Here’s an example. I drove from Mzuzu to Lilongwe. I bought fuel for K120,000 (prices were lower then), which would normally take me 340 kms. However, with the ECO Systems device fitted, I travelled 450 kms for the same amount of fuel and still had enough left for another 30 kms – that’s a 34% reduction in fuel required for the journey. So the point has been proved!
