Distillate fuel
The fuel should be a high quality mineral oil product, have good anti-oxidant properties, not sepa-
rate in storage or block the filters with wax exudation and should be free of mineral acids.
One must differentiate between two types of distillate fuels:
Pure distillates
which are known as gas oil, marine
gas oil
, Diesel etc. These are fuels with a rela-
tively low sulfur content and very good ignition characteristics.
Distillates or mixed fuels
which are known as
marine Diesel oil (MDO)
, Diesel fuel oil, marine Diesel
fuel (MDF) etc.
These types of fuel differ from the former types in general by their higher viscosity, specific gravity
and, in some cases, considerably larger tolerances.
Normal specifications for fuels:
Fuel type Gas oil Marine Diesel oil
