amsoil bypass filter?

[dc4]

is there another filter I can use with the amsoil bypass oil filter other than the Eabp100? its probabaly cheaper to find something availible at wallyworld or something.

How does the bypass filter work anyway? I was thinking about doing something like it. Is the oil noticeably cleaner than without the bypass?

I have AMSoil's bypass kit with the dual filter relocation assembly. The full flow filter filters all the oil while a little bit of the oil is routed through the bypass filter and filtered down to 2 microns absolute. It keeps the oil extremely clean....I have 2000 miles on my oil right now (I changed not too long ago and my oil looks like it is fresh out of the jug. Before my bypass assembly the oil would be black after driving around the block.

I think for the first 10-15,000 miles on the bypass filter itself it, does keep the oil cleaner for longer. Amsoil rates the Eabp 100 filter for 20,000 miles. I change my oil every 3-5,000 miles and just my opinion but I think the cleaner the oil the better the mileage gets. In my experience with an 2008 and now a 2010 6.4 that the exhaust regeneration comes on less with clean oil.

why not just put a two micron filter in your reg filter instead of a bypass kit

An oil filter with that fine of a filter mesh can't flow enough oil for our engines. The finer the filter, the harder it is to push the oil through so it goes through slower. If you put that filter on your motor's filter mount (if it was possible) the oil would bypass the filter entirely sensing too much restriction in the filter and you wouldn't have any filtration at all.

The concept of the bypass is that all the oil still goes through a normal full flow filter but each go-around some of the oil (usually around 10% of flow) is "bypassed" and sent through another filter, the (approx.) 2 micron filter to remove all the smaller particles.

There are some newer filters that are designed as "dual flow" which are supposed to do something like this (although it won't ever be quite as good as a real bypass setup) all in one larger filter body. Search for Donaldson ELF7405, I believe this is the best filter in this category. Short of a full bypass system as I currently have, this is the filter I would use and feel pretty good doing so.

Note that the donaldson filter I mentioned is for the 7.3, there is a P-series filter for the 6.4L which is P550528 but admittedly I don't know a whole lot about that filter, just that it is one of the better ones.

yea i guess i didnt consider flow rates.ha that was dumb of me.i know in our helos we use 5 micron filters and still get considerable high flow rates.there has to be a way to do this on a vehicle also
