8.1 Oil Pressure and Filter
Last oil change I installed a Fram Ultra Guard since the Wal-Mart by me stopped carrying AC Delco filters. Local auto parts stores don't seem to carry the AC Delco filters either. Right after that I...

Wix is good. Napa Gold = Wix
I had pressure problems with the Purolator PureOne filters. It was restrictive enough when cold it would cause the bypass valve to open, causing my pressure gauge to go to zero.
That's why I like the Amsoil filters, better filtration and the media also flows better so there isn't a restriction.

What I was thinking....there has to a balance between filtration and flow. From a practical standpoint, what's the impact on engine wear from a 22 micron particle vs. a 20 micron particle?
Is it better to capture 95% of the particles larger than 20 microns (Wix) or is it better to capture 99% of the particles bigger than 22 microns (Delco)? Any filtration engineers out there?
20 vs 22 is minimal in terms of wear difference, and both are good for full flow. I would also bet that the Wix is getting close to 99% by the time you get to 22µ anyhow.
