When a Star runs out of fuel, it will expand into what is known as a "Red Giant". Massive stars will become "Red Supergiants". This phase will last until the star exhausts its remaining fuel. At this point, the pressure of the nuclear reaction is not strong enough to equalize the force of gravity and the star will collapse.

Neutron stars do not have fuel. A neutron star is a remnant of a star that has already died.
Fusion, 2 hydrogen atoms turning into one Helium atoms continuously. (until the hydrogen runs out)
Learning about stars can be fun. A red giant star is a star with a mass like the Sun, after it runs out of fuel it can become a white dwarf or end as a supernova.
The first stage is jettisoned, to fall back to earth, as the fuel runs out.
A spaceship runs on fuel
binary stars are two stars that orbit each other while supernovas and novas stars are stars that explode when it runs out of fuel
Neutron stars could form in places where there are high-mass stars. After the star runs out of fuel in its core, the core collapses while the shell explodes into the space as supernova. The core would then become a neutron star, it might also become a black hole if it is massive enough.

Initially it is hydrogen. When that is spent, stars move to fusion of helium. There are also other fusion processes which take place: which process depends on the stars' mass.

Stars have to be 100 times more massive than our sun in order to become a black hole. When the star dies, it explodes violently (which is called a supernova) and then gravitational collapse causes it to form into a black hole.

When the star runs out of fuel. Most stars burn (fuse, actually) hydrogen. When this runs out, what happens next depends on the mass of the star... heavier stars can fuse heavier elements for a short time, but lower mass stars simply collapse into white dwarfs.
It cannot. The sun does not have enough mass to form a black hole. When it runs out of fuel an dies it will form a dense remnant called a white dwarf. Only stars 25 times the mass of the sun or more have strong enough gravity for their cores to collapse all the way to a black hole.

The best car you could get that is fuel efficient is any form of hybrid. They combine electricity and fuel to put out amazing gas mileage. When the electricity runs low the gas kicks in.
