Tips for a closer estimate
- Use your own measured MPG (from the MPG calculator) rather than the window sticker — highway and city differ a lot.
- Check fuel prices along your route; prices vary by region and by station.
- Add a buffer for detours, idling in traffic, or air-conditioning use — the tool computes the straight-line math only.
Amounts show a $ sign but mean whatever currency your fuel price uses — no conversion is applied.
