In checking at Autozone, I noticed that there are at least three different oil filters of the Fram variety that will fit on my 440, and they are: PH16, PH43, and PH8A. PH16 is the shortest, PH43 the next taller by about a 1/4" , then PH8A is the tallest by a good inch. (I'm looking at the three right now on the floor in my office) Are these filters really interchangeable with no difference or are there differences in filtering or oil flow that I should be aware of? I would imagine the size difference carries over into other brands so this is not really about brands but about the size of the filter vs the filtering capacity. I know that the PH43 was for tight fit spots and the PH8A is the standard size but the PH16 will fit also.
I'm real curious about this if anyone has answers or opinions.
Thanks.
