if you are happy with the boss go with the puro gold 20k at Walmart same filter... but ID suggest anything PGI made as said above comes in many diff names rebranded
Looking for the most experienced oil filter expert (or moderator) to answer one question.

OK - Understood - I'm Not Knocking anyone Filters just trying to get to Bottom of all Info Out there ..
My Fram was cellulose and Lower Grade ..
Yes , Modern Cars with Turbo's & Very Tight Tolerances Run High Oil Pressures - also providing Oil Squirter's
That also Supply Oil to Chambers inside Pistons ( Oil Galleries )
In Fact I should be able to find an Old Post approx 2.5 yrs back ( Mentioning ) I removed Boss with in 1500 miles
as My Engine felt sluggish & chocked - these are My words to what You would describe as Super Mild ..
I'm Totally in Tune with How Engine is Behaving ,( EFFECT ) Boss Filter Having on 2.0T Honda ..
So any how - I noted Boss has since - Redesigned Filter do to Tighter Inspection
On Their Supply Vendors ( Allowable Spec' ) . . I Believe Purolator statement went something like that ..
Precision Glass‑Impregnated (media) - OK - that Phase is " Scary " - just reading it - glass particle inside my Engine
O M G How is that even Checked like after Bonding Agents they Do 3 Wash Cycles ?

Here's My 1954 Chevy 1 Ton - will ~ All Options ~ I ~ Doubt these made 44 PSI . . this on Has Ungraded Pump @ 55 Psi ..
LATER - DURING COVID ~
I Tried to Understand Chart - but Really don't get Meaning of Chart - what is it Saying ?No oil filter is going to make a 1.5 MPG difference. Do a hydraulic HP analysis due to the flow resistance of the dP difference between oil filters and you'll see its minuscule.
What's that filter's efficiency of that filter at 0.022 microns. You probably meant 22 microns, as 0.022 microns is super small, like 40 times smaller than bacteria. And what's the dP vs flow of that filter, like shown for the filters in the link below? If it's a K&N, then the dP vs flow is about in the average range as shown in the link below.
Pretty much all oil filters flow well with hot oil, even at 9-10 GPM which is probably way more than your mower is pumping through the filter. I'd be surprised if it's even 5 GPM, which would mean the difference in dP from different filters would be around only +/- 1 PSI.
The dP vs flow data is on one graph to easier show how they compare at 5 GPM and 9 GPM.
X-axis is the filter number from the Filter Key table.
Y-axis is the dP in PSI.
Test conditions are on the graph.
Note for the PGI filter fans, the STP Ext Life (Filter No. 18) shows to have a pretty decent dP level (middle of the range), and they are rated pretty high in efficiency too (99% @ 20u).
My Flow Rated List : I Run K&N HP ~ Filters on My Honda - Really Does Make Difference
Compared to Run of Mill Oil Filters . . could also been Clean Fresh Oil seeing Extra Hot Turbos - Kill Oil Quickly in Hot South ..

Match the filter number in the table with the flow vs filter pressure drop on the graph. Like said, oil filters are not really "flow restrictive". Most of them in the graph only have 2 to 3 PSI of dP with a flow of 5 GPM with hot 20W-50 oil.
That table tells doesn't tell you much because you don't know: 1) The viscosity of the oil, and 2) What the pressure difference is across the filter. That's the info the data I posted above shows.
The K&N HP is No. 10 in the data I showed. It's nothing special and many others flow around the same 3 PSI of dP at 5 GPM and 7 PSI of dP at 9 GPM.
You need data like this to fully understand how an oil filter "flows". This example is the old yellow Purolator PureONE which everyone that was "very flow restrictive" because it was also very efficient. A perfect example that "flow over efficiency" is a myth.

OK so More Hp used to Pump Oil with Semi Debris Filled Filter - Earlier in Life Cycle of Filter . .
HP Gain with Extra Flow is Not a Myth or More Eff% Flow - may Equal Better Mpg . .
. .
I'm just Relating : Actions of Ported Oil Pump vs Non-Ported Oil Pump - more Flow - Less Restrictive , . .
Porting ..Oil Pumps Gain 1 Hp on Dyno's
Ported Turbo's are 4% more Eff Flow = 3 Hp on small Turbo to 5-6Hp on Larger Turbo
Mostly Bring Turbo Down 5000-6000 Rpm = Cooler does same work Lower RPM ..
OK Old Guy - I'll Turn Picture to Look at it from ~ All Sides . .

Oil pump HP required to pump oil through an engine isn't related to a "semi filled filter", whatever that may mean. It's based on how much pressure it takes to force a given flow rate through the engine. Look up the Hydraulic HP Equation.If there was more oil flow, then it would take more pump HP to make that flow, so "HP Gain with Extra Flow is Not a Myth" is a total misconception.
You are patient.Misconception Award Winner.

Sorry for Being an ~ Old Guy ~ I Wander Off sometimes . . Please Understand My Mistakes as
I Thread into Unknown ,
Thank You
ps: Semi-Debris Filled Filter - in - My Book will take More HP or Cause more Stress on system . .
Reading Between Line : Extra Flow or Higher Flow Rated Filter = same .. & Removes Stress from system . .

I'm just trying to show what's really going on and tamp down some misconceptions ... hope the info helps with better understanding.Sorry for Being an ~ Old Guy ~ I Wander Off sometimes . . Please Understand My Mistakes as
