14 Inlet Holes vs 5 Champ 2808

[sohccammer427]

These Champ 2808 filters are in the Champ catalog as being the correct filter for my Grasshopper mower with a 3 cylindar Kubota diesel engine.

I purchased a bunch of the regular PH2808 a few years back for a good price from Rock Auto. They have worked fine. I have used most of the so I purchased some PH2808XL thinking these may perform as well.

I've not used one yet, but a couple of observations. Not as many threads on the XL model and mostly only five inlet holes as opposed to 14 on the non XL.
Also the gasket on the non XL is a beast. Never seen a gasket so robust. The XL appears to be a run of the mill gasket.

The Kubota enging runs at full throttle when operating. Should these new XL's be ok? The lack of intlet holes has me concerned.

Yeah, Champ seems to push the more basic type filters as their xl line. Media will take into account for the holes and for your application should work well. I'd use them as you intended. Thanks

Measure the area of the 5 inlet holes, then compare it to the area of the center hole. If they're equal, then no problem. You can't pump in more than comes out anyway.

Edit: the area of the center hole is larger than the area of the opening of the pipe it mounts to. I think that probably your most restrictive point anyway. I wouldn't worry about it.

The difference in "holes" is no concern. I bet the DP across each filter, in identical testing, would be negligible in a car with a positive displacement oil pump. However, not sure what you have in your mower? Looks like a gear type pump (which is PD) but would need to look it up for sure.

Fwiw, completely agree with you. And your edited point has been oft stated here when the topic of inlet hole comparisons made. Again here, my 'speculation' total area inlets easily equal to, more likely greater than the area of oil filter mounting stud inner diameter. All that said, seeing many inlets difficult for many to get past with comparisons when discussing oil filter "flow". I would not be concerned about the 5 hole Champ.

Looks like more places for the drain back valve to leak at.

Thanks for your replies. Seeing as how this filter is actually listed in their catalog for the application in question, I will use it. It has to be tested for the application. If this were a cross reference filter I'd be a little leery.

Champ no longer lists off road and ag applications, but the Luber Finer (Champ Labs) still lists PH2808 for Kubota engines.

Use either one with confidence. I’ve used many of both on family vehicles with ZERO issues. No reason/s to be “concerned” at all.

It has to be tested for the application.

Oil filters aren't actually tested on every engine they are specified for - that would be a huge and expensive under taking. The engineers design the filter to perform correctly on what ever engine they will mount to and are specified for considering the oiling system performance of those engines - ie, oil viscosity, pump flow, etc

As far as the base plate hole difference, it's nothing to worry about as others have pointed out. The dP difference across the base plate between those two filters will be minor and won't really matter to the engine's oiling system.

I'm running a champ xl on my 21 Altima right now with schaeffers 0-20. 10 degree morning starts the last week have been uneventful, which is never bad. They seem like a well made filter to me, even if they are Ecore.
