Has Xado been tested by a world recognised testing authority? 

Yes TÜV Thüringen, Germany one of the worlds leading inspection agencies has tested XADO.  TÜV approval and the certification procedures are without question one of the most strictest and comprehensive testing procedures in the world and involves rigorous testing and verification that the product satisfies the strictest European regulations for the industry in which the product was designed.

TÜV unequivocally confirms effectiveness of Xado and that Xado reduces fuel consumption, increases compression and reduces exhaust emissions.  Click here to see the TÜV test results

What equipment was used by TÜV to verify their results?

The TÜV specialists used industry standard equipment to measure compression, toxicity of exhausts, as well as chassis dynamometer to measure engine power, etc. You can see additional examples of tests on customer vehicles on our testimonial page.

Why has XADO not been tested using ASTM Falex equipment?

The ASTM Falex test is the Standard Test Methods for Measurement of Extreme Pressure Properties of Fluid Lubricants (i.e using the Falex Pin and Vee Block Methods). As Xado is not a lubricant it can’t be tested with this system.

What other tests gave been carried out?

Apart from TÜV, customers and clients have carried out their own test. You can see some of these on our own web site as well as forums accross the internet.
