Engine oil viscosity
Since oil viscosity fluctuated with temperature, so the ambient temperature of engine working area
is very important to select viscosity grade (as shown in the figure). When temperature exceed lower
limit, it may decrease cold start capacity of the engine but will not make any damage to the engine.
Higher sticky engine oil may cause the engine difficult to start, so the ambient temperature of the
engine starting is the main reference for selecting viscosity of the winter engine oil. Selecting
multifunctional engine oil may avoid oil changing caused by temperature fluctuation.
HINT:
Never add any additive to above engine oil and different kinds of oil should be avoided using at
the same time (oil mixture must be the same grade oil and it is recommended to replace in time).
Gear oil:
Recommended gear oil is Ecofliud A+
Apply gear oil in accord with SAE90 API GL-5 grade. Recommended gear oil viscosity grade is related
to ambient temperature, as shown in figure.
