DIC - Diesel Injector Cleaner is a once only treatment to remove harmful deposits in the fuel pump and injectors of diesel engines. Added directly to the tank at the rate of 100ml per 100 litres (1000ppm) of fuel. DIC cleans fuel line and injector deposits providing a cleaner, easier starting engine. DIC reduces emissions, improves fuel consumption and present smoke from exhausts.
If your engine is smoking we recommend you use DIC before calling an engineer to remove injectors etc. Smoking is often due to gumming and lacquering of fuel components which develop over time or from using degraded fuel and will be a lot more cost effective than removing injectors unnecessarily.
Having cleaned the system with DIC we recommend you use Diesel Fuel Complete to keep it clean.
