Sacrificial CAT 1R-1807 Oil Filter

[Compression-Ignition]

Filter cutter showed up. If you can find one I think this is where it's at! I think it'll probably work on filters with a diameter from 1.825" - 6.5". But to be safe say 2.0" - 6.375"

Unless I break one of these wheels in short order and find out there is only one place to get them and they turn out to be $50 a piece...I don't think this thing can be beat for $92 shipped! Course I don't know what I don't know. But still...dang!

Donaldson makes Cat filters i believe.

Ivr been running that or the Donaldson DBL7483 on my 19 Duramax. Heavy duty filters for sure.

Absolute unit of a filter! What is the average service life of one of these?

Who knows. Playing a little bit of the mad scientist role here. My tentative plan is to run it for a year. but they are only 25 bucks so I may just do two oil changes a year and change it both times. I just can't imagine it'll be anywhere near used up.

My OEM filter has 236.25 sq. inches of media. This has 984.

With my overthought/underthought modifications I should be adding about 4.25 quarts to my oiling system. I was going 3k-5k on OCI's. After our move and a farther commute and a weight loss program I have bumped the intervals to about 8000 miles. Manufacturer wants a max of 10,000 miles. If I change the oil twice a year I'll be somewhere around 10,000 to 12,000 mile OCI's. If I let curiosity get the better of me I'll end up spending some money on oil analysis to confirm it all. But I don't know if I'll bother. Fuel dilution should be taken care of. And by adding 45% percent capacity the oil should still be in good shape (and then some I would think). And with the filter having 4 times the amount of media and IMO a much better quality...and the numbers I've seen say the OEM filter is 38 micron at 99%. So I should be good to go. Maybe.

But I'm just kinda playing it all fast and loose. Actual service life though? Suppose it depends on your system, I'm guessing a long long time.

That giant filter has a bit over 4 times more media area than the OEM filter per your media area numbers. So whatever OCI you use it's going to be way more capable than the OEM filter, even if your OCI is up to 12,000 miles if the OEM was good for up to 10,000 miles.

12k, that’s it? Even with huge dump diesels that seems low, however, I know very little about this subject!

I'm sure you could actually go much father on these but how do you know without doing a bunch of testing? My OEM filters were 50-60 bucks a piece and I had to buy them right to get that price. So 4 times as much holding capacity at half the cost works out well. I think I could easily go a year and 24,000 miles on the filter, probably longer. But I'd still be hanging on to a few extra quarts of oil at my mid year OCI. And since my oil and filters will be less expensive than testing, I'll probably just change them vs. test for increased OCI's. Probably. Haven't really decided yet.

Though I really do think I've most likely overcomplicated this enough already. Any testing I might do is just going to make me want to chase the perfect oil for my situation. Which will take me away from the Mobil Delvac 5w40 rebate cycles that I have settled into quite comfortably. Then there's also the reasoning that oil filters lose efficiency as they load up (at least that's what I've read on here recently). So I should be staying nice and safe with my paltry 12k oil filter changes.

The higher the filter efficiency, the less efficiency it loses as it loads up - that's what is seen in the ISO efficiency test data. The ISO efficiency rating is the average efficiency from new to nearly fully loaded, so a high efficiency filter can't lose much efficiency from loading per that definition.

Per post 18, this CAT filter is 99% @ 20u, and you say the OEM is 99% @ 38u. What you don't want to do is run a low efficiency filter on a long OCI. A filter that's ISO rated at 99% @ 38u is going to be less efficient than that when over half loaded. The longer the OCI, the more benefit you'll get from a high efficiency oil filter.
