That being said, step outside your comfort zone and go with a Puro Synthetic!

I am a fan of quality. I am running an Ultra now and love the filter, rarely any start up tick unlike some other filters I have tried. I just figured that during the winter flow might be of MORE importance than outright best filtration.


Start-up tick isn't a "flow issue" ... it's a leaky ADBV issue. As said before, "flow" is not an issue unless the filter is very clogged up, and since you change oil & filter often it's not a concern.

He changes his oil every time he parks his car at night. He doesn't even need a filter.

20 microns is 1/2 the width of a single hair standing on my arm. I can't see a particle that size doing any damage. And besides that, I gotta 50 percent chance of catching it.

Read this ... see the measured wear difference between a 40 micron filter at 98% efficiency and a 15 micron filter at 98% efficiency. A filter at 60% at 20 microns looks to be about the same as the filter shown as 98% at 40 microns (the Filter A in the Efficiency vs Particle Size chart).

"Small particles are particles measuring between 5 and 25µ. Small particles are of greatest concern because they can penetrate the clearances between wear-sensitive components and promote accelerated wear. And, because they are so small, they are difficult to remove from the oil stream."

"While today's filters offer even greater performance, the message then was the same as it is now; removal of particles measuring 2 to 25µ is the key to controlling engine wear, and there is a direct correlation between oil filter efficiency and engine wear."

^^^ Everything has a trade off. I can't see how you're gonna get good oil flow while catching 20 micron sized particles 100 percent of the time. I'd rather have the oil flow.

You can have excellent oil flow and be highly efficient at the same time, just like this. The full synthetic Ultra probably flows even better than this PureOne - which is rated at 99.9% @ 20 microns.

This is what a PSID vs Flow curve looks like for a very good flowing oil filter - in this case, a medium sized PureOne (PL14006) with only about 100 sq-in of media area. I doubt your car can put over 12 GPM of oil flow to the filter - probably more like 6~8 GPM.
