So what\'s so good about big oil filters

I changed my oil last night. Per information gathered on this BBS, I bought a ACDelco instead of a Fram. The ACDelco was smaller, is that a problem?

Not a problem, but a bigger filter means more filtration.

Re: So what\'s so good about big oil filters

Just how much smaller is the Delco than the Fram? My Cherokee's Chevy 2.8L has a small 1/2 quart filter (PF 47 in AC Delco). Never had a problem changing the oil every 3 months/ 3k miles. Every brand of filter I buy for it is the same size, though. In my case a larger filter won't fit in the space.

A larger size filter has more overall particule capturing and holding capacity and will last longer than a small one. Both the small and large will capture the same size particules. When a filter becomes overloaded, like when it is left in the system too long, it "unloads" itself by letting the captured particules migrate off the filter media and back into the stream, thus eliminating the filter's usefulness. Good Luck [img]/wwwthreads_images/icons/smile.gif[/img]

Re: So what\'s so good about big oil filters

I believe that the determining factor is the area of the filtering medium

<font color=red> in this case-the folded paper filter inside the case</font color=red>

my point being that the size of the container does not nessesarily determine the capacity of the filter.

I changed from the Fram to the Delco on my 304 too. It looked to be about the same size to me. Cool blue color too!
