Jones Bros | 3.72% Fuel Saving Trial
Jones Bros Cuts Fuel Use by 3.72% and Eliminates Fuel-Related Breakdowns Following FuelActive Trial
Proven results
The Challenge
Leading civil engineering and infrastructure contractor Jones Bros Civil Engineering approached FuelActive to explore how the technology could help reduce fuel saving in earthmoving across its projects while supporting the company’s wider sustainability objectives.
The Solution
To verify performance, a controlled trial ran from March to October 2025 and was designed to deliver a true like-for-like comparison under real working conditions. Twelve articulated dump trucks were deployed on the same site, undertaking identical duty cycles, utilisation rates and payloads. Six Volvo A40G ADTs were fitted with FuelActive, while six operated without the system as a control group.
“With FuelActive now integrated into our fleet, we’ve improved operational reliability, reducing fuel-related downtime and ensuring our equipment delivers consistent performance on site."
Huw Jones, Chairman of Jones Bros
The Benefit
Using OEM telematics data, the company analysed 27,000 individual data points over the eight-month period. The findings showed that machines equipped with FuelActive consumed 3.72% less fuel than their counterparts. That equates to an annual saving per machine of 1,295 litres of fuel and £1,450 in cost reduction, alongside a projected CO₂ reduction of 3,400kg per machine, per year.
While the fuel and emissions savings are significant, operational reliability proved equally compelling. Throughout the entire trial period, the FuelActive-equipped machines recorded zero fuel-related breakdowns.
FuelActive replaces the conventional bottom-of-tank fuel pick-up with a floating pick-up that draws the cleanest available fuel from the tank, helping prevent water and sediment contamination from reaching modern high-pressure injection and after-treatment systems. For Jones Bros, this translated into greater operational consistency and reduced risk of unexpected downtime on site.
