5.4.Lubrication Oil

The lubrication oil must be changed periodically in specified intervals for obtaining the best performance and
lifetime for engine. The lubricant and this changing period is specified by the engine manufacturer, so be sure
to comply with these standards, specifications and instructions about lubrication, otherwise the engine may be
damaged.
Use a reputable brand of lubricant in accordance with API standards.
The quality and specifications of the oil to be used may vary depending on environmental conditions, so be sure to
use a proper lubricant. In some cases, if the temperature is lower than a minimum level, the engine may lose its
cold start capability so it is not advised to run the engine for a long time in such conditions.
Any further details about the lubrication system, lubricant specifications and intervals for changing the lubricant,
can be found on the "User and Maintenance Manual" supplied with engine.

5.5.Coolant

Coolants are mixtures of water, antifreeze and any other chemicals for several purposes. The main purpose of using
this mixture is cooling the engine. But with addition of antifreeze and other chemicals, this mixture prevents the
cooling water from freezing and protects the cooling system against corrosion.
Use 50% antifreeze (glycol) and 50% pure water as coolant mixture if there is any risk of freezing. By using this
mixture throughout the whole year, the engine will be protected at temperatures down to -40°C.
For ensuring an effective protection against corrosion, it is recommended to use at least 40% antifreeze inside the
coolant mixture.
Even it can be possible to decrease the freezing point of the coolant inside the engine down to -56°C, it is not
recommended to decrease it further since it may cause a decrease on the cooling performance of the engine.
In order for more precise ratios, the mixture should be mixed in a separate tank before filling
into cooling system.
Any further details about the cooling system, coolant specifications and intervals for changing
the coolant, can be found on the "User and Maintenance Manual" supplied with engine.
Drinking this coolant mixture of water, antifreeze and some other chemicals, is dangerous.
