Kenworth Cummins Quad Road Trains - Fuel Efficiency Trial


Biotechnix installed the Biotechnix Fuel System on this Kenworth prime mover on October 28th 2011.

The truck is powered by a Cummins Signature 6 cylinder diesel engine rated at 525hp. It is used exclusively for coal hauling from the Acland Coal Mine to the Jondaryan Loading Facility. 


  • To compare the improvement in diesel fuel consumption after installing the Biotechnix Fuel System with the 2 months prior to installing the Biotechnix Fuel System. 


  • After the Biotechnix Fuel System ‘bedded in’ (approx. 2 weeks) the fuel saving became evident. 
  • At the end of the project the overall fuel saving across the two and a half months (49,919 kms) was 4%. This equates to 9,770 litres of fuel saved per year. 
  • Using a fuel cost of $1.45 per litre this translates into a projected saving of $14,167 per year or $28,334 over a 2 year period. 
  • Carbon emissions were reduced by 2.23 tonnes per month or approximately 26.8 tonnes per year.  
  • Drivers commented that
“We have another one and a half gears and more torque.”
