* Driving style: Aggressive acceleration and high speeds consume fuel faster.
* Terrain: Driving uphill or in stop-and-go traffic reduces fuel efficiency.
* Fuel level sensor accuracy: The sensor itself might be slightly inaccurate.
* Specific vehicle condition: The fuel pump, engine condition, and other mechanical factors influence fuel consumption.
While some owners might get 30-50 miles, others might only get 10-20 miles. It's extremely risky to push it. Running out of gas can damage your fuel pump (especially in older cars like a 1992 Bonneville) and leave you stranded.
The safest approach is to refuel as soon as the low fuel light comes on. Don't rely on estimates; it's better to be safe than sorry.
