Richard:

Personally, I think you wouldn't get much benefit out of filtering the combustion particulates out of your oil. You state that the bypass system will not affect the chemistry of the oil, which is true. The problem is that you already have acids in your oil, and the bypass filter won't change that. Also, if the oil has broken down, the bypass system won't help that either. I'm certainly no expert, but I think that the particulate matter is inconsequential. This is often not the case with hydraulic systems, where clearances are very tight.

I suspect your truck engines are a different matter, since they are liquid cooled, and tend to operate at a steady temperature. That should reduce the amount of moisture held in the oil, and the resultant acidity. I would guess that oil tends to last much longer in those engines, to the point where combustion particulates could build up and become an issue.

If you were to try this system, I'm not sure where you would tap into the engine for the oil pickup. A clue might be found in the "preoiler" products. They have to do the same thing, but I'm not sure how they do it.

Let us know what you decide to do. It is an interesting concept.
