New Oil Black Already???

[jungledave]

I was wondering if anyone has noticed how dark the oil was in their new trucks? I now have 500 miles on the wifes 05 CTD and the oil is black like it has 5000 miles. Neither one of my last two new trucks, an 02ctd and 04 ctd looked this dirty with so few miles on them. Thanks David L.

This is normal for the "new" 04, 04. 5 & 05's. I forget the specifics but if you do a search for "Black Oil" you get all the explainations from the guru's.....

Mine always looks really nasty, very quickly. The oil analysis I had done was just fine though. Nothing to worry about!

It takes only a few hundred miles to make the oil "black" - it's okay because it's normal.

It is black as soon as you change it and run the motor to fill the filter so you can check the dipstick.

To ease your mind, you could take a sample at your next oil change. Have it analized. I don't do it frequently, but will every now and then. Just helps me feel comfortable that nothing is going horribly wrong.

You don't fill the filter before you start your engine?

Close, but actually this is normal for the 04. 5+ only, the 600 series engines. The 03-04 305/555 engines and the SO's burn very very cleanly and do not blacken the oil for many miles. There is much speculation as to what is the cause of this black oil, however it is definitely normal on the 600's.

Lots of engine oil filters NOT filled when oil changes are done Tim. Mine is one of them as is THOUSANDS every day.

I've heard many a rod knock until filters are full. Every filter on my rigs that can be filled, IS... especially the big one on my Dodge.



Not filling the filter and dry starting the engine is a bad idea if you ask me, besides, it's easy... there's no excuse not to do it.

Tim's right but just because you're doing the "right" thing, it can turn WRONG by letting contamination ruin your best intentions. Yah, I know, the filter is open either way, but it's a lot easier to navigate empty, with less chance for accidental bumps and debris entry. Just a thought. Be careful either way.

Was in the auto repair end 25 plus years. I never heard ROD KNOCKS on anything. Oil psi on most engines in 2 to 3 seconds I bet. Lots of stuff filters are on sideways etc.

it isn't going to harm the engine by not pre filling the filter before start up... cat actually had a TSB to stop filling the filters as they were having contamination failures in the engines [foil bits ending up on clean side of filter when prefilled] i prefill mine but i try and make sure to only pour oil down the dirty side of the filter and not down the center where the clean side is. when i had my tahoe, i wouldn't prefill as the filter sat sideways...

I also fill my filter when changing the oil (tomorrow, as a matter of fact... ), if for no other reason than to keep air from surging through the system. Atmospheric air contains some % of moisture, which has no business in your engine. Filling the filter displaces the air and moisture. Rotella has also helped to reduce the possibility of dropping a bit of foil into the filter by switching to easy-to-remove seals on the gallon jugs. If you still worry about contamination, others on this site use a strainer to catch any dirt or foil that has your engine in its sights. As far as navigating the reinstall, you don't have to fill the filter to the point of spillage, and it's a straight-up shot to the threaded post. I usually spill it when removing it, and end up with a splash of oil on my face, or the top of my head if I move in time.

Well thanks for the replies. It Reminds me of all the PSDs bucket trucks we have at work. I just like clean oil I guess. How do I get my profile to show up below my posts??

Had a 2003 that seemed to keep the oil a lot clearer than the 2005 that I now have. Mine seems to be dirty by the time you run it to check for leaks and to confirm the oil level is correct. Seems to be a natural deal with the 2005's. This has come up before and it appears to be "normal" for the 2005's to darken the oil almost immediately.

I prefill, but buy two gallons and four quarts to do an oil change; easier to prefill with quarts and don't have to worry about the foil on quart bottles.

Jungle Dave,



This will explain how to show your signature.

oil black as tar

no kidding. . I just did the oil change at the dealership, only 3500 kilometres on this change and it's so black even the kid doing the change was shocked.

Here's the oil on my dipstick at about 15,000 miles with DELO 15/40:
