What to do with the number
Real-world MPG changes with speed, weather, traffic, terrain and vehicle load. For a round trip, enter total miles rather than one-way distance.
Planning estimate
Use this result as a starting point, not a guarantee. Product specifications, site conditions, manufacturer guidance, local codes, taxes, labor, tolerances, and rounding can change the real requirement or cost.
