Which oil filter would you use?

[pbm]

I'm starting to think about my fall O/C in my GM 3.1 and I'm going to use full synthetic for a 6 to 7K OCI. I have the following filters onhand:

1) Purolator PP
2) Purolator Pureone
3) ST
4) AC (both Delphi and Champion versions)

I'm leaning towards the Puro PP because of its flow/filtering/capacity. The Pureones I like in warmer weather when cold, thick oil isn't such an issue. The other 3 are good filters but I think the PP flows a bit better. Is my thinking correct? Opinions?

I have the same engine and I don't think it's a good candidate for the longer o/c intervals. I use S-T dino and filters and change twice a year with your mileage. Even though mine has had the intake manifold replacement I wouldn't leave the same oil in for a year.

That's easy Fram Extended Guard.

I have found an AC has half again as much filter media as a PP. wouldn't use anything else if anybody but my stealer stocked my numbers.

I've used the Pure One in winter before. Try the longer filter designed for the GM 4.3 V6. It should fit with no problem.
