I used to play with biodiesel, and studied up on the pros and cons, but there is one issue that never occurred to me...and which VW mentions in the 2015 owner's manual: Biodiesel has very low volatility, so fuel that gets into the motor oil as a result of normal blow-by tends to stay there, and dilutes the oil. They strongly recommend against using biodiesel in ANY quantity.
If this is really a problem it would apply to any engine, not just the "newest" ones. In fact, older engines would have more blow-by.
Thoughts? It sounds like a legitimate concern on the face of it.
