I noticed when changing the oil in the GTO they use a pf 44 and my Camaro uses a pf 46 - anyone know what the difference is?

The 44 was discontinued and replaced by the 46. Its basically the same filter. I have a bunch of 44's on the shelf and when they are gone, then I'll start using the 46.

The PF44 is larger than the PF46, more filtering media? If your going by the change oil light on the camaro I question using a smaller filter. There is no measuring the oil or filter quality its just a computer est. when you should change your oil, so will a smaller filter make a difference. I started buying a non-AC product to get a PF44 style still. (like AC filters) The filter is the weak link in an oil change with syn. oil, all fun and games till your in by-pass mode.

Anyone have some info on the difference.

I use the PF59 on my TA. It has a longer neck for better filtering and flow. Stock pf46 is to small IMOP

Thanks all. They are the same size, and thread. I change the oil every 3000 so the extra filtering is not an issue. I have several of the 46s and just wanted to make sure they were interchangeable.
