How much can you save on fuel costs with FuelMarble?
How do you calculate fuel cost for a commercial fleet?
To calculate fleet fuel costs, multiply the average daily distance per vehicle by the total number of active days and the number of vehicles. Divide this by the average fuel efficiency (MPG or km/L) and multiply by the current fuel price. This establishes your baseline expenditure before optimization.
What is the payback period for fuel saving technology?
The payback period, or ROI, is calculated by dividing the total cost of the hardware (FuelMarble units) by the monthly fuel savings. For high-mileage fleets, this break-even point typically occurs within 3 to 10 months per unit, as confirmed by our ROI calculator benchmarks.


Why does vehicle weight determine FuelMarble unit size?
Combustion optimization requires different surface area treatments based on fuel flow rates. Vehicles weighing less than 2 tons use FuelMarble S, while those weighing 2-4 tons require FuelMarble L. For heavy-duty applications, trucks weighing 4-13 tons require 2 L units, while those over 13 tons require 3 L units to effectively handle the substantial fuel volume.


Fleet ROI Case Study: 5-Vehicle Delivery Team
A fleet of 5 light commercial vehicles (below 2-ton) traveling 30,000 miles each per year at 35 mpg (£1.45/L) incurs a total annual fuel cost of £28,215. By applying FuelMarble technology to achieve a 10% efficiency gain, the fleet reduces expenditure to £25,650, generating a total annual saving of £2,565 and achieving full payback on the hardware investment within months.
