Amsoil Synthetic

The parts man said that the Baldwin B50 crossed to a Napa Gold 1050 and that the Baldwin 164 (longer version) crossed to a Napa Gold 1704. He couldn't find anything on their efficiency, though. Just that, "since they cross reference that they should be just as efficient." I'm trying to check that out because I don't want to install a bypass filter for nothing! Also, the Baldwin filters have an oil flow restrictor needed to work as a bypass filter. I don't know if the NAPA filters do.
A local truck center said that they'd make up the lines for me. So, I'm on the way to having it all set up. I'm going to collect an oil sample tomorrow, when I do an oil/filter change. That should give me a good base number from which to judge this setup's value. Of course, I don't drive all that much, so it may take some time to make a comparison.

What I have read and I don't know if its true because I havn't talked to anyone from amsoil. They designed the EA filters but hastings makes them. I read that the 164 is like 28 microns but can't find any info on the B50 and what it filters down too but I think you said a hastings rep said 2 microns. Sounds like a good plan if you can find the right filters I know I would be interested in it as well.

The UOA showed increased wear presumably because of lower oil pressure. I can't remember all of the details. I just made a mental note not to relocate the primary filter.

Again I read the same things in other forums that people running the dual bypass have gotten rid of them and gone single because of the lower pressures. Seems this is a 7.3 issue for sure don't know about the 6.0! So don't spend your money on a dual bypass stick to a single at least that is what I have read

One more thing. When you have your hoses made use 1/8 NPT that is to be hooked to the left of the full flow filter and run to the bypass filter and the return line on the right of the full flow filter is 3/8 NPT. I hope I made that understandable

Crystal clear. I was wondering about that.
BTW, the Napa Gold 1704 definitely has flow restriction built into it. I picked up the mount and a 1704, today. When you look at the "business end" of the filter, there are three approx. 1/16" holes for oil to pass through (one in the center and two outer ones.) I doesn't look like a full flow filter with the large center hole and several 3/8" or so holes in a circle around the center hole. Napa lists that filter to be used on refrigerant. It rained, today, so I didn't get anything else done (oil change.) Maybe tomorrow.

The people that were haveing problems with the double bypass, were they 6.0-7.3 or both, just wondering if its a problem with the design of the powerstroke line, or one mtr.

Good question! I don't know to be honest with you, because when I do my searching, and reading its mostly for the 7.3, so I better change that until I know for sure. Thanks for pointing that out

Ya, I just thought Id mention it cause lookin around, I found mention on the 6.0s but nothing on the 7.3 yet.

Okay what I read on the dual bypass for the 7.3 is people think it robs the engine of enough oil pressure to do damage in the long run. The wear numbers have gone up with the dual bypass and after removal the numbers go back into the norm. Just somemore info to make a good decision

That's exactly what I'd read, before. But, I haven't been able to find that thread/forum, again. The safe bet is to just go with a single bypass filter setup. Then, whether it's fact or not is irrelevant.

The 7.3L tends to have a bad whine from the hydraulic hoses amplifing the oil pump noises. We fooled with my dads truck for some time and never could get the whine to go away. Eventually we just pulled the dual filter and went with the single. No more problem.
