LSJr Take on Oil Filter Efficiency Improving with Loading

[ZeeOSix]

Nor do I think he would misconstrue or misunderstand something as simple as "The same principle that applies to air filters, applies to oil filters; they increase in efficiency with loading, up to a point". Is LSJR a simple minded idiot? Does he not understand the testing and the science?

I've shown many examples of the ISO 4548-12 test data that shows oil filters always decrease in efficiency as they load up. The only time the efficiency goes back up is right before they are almost totally clogged, and by that time the filter bypass valve would be opening or about to open. And that's not the point of loading you want any oil filter to get to anyway.

Ascent's ISO efficiency testing went until the dP across the media was 8 PSI above the new filter, and the efficiency of all the filters he tested continually went down over that entire 8 PSI of dP increase across the media from debris loading. The more efficient the filter was, the less its efficiency decreases with loading because they shed less already captured debris than the lower efficiency filters. There has not been one piece of ISO efficiency test data that has shown any oil filter increases in efficiency as it loads up with debris.

That's my understanding as well.

I alway think about Honda 2x OCI (14-24k) and wonder why multi billion dollar manufacturer would recommend this unless it was in their interest? I’ve been doing this for over 20 years with all my cars, bmw, Toyota and Honda.

I just finished reading the thread "LSJr on the importance of clean oil". Only took 3 days & 288 posts to come completely off the rails & get locked. Interesting. Seems like I was late to the party, which is what I prefaced my comment to Lake on the video I started this thread with. Interestingly, my comment, his reply & my subsequent reply have been deleted? Or buried somewhere?

Curiously, the answer I posted in my opening post is identical word for word to one of his answers I saw in the locked thread.

Moving ahead, we'll have to see if the promised video at Donaldson confirms or disproves his statement.

Clever way to get more viewers, eh?

Working on a "cover up" perhaps.

Either that, or he doesn't want negative comments to be seen. Not that I said anything negative about him, just contesting a statement he made.

Deleted from YouTube or BITOG?

 

[ZeeOSix]

I'd say on YT since he mentioned that LSJr responded to his (garageman402's) comment. I haven't seen LSJr here, if he even is a member.

You are correct.

Honda OEM oil filters do not have very high efficiency, so they do not get clogged easily. Also, they maybe be spinning it as “environment friendly” initiative.

He nuked it.

Run a filter for 3,000 to 6,500 miles and cut it open. On a well kept engine there won't be hardly anything on the inside.
Run it for 2 oci and run up about 10,000 miles, you'll start seeing stuff on the inside.
I changed the oil on my father inlaws car and after 4,000 miles the oil filter was as clean as a watch when I cut it open.
On my 4th hand neglected dodge Dakota beater truck the filters had a lot of junk in them after those initial 2,000 to 4,000 mile clean out oil changes. It took around 15,000 miles, several oil changes and several road trips to really clean out the engine enough to where I'll run an oil filter for 2 oci.

I say run the biggest oil filter that will fit as long as it's close to the same price and run it for 2 oci.
If there's suspected neglect or for sure neglect, change the oil filter every oci.
My dodge Dakota filled a wix 51515xp oil filter with sludge after 2 oil changes when I did it too soon.

Im thinking it would go something like this.
LSjr: we ran a 200hr test on a Dyno engine and found......
BITOGers: your stupid and don't know what your talking about. Also your face is dum.

Pretty much how it is by some, and they are loudest. I saw Whip City compare the Toyota S1 to a standard Purolator which has a larger can than the S1. The S1 has more media and the media looks good.
For a Subaru I would want the shorter filter given the orientation and start up delay and also get more media. More can, more time to fill it, for no benefits.

100% accurate. Meanwhile, folks complain about the length of his videos and will happily read/participate for most of a day on a 300+ post thread where at least 75% of it is irrelevent trash. BITOGers can be insufferable.

Lots of YT videos have around 90% irrelevant trash in their comments section, and all the lapping up of misinformation seen in the comments is pretty funny at times. Some YT videos are good and have useful information, but lots of YT "creators" are driven by how many subscribers and clicks they can get to try and rake in more cash. What's the worse are most of the true crime YT videos where there are so many "conspiracy theories" going around that some of it is totally ridiculousness. Turns people into flat Earthers on steroids, lol.

Again, I point you here...to this forum. It's really the same thing for the most part to me anyway. Sure, we have some experts here and some great info which is often burried in a sea of garbage.

I'd rather waste my time here than on YT, lol. At least on this board the truth usually comes out in the end of the various technical discussions.
