Würth Diesel Injection Cleaner is a hydrocarbon-based additive designed to clean and protect all common passenger car and truck diesel engines. It effectively dissolves and removes deposits from injection pumps, nozzles, and combustion chambers, restoring precise fuel atomisation and efficient combustion.
Corrosion Protection and Cetane Boost
The additive not only improves engine performance, but also binds and neutralises acidic condensation water that can accumulate in diesel systems. This provides long-term corrosion protection for sensitive components. Additionally, it boosts the cetane number of diesel fuel, helping reduce knocking tendencies and ensuring quieter, smoother operation.
When to Use
After repairs or maintenance on the injection system or engine.
After tuning work.
In case of starting difficulties or reduced performance.

Application Instructions
Ensure the fuel tank has the correct volume of diesel before dosing.
Add the additive directly into the diesel fuel tank. 300ml treats 30-50 litres of diesel. 1000ml treats up to 200 litres of diesel.
Drive normally to allow the cleaner to circulate through the entire system.
Usage Notes
Safe for all diesel injection systems, including common rail and pump/nozzle technology.
Recommended for regular preventative use, especially after repairs.
