Yeah 20 is pretty good. Who wants to spend $30 to $50 on an oil filter that needs to likely be changed every oil change. There's a white paper on here that breaks down engine gunk by particle size. Catching most of the say 3 to 15micron bits would increase the dirt load on the filter something like 20% if I remember correctly over a 20micron.
I prefer to change them at 5K rather than cut into the can at 15 or 20K and wonder did it turn into a tearolator at 500 miles or at 14.999?
Guess we'll see. I've cut open dozens of OCDs that were ran for hundred hours and a few OCD, wix, napa that were ran for thousands of hours. None showed any signs it was about to give up.
Good roll up ! … I wonder how these filters would rank in ease of flow / flow rate ? Before their current production questions arose - the Fram Endurance had the highest flow rate combined with one of the highest filter efficiency .
My bet it the flow vs dP curves between all those filters is only going to be +/- a few PSI with hot oil. Not enough to matter to a PD oil pump on an engine, and all will flow way more than the engine needs.
Good point, the data is lacking. Too much of a bandwagon for me to buy PG. Always suspicious of too much promoting by owners of products. Gets pretty overboard here.
Hopefully M+H and First Brands can get their act together. Kind of an embarrassment currently…
I wonder if NAPA left the old M+H built NAPA Gold filter efficiency up on their website? If the PG filters for the NAPA Gold are really 99% @ 30u them maybe NAPA specified that target and the media is different in them.
There’s a little locally owned Napa franchise near me that I enjoy going in. Usually has his filter prices set reasonably. The NG for my Ram is $8 normal price.
I'd do more digging on the NAPA efficiency claim. Maybe contact NAPA directly if possible and verify if the efficiency info they show on their website is accurate for the PG made NAPA Gold filters, or is it left over M+H efficiency info?
I'm thinking 10k is probably enough.
What I was thinking reading post #3 - you run them twice as long … or what I’m doing in two runs of an OTC synthetic and Fram Ti …
Often the difference is having no bypass at all in the hydraulic filters.
Or it has a kidney loop system - and on and on. Many hydraulic systems are custom designed per application …
These are low pressure filters. They'll burst at more like 250psi.
Band wagon is like a picture of something. People jumping on things influenced by others opinions. So there is this band on a wagon all tooting the same song.
