Frequently asked questions
- How do I find my MPG?
- Fill your tank, reset the trip odometer, drive normally until nearly empty, fill again and divide miles driven by gallons added. Or check your car's dashboard display if it has a fuel economy readout.
- Can I use this for a fleet or business?
- Yes — multiply your per-vehicle figures by the fleet size, or run each vehicle separately and add the totals.
