It's a 126,000 mile 1998 Jeep with a 4.0 and a six quart sump. Lately it sees about 8 to 10K a year and goes roughly 10 miles or more every time it is started. The oil used most all it's life is Amsoil AMO 10W40 changed annually. No oil consumption that I can tell.
The idea of running a bypass rig is something I have been pondering but the TBN/TAN thing might be the killer.
I've done this. I did it with a Permacool since I already had it mounted. I just used the Dual Guard Cummins thread inserts. I was not too smart at the time and didn't realize that the Cummins filter doesn't have a bypass valve. I had been using 51773 Wix with the 3/4-16 inserts that came with the Permacool.
Every BITOG member has some scheme on the back burner. It may get abandoned as you think about it and acquire new knowledge ..but there's always something.
Here's what I am thinking of doing when I'm done with current testing with 0w-10 oil. I want to expand the sump for longevity without having a cold 8+ quart sump.
I've got a Dual Guard (BMK22). I'll simply install a Permacool sandwich and plumb it to the Dual Guard. I'll retain the #3 lines and fittings that are there to restrict flow in a zero discharge return setting. That should create a variable sump based on the temp/visc of the fluid. The poppet in the Permacool will maintain 2PSID across the mount. That should allow virtually no flow at ambient start and progressive (yet attenuated) flow as it warms.
It should provide for more favorable conditions for TBN retention/moisture removal ..without too much in terms of compromise.
I would love to use this sandwich ..but I haven't taken it apart yet to see if it has some relief mechanism. I don't know how much fluid two EaBP110's can pass even @ 5-6 Cst (I actually imagine quite a bit - but). If I had more confidence, I'd then just plumb full sized lines.

Here's one item I would seriously invest in. You can either get one used ..or buy new from the dealer. Get a laminar sandwich oil:coolant heat exchanger. I think it's about $140 new ..but occasionally you'll find one on Ebay for less than half that. I try to get them for under $50 delivered. They're optional equipment on the 2005 Grand Caravan with HD towing package (one reference).
