I found this a pretty interesting article, so I just thought I'd pass it along.
I especially like the writer's suggestion for new testing, "Despite the fact that there is not currently a standardized test protocol to provide a quantifiable measure of IHC, it still can be referred to in relative terms. To my knowledge, there’s also no standardized test method to quantify the soluble fraction of water in oil.
However, the concept of an oil’s dew point, saturation point or relatively humidity is abundantly clear to those performing oil analysis and formulating lubricants. The same applies to an oil’s relative IHC (instead of relative humidity), IHC (instead of saturation point) and impurity floc point (instead of dew point)."

What is Your Oil's Impurity-holding Capacity (IHC)?
There has been much said in recent years about the increased propensity of some modern oil formulations to produce sludge and varnish. Ironically, many of the oils accused of contributing to...
