The recommendations from Ford New Holland mechanic was I could use the old filter if i soaked it in diesel over nite before the first change. Then I could follow up with the second change with the new filter. Was wondering if anybody else had done that, or if I should just suck up the expense of a new filter that just gets tossed. Main reason is I have the old filter, want to get this first change done asap, and the filters have be special ordered, so a couple days out. That will probably be the time I could get to the second change anyway. Just want good results.
