Eurol Additive-S Flush is a mix of specially selected flush agents and Eurol Syngis additives. It is especially developed to flush and clean heavily polluted diesel engines before they are filled with fresh engine oil. The product does not contain lowviscous, volatile solvents, ensuring gaskets and seals are not harmed while flushing. Also, the danger of having low viscosity solvents dilute the fresh engine oil is avoided, ensuring maximum performance of the fresh engine oil. The Eurol Syngis additives which have been added to the Eurol Additive-S Flush give an added reserve lubrication when any remains of Eurol Additive-S Flsuh remain in the engine. It does not contain chlorinated paraffin or PTFE microplastics.
