Contamination in diesel engines caused by fuel quality

Transport companies operating internationally often encounter diesel fuel of lower quality. This contaminates the injectors and engine components of trucks, leading to increased fuel consumption, reduced performance, and more frequent breakdowns. Eurol Additive-S Diesel effectively and structurally addresses these issues.
Situation Description

An international transport company with a large fleet operating across Europe experienced issues related to diesel fuel quality in certain countries. The lower fuel quality caused severe contamination of injectors and engines. As a result, fuel consumption increased, engine performance declined, and the number of breakdowns rose significantly.
