Looking at two different filters from wix for hydro-static tractor, I find one that is cross referenced from Donaldson, and another from crossing the oem part number. They are both the same in fitment, however, the beta ratio and micron ratings are different. Which filter would be the best? .....,,,,,,,,,...,,,,,.wix 51455 http://www.wixfilters.com/Lookup/PartDetails.aspx?Part=61853 Part Number: 51455
