Sweet .... are you running linehaul .... or expedite perhaps ?

We will add an oil bypass filtration system to the engine. We are looking at the OPS1 system.
You may well be able to buy alot more filtration for much less money using off-the-shelf components - with less ongoing costs as a result of less expensive filter elements .... if you are comfortable with figuring out the plumbing and doing the install yourself. Talk to Gary Allen on here as to how.
Dunno what OPS is charging for that system these days .... but it was pretty pricey the last time I checked - I can't imagine that they are giving the elements away either .....
One thing about their "oil refiner" claims - the secondary "evaporator" unit - used to be that they published the temperature that this unit heated the oil to .... as I recall the temperature was 195 to 210 degrees F. It appears that this data has been removed from their website and all literature (wonder
why they are now choosing to de-emphasize that aspect ?
)
Dunno about your DD15 but I know that the oil in the MBE 600 (2.7L inline 5 cyl) in my little Sprinter regularly reaches 190F if it is at all warm out (50F or more ambient) ... and it will reach 160F easily even if it's cold. And my UOA's have never shown any water or A/F whatsoever. Moisture in a crankcase does not need to be heated to 212F in order to evaporate
..... especially if the vehicle is running long and not doing short hops where the engine doesn't fully heat up .....
Having said that, I know some folks running an OPS1 on their CAT C15 that went 100K miles on their first OC after installing the OPS1 ..... on dino oil ..... significant amounts of make up oil likely contribute to that.
You might also talk to Doug Hillary on here about his experience with centrifuge filtration - he's had alot of experience with them on Class 8 rigs down under.

We will take an oil sample and change the bypass filter every 15k miles. We will stay with the factory OCI until we feel it can be extended (based on UOA).
Given filter elements of the same size, the finer the degree of filtration, the more often the elements will have to be changed (no free lunch) But the use of a large element (or even multiple large elements run in parallel) can allow filtration to an extremely fine degree - and still provide a reasonable maintenance interval.
