So I think for my application the OLM doesnt cut it, I will UOA and go from there im sure blackstone wont recommend me extending out to 15k on dino in all seriousness.
You may be in for an surprize. What does it matter that the engine was derived from Isuzu. That means it is even easier on oil.
It is a different system than what GM normally uses. It is Isuzu-delivered. Mine goes off every 12K in my Colorado. But the first one went off at 13.6K. I would disregard the OLM - even if it was the more popular/more complex GM version. I recommend the old-fashioned odometer reading oil change method. Electronics go haywire when you least expect it. You may think the reading is true -- but it may not be.
If you want to risk that expensive engine on a $4 electric part that goes haywire, then do it - go for it. Just don't ask others here to comply to your rolling of the dice method.
well said
