Checking the oil quality

Signs of changes in the oil can be seen with the naked eye. 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.
