Choosing a diesel or gasoline engine

A diesel engine will go much farther on a gallon
of fuel that the standard gasoline engine
because of their designs, and due to the higher
energy density of a gallon of diesel fuel.  But,
it also takes a bit more oil to manufacture a
gallon of diesel than a gallon of gas, with
the production and refining processes for
diesel producing [...]

Diesel Versus Spark Engine Ignition

As you may already be aware of, diesel engines are
more efficient than gasoline engines of the same
power, resulting in much lower fuel usage.  For an
efficient turbo diesel, the average is 40% more miles
per gallon.  The higher compression ratio with
diesel engines help to raise efficiency, but diesel
fuel also contains around 15% more energy per unit
volume than [...]

Diesel Fuel Quality

The designs of diesel engines striving to increase
performance have made a lot of advancements in engine
fuel delivery to the combustion chamber.  The diesel
engines of today are much quieter, smoother, and
also more powerful.  The quality of diesel fuel on
the other hand has not advanced at the same rate as
the improvements of engines.
As soon as it is [...]
