Oil viscosity Use of multi-grade oils is recommended.
NOTE: Multi-viscosity grade oils are less sensitive to
temperature variations than single grade oils.
They are suitable for use throughout the sea-
sons, ensure rapid lubrication of all engine com-
ponents at cold start and get less fluid at higher
temperatures.
Table of lubricants See Fig. 1.
Since the temperature range of neighboring SAE grades overlap,
there is no need for change of oil viscosity at short duration of am-
bient temperature fluctuations.
