It's hard to say what the reasoning. Ford has on their last few year model power stroke diesels sold in the US a warning that anything over B5 will void the warranty, but in most other countries, no such restriction exists. The conspiracy theorist in me tends to want to think that the oil companies are behind it....now where's my foil hat??

One of the early posts in this thread mention EN 590 as being acceptable. EN 590 is the eurpoean biodiesel standard. Perhaps the US biodiesel "standard", is not acceptable for some reason, or more likely there is no standard formulation that is available widely enough to endorse. Certainly I can understand MB not warranting a sophisticated system such as the Blutek diesel using fuel that Joe Hippie brewed up in a discarded water heater in his barn.
