About 200 miles ago I needed to do an oil change. So today I had time and went into WalMart. Scooped up my Valvoline oil and AC Delco filter. To my suprise the PF47 was a PF47e. Uh..ok. Same long part number.
I compared them and they are the same. No welded top like they seem to all be now, flat top, same thread, diameter and height.
Just a FYI I guess unless someone knows what they did differently. I dont see any differences tho
