changed oil and its still black. need help

[dieselboy01]

So is it a good idea to change the hpop oil? Maybe every other oil change? Not to derail this thread even more but it is the $500 FS 2500 kit really worth it?

The oil in the HPOP RES is fed from the pan via the LPOP. It circulates just as much as the oil in the rest of the system. If the engine has been neglected there may be some more gunk in the HPOP RES than te rest of the sysem but that is doubtfull. The oil NEEDS to flow through there to fire the injectors. If it just sat there so would you.

Food for thought. If the oil remains clean all the deposits are in the eng and the detergents are not doing their job ?????

Back in the day of non det oil it would come out just as clean as it went in. Pull a rocker cover & find sludge 1/4" thick everywhere.

It is pretty well debating whether or not changing the top oil does anything...it isn't going to hurt anything but I struggle to see how 2-3 quarts of oil will really impact a sump of almost 4 gallons.

^^^ exactly, a significant amount of soot is sub-micronic...meaning no matter how many stinking bypass filters you go, it ain't coming out. CJ-4 oils are designed to suspend the soot in the oil keeping from coagulating and damaging parts of your engine. Dark oil IMHO is nothing to worry about. It will vary truck to truck based on many factors (how old the truck is, what oil is in it, if it is modded in anyway, etc)

Running a Napa Gold filter and Schaeffer's 7000 15w40 oil mine stays clean to 7500 miles. The UOA says I could go further but I feel more comfortable changing it.

Sure it is. Would you use that same "clean" standard for your teeth?

I wouldn't use that same standard of clean for my a$$ but what is your point?

My oil at 7500 miles is a "nice" honey color. The UOA says the oil still has plenty of life in it.....for oil, for me, that is clean.

my first powerstroke's (1994 with 277,000 on it) oil was black as coal even after changing the hpop oil. my latest powerstroke(2002 with 212,000 on it) had and does have oil as clean as any gasser. it's an x fleet truck, i think they took care of it.
nasty oil can show up in diesel or gas engines. i think the oil should show signs of getting dirty after 3,000 miles, but not filthy. if it's filthy in 500 miles, change it. eventually you'll get it clean enough to go 3,000 or 5,000.

My point is, why the hell can't some of you tell it like it is instead of posting total BS like the above. The only way it will be a nice hone color after 7500 miles is if it has been riding in the back still in the jug.

OH MY GAWD.....444-4D doesn't believe me.....guess it is time to off myself.

Where is that frightened emoticon running around waving its hands???
