Amsoil Synthetic

[Diesel Nut]

I researched the FS2500 and they do put on a great show, but I find that their samples compare similarly with the Amsoil filter. Both are very good filter kits, easily serviced, and very effective. However, the FS2500 is almost 2.5 times the cost of the Amsoil BMK11 single bypass system.

Now, with the BMK11, you have 3 options with filter elements. You can use an EaBP90 (6" long), EaBP100 (8" long), or the EaBP110 (10" long). Usually the Diesel Trucks use either the 100 or 110. The larger the filter the more particles it is capable of trapping and holding without plugging up. For your liberty you can run the larger filters if space allows, its really up to you. Usually the 90 is what we would use on the smaller capacity vehicles as there is less oil and less contamination to deal with.

Nice thing about the Amsoil kit is the BMK11 comes with just about everything you need to install it. The FS2500 you have to acquire your hoses and fittings locally. The only thing missing from the BMK11 kit is a modular oil return, which can be taken care of very easily. On the Ford we have a Billet Aluminum oil fill cap tapped out for an oil fitting so clean oil is returned to the crankase that way. On the Jeep, we may be able to use the Cummins oil fill cap, but I need to verify that.

So, do you have any photo's of the BMK 11 install? i have the dual bypass but have not installed it yet, hearing bad things in the thread about the dual. by the pics on the amsoil site, the 11 is a true bypass, whereas the dual isnt, as all the filtration is going through both filters and not bypassing the main filter and filtering bypassed oil in lesser amount, that would explain the drop in oil pressure.

I'm going to jump on this ban wagon too. Could you pm or e-mail me a parts list for your system? If you have any pics of it, I would be interested in those also. Thanks for all the time that you've put into this.

I have used the dual bypass with great results with my 7.3. I used 5/8 inside dia hoses and all smooth radiused fittings and great uoa samples for 40000 miles with 5w30 heavy duty diesel. no oil change since 2003 no problems all smiles here. for the 6.0 guys order the bk-203 from amsoil for $50 and buy the billet oil filter cap and oil fill cap with some #4 lines and you can add bypass system to the 6.0
