Vehicle Test Reports
Many of our clients ask for test reports as evidence of the effects of XADO. We are happy to provide the following XADO test reports. They show the real improvement that XADO can make to performance and particularly to the reduction of polluting particulates and NOX.
TÜV - Europe's Leading Testing Agency Approves Xado
TÜV Thüringen, Germany, one of the world's leading inspection agencies, confirms the effectiveness of Xado.
XADO revitalizing claims were extensively tested at the TUV testing centre, the Technical University of Zwickau, Germany. Over a period of several months, TÜV Technicians tested, recorded and compared engine performance before and after using XADO.
TÜV approval and certification are without question one of the strictest and most comprehensive testing procedures in the world and involve rigorous testing and verification that the product satisfies the strictest European regulations for the industry in which the product was designed.

TÜV also confirmed that the XADO CERMET layer created by the treatment optimised the surface of the engine cylinder walls, which led to reduced fuel consumption, increased compression and reduced exhaust emissions.
These results overwhelmingly confirm the effectiveness of XADO.

The revitalisation potential has revolutionised the contemporary ideas of vehicle and mechanism operation and repair. Scientifically, while beautiful in its simplicity, the concept of the wear process reversal is embodied in XADO products.
