FS2500 & Amsoil Bypass system

[JBakerFX4]

Seriously looking into doing a bypass on my 6.0. I understand how it works, but I've only seen 2 companies out there in this market the FS2500 and the Amsoil kit. Which is better/differences between the 2? I don't like how the FS mounts on the frame rail and it returns via the drain plug, makes me nervous. opinions? The amsoil kit is a all top mount kit. Debating using the Amsoil filter cap tap and return cap with the FS filter. How will these kits work with 15-40 dino oil?

im not sure but i think that the amsoil return line goes to the drain plug but i dont think that it mounts on the frame. i dont think that it matters which one to get, ive heard that either one is worth getting if you can afford it.

I was looking into this same exact thing last week. I agree the amsoil kits seems to be better. I also believe that amsoil filters down to 1 micron while the fs system filters down to 2-3 microns (I could be wrong). Talk to Raul he's an amsoil dealer he could probably give some better insight on this. Also you can put these on your automatic transmissions as well.

The way I look at it is that the system is pretty pointless since the oil gets sheared down to a low viscosity by the time the normal oil change interval is up anyway.

I kind of agree with you Streak. However, it's the particle filtering capability I'm looking at. We have two issues here; Debre & oil condition. You can have clean sheared oil which is better than dirty sheared oil. I like the idea how these filters get down to <5 mics. Our full flow filter is a 20 mic filter. so IMO the bypass is only for keeping oil cleaner, not longer. Still plan on running 15-40 MC or Delvac. I plan on keeping my truck as long as possible god willing.

where do you install the input line from the truck to the filter?

i can def set you guys up with a bypass kit.... PM me for details.. if we get enough people interested we can do a group buy

I think the idea is to use synthetic oil.
It shears down to a low 30, and it stays really clean for a long time with the bypass filter.

A lot of us get 15 to 20k miles between changes with oil analysis proving very good oil quality still.

I used the Amsoil kit, but I went by a local aircraft hose store and had them make 2- 8' hoses with fittings so that I could mount the filter on the frame rail under the truck.

I mainly just like the extra insurance of knowing that my oil is as clean as possible. I also use BioDiesel (20% to 100% depending...) fuel which has a lot less soot to contaminate the oil.

good ol' sales

They're both comparable in performance, but the amsoil bypass is a less than half the cost of the fs2500. IIRC the fs2500 gets down to .5, and the amsoil goes to 1 micron. With the full flows at 20 micron, the .5 isn't a big enough deal for me to be worried. I'd also run the amsoil full flow filter in addition to the bypass. Half the price is what got my attention. And being that raul is now an amsoil dealer, he should be able to hook you right up. Too bad I already have one.
