Diesel's motor was converted to burn coal oil, which Austria had in abundance.

I believe Ford still purchases Navistar motors for its PSD.

Most currently available diesel motors will run on 100% Biodiesel. Hoses will have to be switched as Bio has a higher solvency than Petrodiesel.

Someone also mentioned that Gasahol requires a seperate infrastructure for delivery and distribution. That is not true, Gasahol uses exactly the infrastructure as regular gasoline. Just rubber parts need to be replaced with Vitrol or other material resistant to Alchol.
