Received my insane diesel oil filter bypass system today for my 2025 6.7 Cummins. Good kit but a few issues. Here’s my review.

Installation of insane diesel oil filter bypass

Now why didnt you give the bypass its own pressure supply rather than a parasitic feed from the new oil filter housing? Did you measure (if any) pressure is suitable for the bypass? What did Insane say about your install? Not sure how the new oil filter housings are fed now...Did they eliminate the internal oil cooler?

That is a pressured supply right out of the oil filter housing. No they did not eliminate the internal oil filter. The line feeding out of the oil filter housing is a plug that gets removed just as you would on the previous model years, just a different location.
How often do you plan on changing your engine oil now that you have this system installed?

I’ll do an oil analysis. I changed the oil for the first time at 1,600 miles. Just did it again at 6,000 with the install and will send that oil off to have an idea and a baseline. I installed a fumoto valve so it’ll be easier to take samples. But I will still probably change at 10-15k but the oil throughout those miles will be much cleaner

Decent ratings on the filter, but the things that limit
oil life in these trucks won’t change. Fuel dilution and soot.
No filter removes fuel dilution. The 25+ trucks should have much less overall, but still potentially a limiting factor.
Modern oil prevents soot from agglomerating, so it’s nearly impossible to filter out when it stays submicron in size.
I’ve ran bypass filters for years on multiple rigs and the changes in the oil specs made the cost not worth the results in diesels, especially the ISB that is relatively easy on oil.

This is where I was going with my initial question.
$700-$900 for an oil filtration system and then changing the oil within the normal interval seems like waste, but that’s my opinion.
To each their own. If it makes someone happy and they see value in it, that’s fine too

Way too much money on any cost:benefit analysis. Even the sub $200 I spent on my last bypass setup was difficult to justify with modern oils.
The days of bypass filters having a substantial impact on oil cleanliness are behind us.
Agreed. I think there’s still a lot of mistruths and inaccuracies floating around out there regarding engine oil and engine technology of today. Still a lot of people who think these engines get the oil “dirtier” than older non emissions trucks from years ago, when in reality it’s the opposite. 10-15k oil change intervals and I was seeing 0.5% soot in the oil overall. Half a percent of soot contamination in 3x the oil interval than what used to be considered the benchmark. That’s impressive. Not to mention, like you said, the improvements in additives that allow the soot to be encapsulated and managed better than what it used to be.
