Frequently Asked Questions
Should I use MPG or km/L?
Use whichever matches your car’s dashboard. MPG pairs with miles and price per gallon; km/L pairs with kilometers and price per liter. The calculator adapts automatically.
Does this include tolls or wear and tear?
No — it calculates fuel cost only. Add tolls, parking and maintenance separately for a full trip budget.
