Application & Instructions

Würth Diesel Performance Improver is designed for straightforward application directly into the diesel fuel tank.

Check Compatibility: Confirm the vehicle and fuel system are suitable for the additive.
Check Fuel Quantity: Ensure the fuel tank contains at least 10 litres of diesel.
Add the Treatment: Pour the entire contents of the 300ml can directly into the diesel fuel tank.
Observe the Dosage: One 300ml can treats up to 70 litres of diesel fuel.
Operate Normally: Use the vehicle as normal, allowing the additive to circulate through the fuel system.
Repeat as Recommended: Apply approximately every 2,000km or as directed following suitable engine or injection system repairs.

Important: Follow the current product label and manufacturer’s technical instructions. Do not exceed the recommended dosage.

Diesel Injector Protection & Deposit Prevention

Diesel injection systems rely on precise fuel delivery to maintain efficient combustion and consistent engine operation.

Deposits in fuel injection components and combustion chambers can interfere with the intended performance of the engine.

Würth Diesel Performance Improver is formulated to help prevent these deposits from forming while supporting the lubrication of fuel system components.

Its protective properties make it suitable for preventative maintenance, particularly in modern diesel engines with high-pressure injection technology.

Important: This additive is not a substitute for mechanical repairs, professional injector servicing or the correction of existing engine faults.

Improved Lubrication for Low-Sulphur Diesel Fuels

Modern diesel fuels are formulated to meet strict emissions and fuel quality requirements.

Würth Diesel Performance Improver helps support the lubricating properties of diesel fuel, reducing unnecessary friction in compatible fuel system components.

This can be particularly beneficial for precision-engineered diesel injection systems that rely on adequate fuel lubrication during normal operation.

Regular preventative treatment, when used as recommended, helps support long-term fuel system maintenance.
