a) Viscosity:
Use of multi-grade oils is recommended. Viscosity of multi-grade oils is less depending on tem-
perature compared to single-grade oils. Multi-grade oils can be used year-round; after an engine
start at low temperatures the engine components are lubricated faster and at higher temperatures
the oil is heavier. Temperatures of adjacent SAE-classes overlap, so for short-term temperature
variations there is no need to change oil. The suitable oil grade can be chosen from the table.
