I am looking at oil filters and I was looking at the Donaldson brand of oil filters, are they good? Which are the best? Not air filters but oil filters.

A good brand to look at is Amsoil. They are the pioneers of synthetic oil and oil filtration. My uncle is a Master mechanic and he swears by Amsoil products. He wouldn't even think of putting any of that crappy Mobil 1 stuff in any of his engines. He has finally persuaded me to put Amsoil oil and filters in and on my car. Good luck with your search.

Puralator Pure 1 is what I use. Wix and Amsoil are the other two I would use. IMO K+N is not the way to go.

Someone page Patman. Let him drop some knowledge here for you guys...

Use the genuine GM parts.

AC Delco PF-58 or PF-59 will get you the same filter as your stock PF-44 except longer (more filter media)

Stay away from FRAM. Cheaply made.

I am wondering this as well, since I am looking into installing an oil cooler; I could go to a remote filter at the same time (read: I would no longe be restricted to oil filters that will fit onto the motor/not hang down too much; would also get the oil filter away from the headers).

I am considering a re-usable/canister filter at the moment; the two that I am looking at right now:

http://www.cmfilters.com/
http://216.149.59.51/ (System 1)

I am leaning towards the CM pieces at the moment, because of the 8 micron claim. However, I will need to call them tomorrow to see if they have flow ratings on their filters; all they say on the site is "CM elements filter out particles down to 8 microns, half the size of what the average spin-on filter does and has a flow rate even when contaminated, that is far greater than that required by any automotive application," and "When the normal operating oil pressure has decreased 4 lbs. to 5 lbs. the filter should be changed."

Conversely, the System 1 pieces offer flow ratings, a 60 micron claim, and a re-usable element.

I use the Donalson filter. They work well.

First of all, you guys should check out this thread:

It's just the beginning stages of the test, with cold oil, but the hot oil portion is coming soon.

I personally think the K&Ns are one of the best filters out there, but a bit pricey. I am switching all my vehicles over to the Carquest premium filters, which are identical to Wix, NAPA Gold and Kralinator. They flow well, and don't cost an arm and a leg. The Walmart Supertech filters are also pretty good believe it or not, and only $2 each!

Whichever one you go with, be sure to use the longer version which cross references to the AC PF59. So that means a K&N HP2006, or in the Wix made filters, get the ones with the last three digits being 522.

The Amsoil filters are good also, but they are pricey and harder to find. I don't know anything about the Donaldsons.

I would avoid the Frams for sure due to quality issues (even though it flowed very well on Bob's testing), and don't care much for the Mobil 1 or PureONE due to flow restriction issues (although we'll see more when the hot oil portion of Bob's testing takes place)

Don't worry so much about finding a filter that takes out super small particles. Honestly, if you use a good air filter (not a K&N, which lets in too much dirt) and are running a quality oil, you won't have a lot of contamination in the oil to be trapped anyways, so oil flow is a more important feature in an oil filter than getting one which traps the tiniest of particles. Also keep in mind, the LS1 has large enough clearances that a 10 micron particle, or even a 15-20 micron particle, won't really do any damage, it'll just float harmlessly in the oil.
