Black oil at 2k?

[jackstraw212]

Hey Guys... I'm new to this site and 6.4s (previous truck was an '04 6.0). I just bought a 2010 F250 and have noticed a bit of vibration at idle on cold starts. I checked the oil, and it seems awfully black and appears to smell a bit like diesel fuel (could be my imagination). Also, the oil level looks to be above the full mark.

I've done a number of searches, and I've read a bunch of threads regarding fuel dilution and regen; however, is it normal for the oil to be overfull and black on a truck with only 2k miles? The truck is at the dealer now, and they mentioned that I should not be inserting the dipstick completely when checking the oil; rather, I should be stopping when it begins to seat on the tube? I don't see where it says this in the owner's manual, so I'm a bit confused.

Any thoughts?

Thanks!
Josh

Is the DPF still on the truck?

[jackstraw212]

Yep, sorry about that. Truck is still completely stock.

That explains the black oil and fuel smell then. Theres a slight fuel dilution issue until you get rid of the dpf

Thanks for info... really appreciate it! It sure is tempting to remove it...

How about the dipstick? Am I really not supposed to seat it completely in the tube when checking the oil?

Not sure about the dipstick situation on the 6.4.

I always fully seat it on my 6.0 though

took mine in for the exact same issue. 2900 miles on the oil and it was way up on the dipstick. turns out the #3 injector was leaking. Just fyi

Josh,

The dealer is right. It's called the short stick method. Do a search on "making oil" and you'll read all about it. Keep and eye on it and it should be okay. Let us know what the dealer says.
