Diesel oils are designed to hold soot in suspension, thus the the quick black color. The only time I have seen oil run clean is with a "Luber-finer" filter system on an old Detroit Diesel that held 64 quarts. The filter was the size of a small trash can and was very expensive to change. We did oil analysis every 10k usually went 50k before changes. For 10-13 quart engines it would not be cost effective.
