Checking the oil quality

Visible signs show effects on the oil. Fresh oil is clear to the eye, and has a typical smell and a
specific product color. Clouding or a flocculent appearance indicates water and / or
contamination. A dark or black color indicates residue, serious thermal decomposition or
contamination.
Follow the symbols in the diagrams of the Mounting positions (Page 527).
