(Translated from the original approval letter)

Dear Sir,

In this letter we certify that our department has been able to verify that in several co-generation [power] plants equipped with DEUTZ diesel engines working with heavy fuel oil, where the fuel is regularly treated the “rb bertomeu” beco F1/ASF additive (for 1-4 years depending on the plant), there has been no breakdown, or anomaly attributable to the use of this additive in any of the various parts of the engines checked.

The maintenance and service schedules have been maintained without problems. Exhaust valves, injector nozzles, turbo blades and gas nozzle rings were clean.

In line with the positive results obtained in recent years, and given that RB BERTOMEU S.L.  guarantee that their product will not cause engine damage, and will accept responsibility if this should happen, we authorise the use of “rb bertomeu” beco F1/ASF additive in our engines.

We also authorise the use of this letter for reference purposes.

Yours faithfully
