Effectiveness Test

Scope: The scope of the trial was to measure the changes in fuel economy (expressed in fuel consumption) and AdBlue consumption in a fleet of three trucks over the course of one month and a distance of just over 200,000 km.

Results: The results obtained at the end of the trial were then compared to existing data to provide a quantified figure for fuel and AdBlue saving. The results are summarised below

Kenworth B 0.70 0.66 5.90%
Mack 0.68 0.64 4.90%

AdBlue Consumption

Identifier            AdBlue per km Control                                    AdBlue per km – Rox Concentrate 9300C                                 AdBlue savings
Kenworth A 0.016 0.015 2.60%
