FYI Wonder why oil looks dirty after fresh oil is run briefly?

[Joe Hogan]

Here is an interesting video about diesel oil changes. In this case it is a Duramax engine, but applies to most all engines.
At the end of the video is a promo section discussing a Banks product. Some interesting discussion.
I am a fan of Banks products as they appear well tested and accomplish specific goals.

Thanks for posting this Joe. I always wondered why new oil turns black as soon as you start the engine.
