Amsoil bypass filter- does it lower oil pressure?

Maybe this will shed some light for those that can't comprehend a bypass system.

The title "never change oil again" is identical, in every important respect, to "why the earth is flat" or "here's an actual perpetual motion machine".

Decent vid, but I call bullshit @19:19. There's no way that oil at 470 miles (or at any miles) will have fewer contaminents than virgin oil, and in fact the video itself shows my lying eyes that it doesn't.

Filtration has no effect on the chemical degradation of the oil, so you'll always have to change it regularly no matter how good your filtration system is. I don't expect that it will significantly increase oil life (although I'd be happy to be proven wrong).

Hopefully he will have another video of the oil analysis from 5000 miles. Caterpillar and several other manufacturers do not recommend pre-filling filters do to the amount of contaminate in new oil.
I am trying to change anyone's mind on the subject. I know that is nearly impossible to do. I was just putting out some insight on the process.

The oil in the bottle is not contaminated. I suspect that the issue is the risk of something falling into the filter (the foil seal of the bottle, perhaps) and then blocking an oil passage.

I know more than a few engine lubrication system design engineers. Some of them have been doing that job for decades. None of them pre-fill the filter or use clear-flood mode when they change their oil. If they don't worry about it, I figure I don't need to either.

I do look forward to his updates.

That is significant IMO. I’m interested in adding either the Insane Diesel kit or the Amsoil however my biggest fear is the non crimped hoses and the many potential leak/failure points. Break a hose or have one blow off and you are in trouble quick Without even noticing till it’s too late.

It is a rip off. After 10k the oil is just as black as if you used a OEM filter. Here is why, and you wont hear this from anyone. The Amsoil full flow only filters down to 20 micron. (for comparison, Motorcraft filters to 10 micron) The bypass filter is a 2 micron filtration. Here lay's the problem, Soot is "less" than 1 micron. So the Amisol can only trap soot that has clumped together, which is what they hope happens. This is why there filter is not very efficient at removing soot. An the full flow allows to many partials under 20 micron which in todays engines 20 micron is large. If I where to install a Bypass in the 6.7 I would install the one from Insane. For two reasons, I know of two motors that have run over 800K with these on them. Are they the reason they lasted. No idea. But the engines were cleaner than some with 100 to 200K. Second reason is that it uses the OEM filter. An as stated the Motorcraft filter, filters to 10 micron, and the Insane bypass filter it down to 1 micron. Again soot is less than 1 micron. But you will catch more with 1 micron filter than a 2. My opinion form a month of research when I was going to install one.

I have a 2011 6.7 with the Amsoil By-Pass. The truck has been deleted and tuned with other modifications. I have NEVER had issues with the By-Pass set-up, and I do not regret installing it. At this point, I will not consider buying a new or new used truck, all because it takes time and money to get the truck where it needs to be. Additionally, I sample my oil once a year, and based on the results of the test samples, the engine is in excellent condition. Each is their own; what someone likes, someone else might not.

Sorry, I miss spoke. It is WIX that has a filter for 10 micron

Just to be clear, assuming we are talking about 6.7 Power Stroke filters, the WIX XP 57151XP "Oil Filter Laboratory Test Performance per ISO 4548-12: 32 grams dirt and 99 percent efficient at 35 microns," according to OReillys.com. The WIX non-XP version, 57151, has "laboratory test performance per ISO 4548-12: a dirt-holding capacity of 18 grams and 99% efficiency at 23 microns," according to RockAuto.com. The Motorcraft FL2124S, with a "cellulose and polyester blend filter media, is tested to achieve 80 percent efficiency on particles of 20 microns or larger," according to RockAuto.com and parts.ford.com
