Frequently Asked Questions
How do I measure mileage accurately?
Fill the tank fully and note the odometer. Drive normally, fill the tank again and note the odometer and the fuel added. Mileage = distance / fuel added.
Is real consumption the same as the estimate?
No. Traffic, speed, load, weather and driving style change real fuel or battery use.
Do the tools handle both miles and kilometres?
Yes. Choose the units you use and the results convert automatically.
Can I change the inputs and recalculate?
Yes. Change any value and press Calculate. The result, the table and the explanation update straight away.
Note
Real consumption changes with driving style, load, traffic and weather. Treat the result as an estimate.
