Re: What is the best oil filter to run on a 6.0 vortec
Wix/Napa Gold are the best out there. Although I’m normally not a K&N product fan, their oil filters are a close second.
However, it sounds like you have a problem that isn’t oil filter related. You may have a worn pump, or a cracked pickup tube/worn o-ring. Both will cause oil pressure loss. The only time I have seen an oil filter actually become a restriction (aside from an incredibly poorly maintained engine causing oil caking/sludging, which no filter will repair), is a collapsed internal media on Fram filters. |

The other thing the early LS engines had to contend with was the pressure relief valve in the oil pump getting dodgy. Be it a stuffed screen, failing pickup tube O-ring, or failing pressure relief you need to address this ASAP. In comparison to the oil pump and pickup the AFM filter screen is easy to access. Get a new GM oil pressure sensor along with the AFM filter screen and replace both of them. If that doesn't fix your problem... You'll have to pull the timing cover and the oil pan to get to all of the bits and pieces of the oil pump. It's driven off the crankshaft snout. Get a Melling pump and pickup kit. Stock replacement from Melling will work great. You don't need high volume or high pressure. You may want to source a GM cam retaining plate ( these leak sometimes ) and timing chain/sprockets depending on your engine age. I would also thoroughly and carefully evaluate the harmonic balancer, serpentine belt idlers & tensioners, and the water pump while you have em off. Replacing the thermostat goes without saying. It's super cheap and you're there already. Stant or GM.
