleaner offers a powerful and complete solution for maintaining and restoring the efficiency of diesel engines. Engineered with high-performance cleaning agents, it targets the entire fuel system—from injectors and fuel pumps to the combustion chamber—removing carbon deposits, varnish, and other contaminants that accumulate over time. These residues can significantly degrade injector spray patterns, reduce combustion efficiency, and lead to increased fuel consumption and emissions. By eliminating such build-ups, this cleaner restores optimal injector function, ensuring precise fuel atomisation and a more complete and efficient burn. Not only does it clean, but it also improves the ignition quality of diesel fuel. This enhancement results in smoother engine operation, more reliable starts, and a noticeable reduction in diesel knocking noises. Enhanced combustion performance also leads to lower black exhaust smoke emissions, supporting cleaner air and improved engine compliance with modern emission standards. Additionally, the formulation includes lubricating properties that protect critical components like injectors and the fuel pump from premature wear and tear, extending their service life and maintaining smooth fuel delivery. Safe for use with all modern diesel after-treatment systems—including EGR, Turbo, DPF, and SCR—this product is compatible with even the most advanced diesel engines without compromising sensitive components. It offers dependable results without the use of metallic or abrasive compounds, making it a smart choice for long-term engine care. Designed for regular maintenance, it ensures engines remain efficient, powerful, and less prone to costly fuel system repairs or performance losses.

## Features

- Harmful to aquatic life with long lasting effects.
- May be fatal if swallowed and enters airways.
- Repeated exposure may cause skin dryness or cracking.
- ✅ CLEANS DIESEL INJECTORS AND RESTORES SPRAY PATTERN: Formulated with advanced cleaning agents, this diesel injector cleaner effectively removes built-up carbon deposits, varnish, and other contaminants that accumulate over time on fuel injectors. These residues can severely impact fuel atomisation and disrupt the injector spray pattern, leading to inefficient combustion and increased fuel consumption. By dissolving and removing these deposits, the product restores the precise spray needed for optimal engine performance.
- ✅ IMPROVES DIESEL FUEL IGNITION QUALITY AND COMBUSTION: Designed to enhance the combustion properties of diesel fuel, this additive works at the molecular level to improve cetane levels and promote a more complete burn during the ignition process. Improved ignition quality leads to more efficient engine performance, reduced engine noise, and enhanced acceleration. A cleaner and more efficient combustion process also helps in reducing unburned fuel residues, which are often responsible for increased emissions and incomplete power delivery.
- ✅ CLEANING AND LUBRICATING ACTION FOR THE ENTIRE FUEL SYSTEM: The dual cleaning and lubricating action of this formula ensures not only that contaminants are removed from the fuel system, but also that essential components like injectors and the fuel pump are protected from premature wear. Deposits that restrict fuel flow and impact injector function are effectively broken down, while friction-reducing agents coat metal surfaces to prevent scoring and degradation. This results in a longer lifespan for fuel system parts and improved efficiency throughout the engine's operation.
- ✅ REDUCES DIESEL ENGINE KNOCKING AND EXHAUST SMOKE: By addressing common issues such as injector fouling, uneven combustion, and poor spray patterns, this cleaner reduces the incidence of diesel engine knocking — also known as detonation or pinging. These noises are typically caused by premature combustion of the air-fuel mixture and can lead to increased mechanical stress and potential engine damage. The improved combustion quality not only eliminates knocking noises but also reduces the formation of black exhaust smoke, a typical by-product of incomplete combustion and excess fuel delivery.
- ✅ SAFE FOR USE WITH ALL MODERN AFTER-TREATMENT SYSTEMS: Compatible with a wide range of diesel after-treatment systems including EGR (Exhaust Gas Recirculation), Turbochargers, DPF (Diesel Particulate Filters), and SCR (Selective Catalytic Reduction) systems, this cleaner is formulated to deliver effective results without compromising critical engine components. Its composition avoids the use of metallic or ash-producing additives, ensuring that sensitive emissions-control devices remain protected and fully functional.
