Does the 7.3 naturally use a little oil?
Merry Christmas all...
With the kids passed out in a sugar coma and the wife resting I decided to go out and play with my new CB. I also took time to check all the fluids in my truck.
I notice my oil is low about 2.5 qts. I changed my oil about 5 weeks ago and confirmed it was full at the time.
I've driven about 2k miles in that time and I haven't noticed any issues, the starts and idles are great.
Being this is my first diesel, is it natural for a diesel to use oil? I've been chasing a smoke issue, but it doesn't smell like oil and my coolent level is good.
I'm just trying to learn...

I really don't think it's blue. The smoke is very faint and when I try to smell it, it doesn't have the burnt oil smell.
I've been chasing the smoke for months. I had come to the conclusion my injectors were old and I had extra fuel that wasn't fully burning.

Before going to deep into it, when you did the oil change did you recheck the level after running it for a few minutes?
You don't suddenly have an extra 2.5 qts of coolant, do you? If it isn't leaking it, and it isn't burning it, that's the only other place I can think of for it to go.

I thought I checked the oil... Anything is possible, but I inspected the coolent and there is no oil or diesel in it. Nice pink color of the mixed Cat ELC in the bottle.
I'll just keep a close look in it. I have a 800 mile run at the end of the week.
My truck runs great, but I still can't leave well enough alone. I like to tinker with my truck as much as possible.

That's what I'd do, top it off and keep an eye on it for a while. I don't like fixing things that don't need fixed.

I run rotella 5w-20 and only change the oil filter every other oil change. I change oil every 5k miles and oil reports come back good.

Injector Orings will help you lose oil. I'd top it off and keep checking it, just because that seems like a lot all at once. Injector o rings will force your oil into the fuel system, and then burn it. You can tell by the condition of your fuel filter. It'll turn black if you have bad O rings. I wouldn't worry about it unless the level keeps dropping though. Good luck

Some engines just naturally run down to a certain point and then stop. In other words, you may add oil until its full on the dip stick but the engine throws out a quart or so and then maintains the level. My father had a truck that would always throw some oil when it was just filled and "settle" to a specific amount where it would stay for next 5k miles. Just another thought on what might be going on.

I didn't see any mention if the oil filter was filled during the change - there's 2 quarts, like jasonc76 said.
One other possibility is the oil dipstick tube can be loose and providing weird readings.

Oh there is no oil leak. I fixed all of those over the summer. I originally had several, but there is no oil leak.
As previously stated I didn't change the filter with this most recent oil change. I might now have let everything settle enough so I will just keep checking the level over the next few weeks.
The oil pan bolts are good, dip stick is fine, valley is bone dry.
I will check the fuel filter tomorrow! I've wondered about my oRings for a while so that might answer my questions....
