Here is the PF47 out of my Monte Carlo. Run with 5w-30 PP for 2700 miles. I put a pureone pf52 sized filter back on for the 5000 mile OCI. I am going to just start running the pureones for the whole 5000. I didn't know which manufacturer made my acdelco filter is the reason I pulled it off and i didn't want to to be disentigrating by leaving it on. Here are some pictures, looks like a wix to me. It was stamped made in USA on the bottom. Ignore the hair in the first picture.

 

That looks gross

 

What looks gross? It looks perfect. No debris of any sort in the filter.

 

this is going to be a dumb question what is pf47? is that the oil filter?
