For a filter, get one that mixes in glass fibers in with the cellulose. Cheap filters just have cellulose paper. Glass fibers in there mean the filter is harder to clog and might get smaller particles too. Glass fiber-enhanced ones are Mobil1 M1C-254, Bosch Premium 3474, NAPA Gold 7090, Fram TG8765, or Pennzoil Platinum HPZ-55. The NAPA Gold 7090 appears to be the cheapest by far glass-enhanced filter available. I've seen the Mobil one filter go for $20 (ouch!) and I doubt if its any better than the other glass-enhanced media filters.
Go for any synthetic 5w-30 engine oil that lists the HTO-06 and GM 4178M specs. And dexos1 is good to have on top of those two performance specs, because dexos1 adds good wear performance and anti-foaming requirements.
I know its beeen said that dexos1 qualification supersedes GM 4178M, but remember 4178M had a stronger high-temperature requirement that tolerates less oxidation (thickening) and volatility (boil-off) on a standard engine test called Sequence IIIE which is part of the basic SN qualification. Personally, I've seen some reason to believe that SOPUS (Quaker State, Pennzoil synthetics) products are best for the least engine deposits too.
Then get a Dimple (strong magnet) magnetic drain plug to get iron/steel particles out in the 1 to 30 micron range.
