Use bigger and better filters in your OPE

I have a kohler command on my z-turn and I can't figure out which filter to use on it. I found something *close* from supertech and it seems to work but I'm not sure it's ideal.
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.
 
The primary reason I use a larger than spec filter on my JD mower w/B&S 21hp engine is because I can get the automotive (3614&equivalent) application for significantly less than the OPE. And many times that means it has silicone adbv vs nitrile in the OPE. I see some suggest even bigger 3600, and 'for me' that's overkill. 3614 plenty enough, especially after seeing what a Napa Gold 1348 looked like after 7 plus years as posted here. So if room permits, using an automotive application in place of the OPE, a pretty much a no brainer imo.
Bigger filter for less money/filter ratio. That works for me.
 
For OPE oil filters, it seems to me that bigger is not necessarily better. OPE oil flow rates are lower than automotive applications and if the anti-drainback valve in an extra large oil filter fails, it will take even longer for the filter to fill before oil can circulate to the engine. Just how big of a filter does one need to efficiently filter a whopping 48 ounces of oil?

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 .
 
3614 can be upsized to a 16, which can be upsized to an 8, which is the equivalent of an FL1a. imagine that beast on a lawn mower
 
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.
 
what brand is it? never seen a red filter before, only white/black/orange/grey/blue
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.

That's a vote for the Amsoil filters which are black, and match everything.
 
Small engines are super tough. No need to get fancy with expensive filters. Many don't even have filters.
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.

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.
