Oil

Important

• The engine may be damaged if operated with insufficient lube oil. It is also dangerous to supply too much lube oil to the engine

because a sudden increase in engine rpm could be caused by its combustion. Use proper lube oil to preserve your engine.

Nothing affects the performance and durability of your engine more than the lube oil you use. If inferior oil is used, or if your

engine oil is not changed regularly, the risk of piston seizure, piston ring sticking, and accelerated wear of the cylinder liner,

bearing and other moving components increases significantly. Always use oil with the right viscosity for the ambient temperature

in which your engine is being operated . Use the chart when chosing your engine oil.

• The used engine oil can cause skin-cancer if kept frequently in contact for prolonged periods. If contact with oil cannot be

avoided, wash carefully your hands with water and soap as soon as possible. Do not disperse the oil in the environment, as it

has a high pollution power.

SAE classification

In the SAE classification, oils differ on the basis of their viscosity, and no other qualitative characteristic is taken into account.

The first number refers to the viscosity when the engine is cold (symbol W = winter), while the second considers viscosity with

the engine at régime.

The criteria for choosing must consider, during winter, the lowest outside temperature to which the engine will be subject and the

highest functioning temperature during summer.

Single-degree oils are normally used when the running temperature varies scarcely.

Multi-degree oil is less sensitive to temperature changes.

SAE 10 W *

SAE 0 W - 30 ***

Lubricant international specifications

They define testing performances and procedures that the lubricants need to successfully respond to in several engine testing

and laboratory analysis so as to be considered qualified and in conformity to the regulations set for each lubrication kind.
