As I said I respect Ark,you and D-Roc and have switched from wasting synthetic to optomizing dino,no by-pass system for me but I understand oil and it's uses better through what you and others have posted here. Again thank you.


Yeah, I just picked up a 1998 Dodge Cummins 12V QCSB w/ NV4500 and my first change before I even get it home will be with Rotella 15W40 and a Fleetguard...No plans here to install a bypass on it when there is Donaldson Endurance/Amsoil Filters.
I truly do need synthetic in my climate though...gets kinda cold here

Ahhhh.....the good ole 12V. How many miles on it?
 
215K...higher mileage than I wanted, but the truck is immaculate. Less rust than my 06!
Dana 80's are huge!

215k miles or km? Either way, it's probably barely "broken in" yet. Is there even a known end to the ISB lifecycle?

Syns make sense for D-Roc because he's one of the few that really see E-X-T-R-E-M-E cold, and the cold start pumpability makes a difference for him. But for most of use, it's a moot point.

Plus, cold starts are not near as bad as they were many, many years ago. The old IDI non-turbos with glow plugs and no intake heaters really struggled to turn over fast enough to make the compression heat cycle ignite the fuel. Today's diesels with high-speed/high-torque starters, DI high-pressure fuel injection systems, and intake grid heaters make cold starts fairly uneventful for most of us.

I can recall my college days when I had a 1986 diesel Tempo, and then a 1987 diesel Escort ... Zowie, what slugs.

Ark, I am not dinging your OCI or dino choice...you have wonderful resutls from dino.

I think value and effort when it comes to oil changes.
for an average (lazy) joe like moi, I would drain the oil if I am getting on a creeper to change the filter. I am a newbie to the world of bypass filteration, and most of the ads at the first glance give the impression that it is XYk miles without any intervention.
I have met a few long haul trucker and diesel machanics on the plane and when I mentioned bypass filtration, they looked at me like "english pls" :)
FYI: I use syn in my dmax with a 12 month oci, syn cuz during peak winters the engine is a bit quieter after startup and as a result neighbors dogs are happier!
