Yet more proof that some folks are able to screw over other folks, even if unintentionally.
Case in point; the above.
Read over the website; it goes into great detail as to why the CAT oil filters are the best; and it's obvious they presume them to be applicable to all conditions and applications.
The CAT 1R-1807 filter is a good filter, but it does NOT have an internal BP relief valve in it. That's fine as long as your engine has a BP relief valve in the block. Not only does this filter not have a BP valve in it, but neither do any of the xref equivalents from most makers (Wix 57791; Baldwin B7700; Fram PH49A, etc). That's all fine and good.
However, the Ford 6.7L diesel and the GM Duramax diesel have lube circuit designs that use filters with BP valves internal in them because they do NOT have BP relief valves in their engines. (Wix 57151; Wix 57202; other brands similar).
This Karens Transport company is now producing adapters that allow the use of the CAT oil filter in place of the OEM designed filter (and aftermarket equivalents), but do not mimic the necessary BP feature to protect the media and the engine.
If you review the website, you'd get the impression this person has done it all and knows it all. But it's my opinion that these products to adapt the CAT filter to several applications is downright irresponsible and likely will result in long term damage to the engines. Further, there are statements on their website that are just flat uninformed. For example, the presumption that normal OEM filters will soon end up in bypass due to particulate loading. All data proves that this is NOT normal, and even reasonably extended OFCIs don't end up with the filters in BP. Also, as Jim Allen's data has shown us, filters used in the correct application with the correct vis lubes do not go into bypass much at all. And then there's the references to the infamous GM filter study, which is an absurd journey into the world of HALTs, and has zero applicability to our vehicles in our garages.
