To be quite honest, it isn't difficult and that is why the oil
companies are so worried. because with a few simple ingredients, that
you already use when cleaning windows or camping, you can convert
rapeseed oil to diesel for your car.
You can make it in your own garage and drive for a fraction of the cost
of fossil diesel.
And that is not all...
Biodiesel is actually cleaner than normal petro diesel, it does not add
any carbon dioxide to the environment, because the plants used to make
the raw oil consume carbon dioxide while they grow. Reduce greenhouse
gasses in one go!

My car runs on gasoline.

Plants don't consume CO2 when they grow. They give off CO2 when they
respire just like all living things. The process of photosynthesis
has a net positive amount of oxygen during the day, but at night they
are only giving off CO2.

Carbon dioxide is added to the air in any combustion process (unless
there isn't enough oxygen in which case it is carbon monoxide)
regardless of how the fuel was made.

Biodiesel only works for cars (or boats) that have diesel engines.
And you don't have to use rapeseed oil, you can get used fryer oil
from the fast food places and use that.

For gasoline engines, you distill ethanol to get gasahol.
