Was looking online at some oil filters for Kohler engines. I found two that fit mine and the only difference besides height is microns. Not sure what micron means. Can someone set me straight on this? Will either filter work ok?
Microns is the size of the holes in the element
So the smaller the number the more debris it will pull out of the oil and the greater the pressure required to push the oil through.
The micron size for a replacement filter needs to be the same as the original one +/- 15%
Using a filter that is too fine can cause a pressure build up inside the filter high enough to activate the bypass valve so the oil bypasses the filter.
And of course the opposite happens with a bigger micron size, stuff that is bigger ends up remaining in the oil
Micron is the dirt particle size that can pass through. the smaller the number the less that can pass through.
In an engine yes no real problem.
In a hydro no micron size is king.
