I am wicked horrible at doing searches, I cannot believe that there isn't a thread dedicated to the various Oil Bypass Systems available. But I couldn't find one.

Now that I've installed the coolant filter, a supplemental fuel filter / water separator I'm on the hunt to better filter my oil.

Doing internet searches the one that pops up most often is the AMSOIL bypass system, looks like Donaldson, Frantz, FS-2500 and KleenOil also make them.

What are you using? Do you like the one you're using? Would you choose another brand if you had to do it again? Are there others that just didn't come up in my internet search or one that just doesn't advertise?

 

You put coolant filtration on a 6.7? Why is that?

 

Paranoia mostly, another reason is when checking my fluids I always notice crud around the overflow tank cap. Also read a couple horror stories of folks finding all kinds of crap in their coolant. Figured for $175.00 the insurance / piece of mind was worth it. I'll crack open the filter after my 1st 3 month stent and see what I find

Back on topic - I think I may go with the Insane Diesel Extreme bypass oil system. What's holding me back at this point is that it appears as though you need to take a hose off when you go to add oil. I haven't asked them yet, just looked at the install instructions so may not need to do that.

 

 

I couldn't add text to the reply box because I linked the photo first...so I'll do it here. There's no hose to remove to add oil, Chuck. The hose is attached to the swiveling nipple on top of the new ported fill cap. I believe the Amsoil bypass filter also uses a ported oil fill cap also as it's probably the easiest place to return the oil... Take it off like usual, add oil and put it back on.

 

Monday is the day I'm going with the Insane Diesel Extreme bypass oil system.

I did exchange a number of e-mails with the folks from Insane Diesel, great customer service, they respond almost immediately.

One of the things I asked them was if there were any warranty implications of the oil bypass system or their oil treatment.

From an oil bypass system perspective the one piece of advice they gave me was that you should continue to follow the manufacturer's recommended oil change intervals. Their claim to fame is that with their system you only need to change your oil once a year, however they recommend you have the oil tested periodically to determine if it needs to be changed. My plan all along was to change it when the truck told me to along with their filter and the factory filter. I do know folks are concerned about the warranty.

From an additive perspective, they were a bit elusive on giving something that you could sink your teeth into. I really want to dump that stuff into my crankcase but everything you read almost everywhere is not to use oil additives so I'm a little paranoid in doing so.

 

I installed Amsoil bypass oil unit on my 2015 F350. The OEM filter filters down to 20 microns. I want to filter down to 2 microns. If you read data from Cat & other engine manufacturers they say that <20 microns cause a fair amount of wear and that the OEM's stop catastrophic wear. I figure the less abrasive particles circulated in my engine the better.

Can you share some of the details on the setup and the installation?

 

Their kit that I bought has the main oil filter & bypass filter that mounts on their base that mounts under truck. You also remove the oem filter & screw their fitting where oem filter screwed into engine. This fitting has two oil line fittings that connect to the base that hold the two aforementioned filters. That's it. It all connects underneath. The oil lines & ends are included. You get all needed parts in kit.
You can't use oem main filter anymore. So you must buy their main & bypass filters from Amsoil.

 

The 6.7 has 2 cooling systems. did you put a by-pass on each cooling system? Seems useless if you only use it on one system.

 

I put the filter on the primary cooling system, the "traditional" cooling system - block, heads ... The secondary is for the transmission, oil, egr ... There is a "coolant crossover" on both systems, not sure if the fluid actually exchanges fluid or not - at some point I'll read this - https://www.vasa.org.au/wp-content/u.../2012_07MS.pdf but for now, one of the systems is clean.

On the oil by-pass filter I went with Insane Diesel Extreme system. Although the website says it needs to be "professionally installed" I did it myself, was pretty easy.

 

My recent bypass thread went begging so good this one got some traction. I thought the AMSoil system looked the easiest to install and well thought out. What I don't like is having to get both filters from AMSoil. What is the story on the Insane Diesel solution?

 

The two cooling systems are totally independent of each other. There is NO cross over of the coolant between them.

 

This the video link explaining the Extreme filter Insane Diesel's video page:




What makes the Extreme filter set up somewhat different from Amsoil's setup is that you keep your factory primary oil filter in place and you pull oil off the oil pressure sensor port. The oil filtered by the bypass filter is returned to the new ported oil fill cap that comes with the bypass filter. It keeps the primary filter and bypass filter completely separate.


The Amsoil uses an adapter on the primary filter's port and puts the new primary filter and the bypass filter on the same housing on the frame...or wherever you choose to mount it. In thinking about about it, I suppose you would not have to use An Amsoil filter for the primary but should use a Amsoil filter designed to be used as a bypass filter.


The Extreme filter comes with a $40.00 filter element that has to be replaced every 15k miles or once a year. If you're out of warranty, you get the oil analyzed every 7.5k miles or twice a year. Replace the filter element, top off the oil and you're good to go to the next analysis... if the oil comes back good. If not, find your problem, fix it, then start over again. I've used Blackstone before and would continue to use them when I do this bypass set up.


And yes, I would continue using the FilterMags on my primary filter, because I already have them...overkill, if you will...

 

I'm reviving this thread because I ordered the FS2500 bypass system from Filtration Solutions. It's shipping this Friday. I was going to go with Insane Diesel's Extreme filter, but decided to go with the FS2500 instead because they post actual numbers for efficiency and flow. They have a specific kit for our 6.7s like Extreme does but I believe the lines are woven stainless steel covered and mounts on the frame. I would like to take some pictures to post up during the install. Instead of starting a new thread, I'll just use this one.
