* Driving style: Aggressive acceleration and braking consume more fuel.
* Terrain: Driving uphill or in stop-and-go traffic reduces fuel efficiency.
* Vehicle condition: A poorly maintained vehicle might get fewer miles.
* Specific Explorer model and year: Fuel tank size and fuel efficiency vary between models and years.
Generally, the gas light illuminates when about 1-2 gallons of fuel remain. This translates to roughly 30-50 miles of driving range, *at best*, under ideal conditions. It's risky to rely on this, as it could leave you stranded.
It's best practice to refuel when the gas light comes on, or soon thereafter, to avoid running out of fuel.
