Whats the micron ration of this filter?

Wix #51750. The wix site does not say.

It is not unusual that a filter manufacturer fails to specify their filter's efficiency. Even when they do, the figure is suspect. They may quote some sort of number in microns, but hardly ever cite the efficiency related to that number. Amsoil is one of the exceptions.

I can't seem to get onto Donaldson's site. They don't usually list spec's on anything other than hydraulic filters ..but I figured that I'd check.
