I will do that because I average 1000 to 1200 miles a week anyway. I changed it yesterday so I will change it next Saturday and cut open the filter, and see what it has in it. I did not know that about Ford 302 V8 engines. I always liked Ford's for trucks. When it comes to cars I love my Chevy's and some other GM's. I wonder if SBC and BBC oil filters only filter half the oil?
