Fuel Information
Use only fuel as recommended in this section.
NOTICE
Fill the fuel tank at the end of each day of
operation to drive out moist air and to prevent
condensation. Maintain a constant level near
the top of the tank to avoid drawing moisture
into the tank as the level decreases.
Do not fill the tank to the top. Fuel expands as
it gets warm and can overflow.
Do not fill the fuel fillters with fuel before
installing them. Contaminated fuel will cause
accelerated wear to the fuel system parts.
Drain the water and sediment from any fuel stor-
age tank before it is refilled. This will help prevent
water and/or sendiment from being pumped from
the fuel storage tank into the engine fuel tank.
Fuel Types
DAEWOO Diesel Engines have the ability to burn
a wide variety of fuels. These fuels are divided into
two general groups, preferred and permissible.
The Preferred Fuels provide maximum engine
service life and performance. They are distillate
fuels. They are commonly called diesel fuel, MDO
diesel, furnace oil, gas oil or kerosene (for cold
weather operation).
Experience has proven that distillate fuels meeting
the following basic specifications will result in opti-
mum engine performance and durability.
DAEWOO strongly encourages the use of fuels
that meet the Preferred Fuels specification.
The permissible fuels are crude oils or blended
fuels. Use of these fuels can result in higher main-
tenance costs and reduced engine service life.
Crude oil is used to describe oils/fuels that are not
refined and are in the original state as when
pumped from the ground.
