It turns black pretty quick - not sure about that quick, but if the overhead still says oil change required I would take it back there and make them do it again!
I think a lot of it has to do with the EGR (in cylinder or via the valve) and the soot that it produces... Its just too hard to clean it all out.I agree, its normal on 2004.5 + 5.9's and 6.7's. there must be a reset for the overhead the dealer didnt do. I often wondered if the oil gets black so soon because the oil cooler does not drain when changing oil
2rowdy.. what is a bypass? I am so new to this stuff.. can you explain?Next I look at my oil it will have 15000 miles on it.
I do have a bypass though.
I am going to take my first look around 10K, and every 5K from there until I establish a service interval..Next I look at my oil it will have 15000 miles on it.

I change mine at 5k. That way I get my fuel filter at 10k--every other oil change. That has worked well for 110k for me.Ok.. I am assuming then that I have nothing to worry about and it is normal... that's great. Does this quick discoloration of the oil lead to quicker oil changes..? How often do you guys change oil.. I know it depends on what you do with the truck. I use it mainly as a daily driver plus ocassional towing and hauling etc... I am wondering how often you guys change oil - do you just stick to the oil change intervals mentioned in the schedule?
Wow.. I am learning a lot of stuff from this forum!I am going to take my first look around 10K, and every 5K from there until I establish a service interval..
A bypass is a supplemental filter that filters only a small portion of the oil at a time to a much finer degree. For example the OEM filter filters absolute (98.7%) at 35 microns, the Amsoil bypass filters absolute at 2 microns. So you can see how much smaller of a material you are filtering out. Most wear causing particles are above 5 microns. Bypass filters also help reduce soot loading of oil (which is what turns the oil black). So you get a cleaner oil that lasts longer, and causes less wear to the motor.
I think that they are good for the engine, have one on every rig I own. It will not affect your warranty as its allowing for better oil filtration. The amsoil kit (better filtration and cheaper than the FS2500) is $130 (preferred pricing) plus filters, $35. There are also a few other adapters needed for ease of installation totaling $60.... So about 230 plus the 10 (6 month) or 20 (1 year) fee for preferred customer...Wow.. I am learning a lot of stuff from this forum!
Ah64id, So a bypass is really good for the engine - I am going to think about getting one. How much does that cost? Does it affect the warranty?
Also whey you say you look at your oil, do you personally do the oil analysis. Is there a kit that you can buy to do the oil analysis? Thanks.
