Here is the PF47 out of my Monte Carlo. Run with 5w30 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. Does it look normal?
