NOTE
Multi-viscosity grade oils are less sensitive to temperature var-
iations than single grade oils.
They are suitable for use throughout the seasons, ensure rapid
lubrication of all engine components at cold start and get less
fluid at higher temperatures.
Since the temperature range of neighboring SAE grades over-
lap, there is no need for change of oil viscosity at short duration
of ambient temperature fluctuations.
