Description
Enhanced Ignition and Performance
Würth Diesel Additive Cetane Booster is a hydrocarbon-based fuel additive formulated to raise the cetane number of diesel fuel. By improving ignition quality, it reduces the ignition delay phase and ensures more controlled, efficient combustion.
Optimised Combustion Efficiency
With a higher cetane rating, diesel fuel ignites more readily under compression, resulting in:
- Cleaner combustion with fewer deposits.
- Lower fuel consumption due to improved burn efficiency.
- Reduced engine noise, especially noticeable during idling and cold starts.
Improved Cold Start and Emission Performance
The cetane booster helps engines achieve quicker, smoother starts in cold conditions, while reducing white smoke, unburnt hydrocarbons, and other pollutants in the exhaust stream.
Practical and Reliable
Packaged in a 300ml container, the additive is easy to dose directly into the fuel tank. It is suitable for all diesel vehicles, from passenger cars to commercial trucks.
