FAQ
Does higher MPG always save more?
At the same fuel price, yes; but vehicle cost, insurance and maintenance also matter.
How do I estimate an EV?
Use kWh per 100 miles and electricity price instead of MPG and gas price.
What if fuel is priced per liter?
One gallon is 3.785 liters; multiply the per-liter price by 3.785.
