oil bypass filter. help.

[zmankicksass]

ok so I bought my first diesel truck and I go to do an oil change on it and I cant locate the filter. After some further investigation I see that the PO installed an Amsoil Oil bypass filter kit thing. What in the heck is it? What does it do? And how do I change the oil on it? DO i need to replace both filters? do they need to come from Amsoil?

Someone please chime in here. Im completely lost.

What kit is it?
Is there the regular stock filter and then another Amsoil or what?
Personally, I'd be scared to know how long he was running the oil 'thinking' it was helping his engine.
I'd change it every 5k-7.5k miles with regular 15W40 oil changing the stock filter every time and the Amsoil filter every 3rd time or so. Now you can run Amsoil oil, but I would only extend the OCI as far as an oil analysis says you can go.

There are two Amsoil filters on it. One appears to be bigger then the other. As far as what kit I couldnt tell ya. Would it be better for me to just remove the damn thing and make it back to stock specs, or is that harder than it sounds.

I can't help ya there, BUT I want to add a Amsoil Bypass to mine ASAP... so IF you decide to remove it... I'd like to buy it if the price is reasonable.

I would imagine to remove it you would need some plugs to plug the feed and return lines. Not sure how they blocked off the stock oil cooler/filter.

Pics?

It's easy to remove. Just trace the lines to where the meet the block. You will find a cap that screws into the original oil filter location. Unscrew it and remove everything. I would keep it and replace both filters, just look for the number on the filters and order them through Amsoil.

Yeah I am going to just keep it. What exactly is the benifit of having it on there?

If you run synthetic, you can use UOA's to extend your drain intervals.

The Amsoil bypass filters out soot and small particles, down to 3 microns.

The OEM filter only filters 68% of 15 micron particles.

Does it look like this:

AMSOIL.com - By-Pass Oil Filter: 2000 Ford F250 Superduty Powerstroke 4x4 Crewcab

The bypass filters a portion of the oil down to 2 microns, which helps extend OCI with UOAs.

IMHO even without a synthetic you can extend an OCI with proper monitoring and filtration.

And the FL1995 is a better filter than ppl give it credit for....18 microns at 98%

68%, not 98%.



And the only reason I push synthetic so much is it is more sheer resistant, and in our HEUI system the oil WILL be getting sheered. Dino will work fine.... just synthetic will work better and last longer.

I have seen that chart before as well but honestly I have no idea where it came from, or who got it or how they got. The link in my prior post is right from FoMoCo...I will go with ford on that one.

Most dinos do pretty well with shear, especially in a 7.3...I have seen UOAs of people running JD Plus50 10w-30 out to 8k in the nasty shear machine they call the 6.0 and it could have go significantly longer.
