Further to testing carried out on 18 LIAZ, MAN, Renault and AVIA fleet vehicles between October 2006 and February 2007, we hereby certify that a demonstrable saving of 7.28% on consumption was achieved against comparable periods in the previous two years. This figure was obtained after discounting the effect of increased wintertime consumption. The additive used was the nanotechnology product Envirox™ supplied by yourselves, in a dosing ratio of 1:4,000.

No measurement of reduced exhaust emissions was performed as part of this testing.

We wish you further commercial success with the additive Envirox™.
