An all-diesel Germany and fuel logistics

Would an all-diesel Germany improve its logistics beyond using a single fuel stream?

Potentially, through lower refining demands and a wider range of usable feedstocks, provided the machinery was adjusted for the fuels used.

An all-diesel Germany could, in the proposed scenario, use its available fuel more efficiently. Usable diesel is expected to require less refining than some alternatives. Poorer-quality oil and coal-derived products are suggested as possible feedstocks. A claim that Rudolf Diesel's first engine ran on peanut oil illustrates the proposed range of usable fuels. Different fuels would still require adjustments to ignition arrangements or operating settings. Fuel flexibility therefore depends on adapting the machinery to what is available.
