The latest generation petrol contains a BIO percentage (Directive 2009/30 / EC - UNI EN 590 - UNI EN 228) with minimum percentages of 8% on the volume. There are several factors that contribute to the deterioration of the fuel: The sudden changes in temperature and above all the condensation water that forms in the tank. The bio component present in the petrol creates a microfilm on the tank walls, forming the ideal environment for bacterial proliferation, activated by the presence of condensation drops. Considering that the injectors are increasingly sophisticated and delicate, the slightest deterioration of the fuel negatively affects their operation and that of the pumps. The MotorSistem line of professional additives offers the solution to solve or prevent the onset of these problems.
