Most of these engines use the same filter, It's a common filter base, same as a Ford 302, I just bought some Fram FE3600, also Amsoil EaO34, and Napa 1515 I think.
Use bigger and better filters in your OPE

Bigger filter for less money/filter ratio. That works for me.
Horizontal crankshaft engines, the filter is mounted diagonally, so it isn't going to drain back. Remote mounted like mine won't drain back. Also, if you're buying filters with failing drainback valves, that seems like a problem you shouldn't be getting yourself into.
The volume of oil isn't really relevant, only the flow. All engines move quite a bit of oil and reducing restriction increases flow and decreases filter loading. So, bigger is better, no doubt about it. And when bigger automotive filters cost less? No brainer.
Yeah my riding lawnmower calls for a little nubby filter like that. I put on a fram synthetic endurance fe3600 I believe it was. The super stendo version of the short and nubby it calls for. I'll change that filter sometime around 2030.
Make sure I get all my $13 outa that filter.

I've got a Fram PH3600 on my mower. Had to trim some plastic but it fits fine and the orange matches my mower.
Matching filter color to your ride is super important for overall filtration, engine power and life as well as fuel efficiency. All the Bitog cool kids do it. I have two matched. It's the only thing I'm better at than @Zee09 .
On a serious note, since the oil pumps on OPE are much weaker, having extra media reduces filter restriction. I have an FL-400s equivalent on my John Deere. It's gorgeous green too.

I upped a buddy’s lawn mower to the only filter in stock around me, coincidentally also the biggest filter it can fit. Hood just kisses the filter when closed, perfect.

It depends on the application. The Kohler on my Ransoms Bobcat is vertically mounted (thread side down). I can tell when the drainback is not holding because the oil level will be high seeon the dipstick before a cold start. After running a bit, it will read lower.
On my Briggs single cylinder Craftsman rider, I don't think the filter size matters at all as it is not a full pressurized system and the oil filter works more like a bypass filter and only filters part of the flow.
Sir that's a Solo cup

Efficiency and build quality is probably very similar between the two

It’s a Purolator L20195. Now, I never usually use Purolator stuff (even though I actually like them aesthetically and some of the older stuff they made), but for $4 and available locally, it’ll do just fine. The L in the model number is kind of the lower mid tier filter. It’s above the white tech line and below the blue “normal” line that we see.
Small engines are super tough. No need to get fancy with expensive filters. Many don't even have filters.
That's a vote for the Amsoil filters which are black, and match everything.
For sure, no need to do things better, let's just keep doing everything the trash @$$ way we've always done it! /s
Nobody's forcing you to take care of your equipment, sir. Do what you want.
Is there a Donaldson blue cross reference? =-P
The Vanguard I'm working with has a full pressure oil system.
If you're working with a single cylinder lawn mower, you're probably right. All the more reason to have a lower restriction filter.
