How much fuel is left when the fuel light comes on in a 1999 miata?

In a 1999 Mazda Miata, the fuel light typically comes on when there are about 1.6 gallons (approximately 6 liters) of fuel remaining in the tank. This serves as a warning to the driver that it's time to refuel soon, as running out of gas can lead to fuel system issues and engine damage. It's advisable to refuel as soon as possible once the light activates.
