ya but also having a good filtration system should remove most of the "soot" out of the oil. 1 of the oils job is to carry the crud to the filter. Im not saying mine is crystal clear, but you can read the dipstick. now when you drain it, it looks like a black stream unless you put your finger in it and it is pretty much a dark amber. but im also getting rid of it at only 5k, oil is cheap for me so thats why i do it even running full synthetics. i am only getting 17-18 on the open road with a conservative foot though....:dang::pca1:

What some either don't know or have forgotten is the 3rd gen engine with its 3rd injection event puts more soot in to the oil then then 1st or 2nd Gen engines, thus you can't compare 1st and 2nd gen engine oil to 3rd gen oil. A 3rd gen engine with fresh oil in it will look dirty with in a few minutes after start up do to its multiple injection events.

Stratopore filters and a 2 qt Amsoil bypass filter. Never have seen it clear with my truck.
