Dual Flow oil filters?

[EyesofThunder]

Anyone look into these:

http://www.grainger.com/Grainger/BALDWIN-FILTERS-Lube-Filter-4CTW1

It is a Dual Flow filter, Full Flow and Bypass in one spin on filter. Baldwin's website has pictures, there are 2 different types, but both look well designed.

Seen them before...never once, ever, heard of anyone actually using one, though. I'd expect the cost of paying for a new filter every single time for the little added benefit of a bypass filter would be tricky to justify.

I run a Fleetguard version, LF9080, http://www.cumminsfiltration.com/pdfs/product_lit/americas_brochures/LT36043.pdf on my 11 liter Cummins ISM in my motorhome. BTW, I still run a separate traditional remote bypass too. The LF9080 can be had at www.filterbarn.com for $32 and the LF3542 for $14.

that is the question that I had as well

I have been running the 7317 on my dodge for a few months and my oil stays visibly cleaner longer into the oil change

have not done an uoa

I did contact Baldwin and talk to their tech dept and compare flow ratings for this filter and the stock filter and since the flow ratings were favorable I am trying it

Baldwin dealers are much less expensive that grainger

ymmv

Wow, that is a nice UOA! I might have to look into this one. How well does TBN hold up with a bypass vs none? Does it make a big diff?

Don't know? I never did a UOA before going with this setup. Sorry
