DIESEL FUEL, ENGINE OIL AND ENGINE COOLANT
DIESEL FUEL
Use fuel that meets the requirements or specification of Class
2-D (ASTM), and has a cetane rating of #45 or better.
Care Of The Fuel Supply
Use only clean diesel fuel! The clearance of the components
in your fuel injection pump is very critical; invisible dirt
par~
tides which might pass through the filter can damage these
finely finished parts. It is important to buy clean fuel, and
keep
it clean. The best fuel can be rendered unsatisfactory by
careless handling or improper storage facilities. To assure that
the fuel going into the tank for your engine's daily use is
clean and pure, the following practice is advisable:
Purchase a well-known brand of fuel.
Install and regularly service a good,
visual~type
filter/water
separator between the fuel tank and the engine. Raycor 500
FG or 900 FG is a good example of such a filter.
ENGINE OIL
Use a heavy duty engine oil with an API classification of CF
or CG4 or better, Change the engine oil after an initial 50
hours of break-in operation, and every 200 hours of operation
thereafter. For recommended oil viscosity, see the following
chart:
Operating Temperature Oil Viscosity
Above 68"F (2D"C)
SAE 30 or 1 OW-3D
41 "-68"F (5-2D"C) SAE 20 or 1DW-3D
Below 41"F (5"C) SAE 1DW-3D

CAUTION:
00 not allow two or more brands of
engine oil to mix, Each brand contains its own additives;
additives of different brands could react in the mixture
to produce properties harmful to your engine.

ENGINE COOLANT
UNNERSAL recommends a mixture of 50% antifreeze and
50% distilled water. Distilled water is free from the chemi-
cals that can corrode internal engine surfaces.
The antifreeze performs double duty. It allows the engine to
run at proper temperatures by transferring heat away from the
engine
to
the coolant, and lubricates and protects the cooling
circuit from rust and corrosion. Look for a good quality
antifreeze that contains Supplemental Cooling Additives
(SCAs) that keep the antifreeze chemically balanced, crucial
to long term protection.
The distilled water and antifreeze should be premixed before
being poured into the cooling circuit.
NOTE:
Look for the flew environmenwl(v-jriendiy IOllR la.l'finf!,

Antifreeze mixtures will protect against an unexpected freeze
and they are beneficial to the engine's cooling system. They
retard rust and add to the life of the circulating pump seal.

A coolant recovery tank kit is supplied with each
UNIVERSAL diesel engine. The purpose of this recovery
tank is to allow for engine coolant expansion and contraction
during engine operation, without the loss of coolant and
without introducing air into the cooling system. This kit is
provided and must be installed before running the engine.
