Hey, im just wondering if anyone has noticed if using synthetic oil their truck, that it has "made more oil" in a shorter period of time compared to using non synthetic oil. thanks
First of all, awesome avatar!!! Dale was the man!!!
Doesn't matter if it's conventional, synthetic, or blend.
I know this could be here say but I've heard that since stock trucks still go into regen cause the oil level to rise due to the ECM increasing the pulsewidth of the injectors to spray more fuel during regen to light off the dpf. Inevitably some fuel gets past the rings causing the level to rise and I do know for a fact that cummins calls for a 3 percent oil/fuel dilution oil change required message based on algorithms written into the ECM based on driving habits. Don't believe me.... Try putting around and see how fast u have to change your oil based on the overhead
my feeling is since the regen injects fuel during the exhaust stroke there isnt enough compression to force the rings against the cyl wall and seal it up. thats just from a physics standpoint. why cant they inject a fine spray into the exhaust. outside the cylinder.In my opinion, the mystery of "making oil" is caused more by improper seating of the rings than the exhaust pulse of diesel fuel to the cylinders. Yeah, if there was no regeneration cycle (deleted), even with crappy seating, you'd get much less fuel blow by than with regen enabled. But combine regeneration with poorly seated rings, and making oil is the outcome.
My 2010 doesn't make oil like it did during the first 2000 miles, and I firmly believe that's because I practiced what the Owner Manual preached -- loaded operation during the first 6000 miles of operation is beneficial to the engine. And I loaded it up, and drove it hard during that time. And to my best knowledge, seated the rings nicely.
Am I right, wrong, or hallucinating? :confused013:
I would agree with you for sure! Why can't they inject into the exhaust after the turbo turbine? Why is the EPA such - ahem - ungood for us truck owner?my feeling is since the regen injects fuel during the exhaust stroke there isnt enough compression to force the rings against the cyl wall and seal it up. thats just from a physics standpoint. why cant they inject a fine spray into the exhaust. outside the cylinder.
Same here. I recently changed the oil on my 100% stock truck after 4,500 miles and got exactly 3 gallons out (not including the small amount trapped in the filter). I have 66k total miles on the truck.FWIW, I'm using Rotella T6 5w40 and don't have issues making oil, I get the same out that goes in. 64k miles on the truck and still stock.
