His oil filter charts assumes all bypass filters are parallel to the full flow filter. That would depend how it was installed. My amsoil bypass is installed in a serial manner meaning oil only enters the bypass after it has pass thru the full flow. That prevents the bypass from clogging with particles sized between the size of the full flow and the bypass.
if you run the bypass in parallel…oil can enter the bypass filter with out passing thru the full flow.
on a ford 6.7…forgetting about the remote relocation disc …and talking about not port feeding….
if you tee tap at the oil temp sensor…your bypass will filter in parallel to the full flow.
if you tee tap at the oil pressure switch…your bypass pass will filter in a serial fashion and only get oil to the by pass once the oil has been filtered by the full flow.
there is no point in having particles greater than the full flow rating in your bypass filter.
so the point is the video is useless with out the architecture of install explained.
When I used oil guard system
it was separate from main lube filter
It tapped a feed off a small oil gallery iirc 1/8
and fed that down to the bypass filter head. Then a Return line back up to oil filler cap, through a special cap with an fitting
so it basically conditioned all the engine oil...with no pressure loss or having to deal with main fikter or filter head
sure wish they made one for the 6.7
Mine was on 6.0 and 7.3
i guess they are no longer around
It was a grrat system
My 8.3 isc main lube filet has a bypass higher micron secondary element..
not sure how much it scavenges off main filter flow.
It's a monster holds nearly 2qts
These guys are close to how oil guard worked

I run the FS2500 bypass system with the spin on filter conversion which pulls oil from the oil filter housing teed off of the oil pressure switch IIRC... low pressure flow and returns it to their replacement oil fill cap with a swivel fitting return line.
Speaking of bypass filters, been looking into centrifuge bypass filters. Just found out PPE makes one for the 01 to 10 Duramax I believe, with a replacement oil fill tube which the filter gets mounted on top. Interesting stuff to be sure. Not done looking into this...

so FS. Is still in business?
centrifugal filters for industrial equipment are huge
interesting a small one for road vehicles.
Just looked at thier site..no 6.7 yet
curious how much oil pressure is tapped to spin it at 6000 rpm
overdrive gear case🤣

I don't want to hijack this thread further, but a quick point, I have located a company that make kits for diesel pick ups and from what I have seen. it's most likely doable on my truck... but more later and separate thread.
PS The feed line would tap into exactly where my FS2500 taps in, via a tee in the oil pressure switch (sender) location on the oil filter housing.
OOh can I double my change interval with one of these? 24K oil change intervals sounds marvelous. I seriously doubt the viscosity of the oil will last 24K miles.

There are ways to find out, there are plenty of people that go further than that. I wouldn't recommend making the decision blindly.

Not without a 9th injector, UOAs and filter changes with additional oil added...
Thanks for the video. His videos are entertaining. I've seen the one where shows it doesn't matter if you pre-fill the oil filter.
I had a Frantz filter on my truck but have removed it because I couldn't run long oil change intervals anyway. Fuel dilution was an issue for me (thanks EPA) and the added cost of testing the oil and increased oil capacity just makes it not really worth it. At least with a Frantz setup, the filters are really cheap and you can buy them at Walmart. The Amsoil bypass filters are expensive. I had used a sandwich adapter but if I had to do it over I would tee off the oil temp/pressure switch and maybe run the return back to the pan instead of to the fill cap.
With the amsoil bmk 28, you loose 17psi oil pressure idling, and running down the road. The dinky 1/2" ID hoses are NOT enough to feed the full flow filter. Amsoil didn't do the research needed or they would have caught this.
PM me if you want the kit. 7 filters hoses, powder coated frame mounted brackets. ill let it go cheap
