Nissan Versa Reserve Tank

Does anyone know the size of Nissan Versace spare tank? 3

I'm trying to calculate my MPG and I want to see how many gallons are left when the gas light is on, which means it's your reserve.

Does anyone know how big the reserve tank is? Is it 2 gallons or 3 gallons?

update

It doesn't feel good because I turned on the lights and traveled 50 kilometers. The reservoir is a separate part of the tank that is turned on when the main tank is empty, which turns on the light.

All Nissan has only one EL tank, when the lights are on you can usually go another 2,530 km until it is empty.

In which tank? The salty path at the top of the tank is still a long way off. But not if you're just driving in Florida. Sorry, not enough information to guess.
