Fuel Consumption Calculator
Measure real fuel consumption with the fill-to-full method, work out trip and monthly fuel cost, and compare petrol against EV running costs. Shows L/100km, cost per km, km per litre and a benchmark scale. Fully computed in your browser.
Energy cost only — excludes purchase price, servicing, insurance and depreciation, which usually dwarf the fuel gap.
Reference ranges assume a typical 1.5–2.0L petrol or hybrid family car. Weight, traffic and driving style matter enormously; SUVs and city congestion run much higher.
