Diesel Fuel Requirements
Perkins is not in a position to continuously evaluate
and monitor all worldwide distillate diesel fuel
specifications that are published by governments and
technological societies.
The "Perkins Specification for Distillate Diesel Fuel"
provides a known reliable baseline to judge the
expected performance of distillate diesel fuels that
are derived from conventional sources.
Satisfactory engine performance depends on the use
of a good quality fuel. The use of a good quality fuel
will give the following results: long engine life and
acceptable exhaust emissions levels. The fuel must
meet the minimum requirements that are stated in
the table 9 .
