Blackening of lubricating oil
Thread Content
I would like to ask the experts: what causes the lubricant to turn black during use? Is this normal? If it’s not normal, what are the reasons for it?
There are several reasons why lubricating oil turns black: one is the deterioration and oxidation of the lubricating oil； Second, the lubricant used is not suitable ； Third is mechanical wear. Take samples for analysis to find the cause!
Mechanical wear is the most common issue; check the equipment – in most cases, it’s the components that are worn out
