Maintaining correct oil level is the most important and easily varying maintenance problem and or question. So many times oil level can cause service issues and the customer is unaware of the issue. Most know that low levels cause-high temperature varnishing and in extreme conditions shut downs occur it’s the high levels that are really more of a concern, oil carryover, premature separator failure, and in extreme cases, end air usage product damage.
Because of gauge movement when most air compressors are running, users tend to add more oil than necessary. Always turn to manuals when questions arise but my advice is to leave levels on the lower end, this can only save on maintenance issues. Of course this must be incorporated with clean coolers and proper filter maintenance but that is for another day.
