I use delvac. it say's the million mile oil! so I guess I need to change oil at one million mile intervals.![]()
No need for oil change anymore?

Here's a different way to monitor your oil condition right on the truck.

I can get 10,000 miles before I start using oil then I have to keep adding a gallon every week until I reach the 20,000 mark. Oil gets changed and I am back to not having to add oil for 10,000 miles.
What does this tell me???? Yeap something not right is happening to the oil and it is starting to get burned up. Better to change it.
I also note that my oil pressure will start dropping off more as I get closer to oil change time.

When I drove local, I had a 2003 Century day cab with a cat. It never used oil until the 12k mark. It would loose a gallon over two days. Then I'd mentioned it to the mechanic, he'd look on his notes, then realized it was to change the oil.
It did this for the 2.5 years I drove the truck. The engine knew when it was time for a changepuncher Thanks this. -
Hey, I have a question to all those "no-oil-change-is-needed" believers: if your BS lab test are saying its all good and oil is like new so you can keep it forever - then, why is it that after 10-12,000 miles it is getting thin like water, doesn't stick to finger, oil pressure drops and engine is starting using it faster and faster?
In case you have no answer - here is a tip for you all rocket scientists: because engine oil wears out quick from temerature and turns into chicken sxxt, thats why -

The oil isn't "getting thin like water" as you state unless an injector is throwing fuel into the oil. That would show up in an oil sample. Part of the oil sample test is to check the viscosity index. As long as the viscosity index is within prescribed SAE standards for the oil being used, there is no issue. It is rare for oil to get "thin like water" over even extended periods of time unless there is a mechanical problem that is shearing the base oil molecules, fuel in the oil, or water contamination. That is the beauty of oil sample testing, these things will show in a sample and then the problem can be addressed before an engine is totally ruined.
As for your other comment about how the oil doesn't stick to hour finger, it isn't the oil that sticks and is hard to remove from your finger, it is the contamination like soot that sticks and dirtys your finger. I don't usually go beyond 25,000 miles before changing oil, but using a bypass filter keeps my oil clean enough oil change to oil. change that it always wipes off my finger with no residue remaining. Yet, my oil is within a couple of tenths of the viscosity of oil out of the jug. -
we change oil/filters every 15K or 300 hrs whichever comes first, even on my '09 they do this. Every 5th oil change they send a sample to the lab for testing.
