There are 2 different Oil Filter listings for my '93 4.9 DeVille.

After a little research, it seems like one has a Drain Back Valve and one doesn't.

Which one is the correct and/or better one to use.

The ones I have been reseaching are the:

AC PF 61 and the Hastings LF 164

compared to the:

AC PF 59C and the Hastings LF 487


Thanks

Bill

I have been always using PF61.

I`ve always used AC PF 61 on my 1995 Deville 4.9 litre.
