Cataclean Diesel Fuel and Exhaust System Cleaner 500ml for DPF, Injectors and Valves

Poor performance, high emissions or DPF issues?
Carbon build-up inside the fuel and exhaust system is a common cause of reduced power, poor fuel economy and failed MOT emissions tests. This is especially common on diesel vehicles used for short journeys or stop-start driving.

Cataclean Diesel Fuel and Exhaust System Cleaner is a powerful treatment designed to tackle these problems at the source. Added directly to the fuel tank, it works through the system to break down carbon deposits and help restore proper engine and exhaust performance.

Why use Cataclean?

Over time, deposits can clog injectors, restrict airflow and reduce the efficiency of components such as the EGR valve and DPF. Cataclean helps clean these areas, supporting smoother running, improved fuel economy and reduced emissions.
