T6 15w-40 not cleaning engine?

Just got a question for those of you that have been running the new T6 15w...I have a 1000 miles on this oil since last oil change and it still looks like new. All my previous oil changes with T6 5w turned black almost immediately it seemed which would indicate that it was cleaning. Anyone done a change with the new 15w and monitored it lately?

Not sure what you mean. I'm you want clean oil and engine, install a bypass filter.

you're over thinking it... When I first switched to the t5 5w-40 and now the t6 15w-40 the oil looked new for the whole change interval, The synthetic seems to really stand up well in these trucks. The oil turning black does not in anyway shape or form indicate its "cleaning the engine" its merely build up of soot and other matter from the engines process of running.

Your oil and truck is totally fine.

So, i've owned this truck for 18 months, did an oil change immediately when I picked it up and 2 since. First 2 with T6 5w and third with 15w. One change I added Seafoam to the crankcase. I'm going to think of this good looking oil as a positive then.

This is exactly what I've heard from others as well. If it's black, it's doing it's job. The result of cleaning diesel soot. Question is, why do some experience black oil every time and some don't? Mods maybe, larger injectors, smokier truck...?

I have no idea why some are not claiming to have the same black oil as the masses
my truck has always had black oil
no crazy mods ccv delete egr off bypass filtration and OEM filtration

soot is such a fine micron that most say the black oil is a non issue
FS 2500 said it is ok when i asked them why my oil was not golden like their ad

I can send a picture of my oil if it helps anyone. I have the fumoto valve and extra oil. But since swapping to full synthetic I have not had black oil. Could be because I don’t have an egr, def/dpf?

1999 F250 7.3L. With 152k miles running t6 15w-40. Little over 2000 miles and oil looks like it did when it came out of the bottle.

Stock injectors, no ecm tune, ccv re route for about 500 miles. Straight pipe etc. no fuel, injector, or tuning etc.

I had the same results using the t6 5w-40 at 4500 miles it was same color as out of the bottle.

The oil has always turned black in mine after a few miles of driving, same goes for any other diesel I have changed the oil in. Black oil is normal for a diesel, even the pre emissions ones.
