Things I learned today: https://en.m.wikipedia.org/wiki/Mercedes-Benz_OM616_engine The mercedes om615/616/617 diesel runs on any flowable grease, requires no electricity to run, and can hand cranked if you build a reduction gear to do it. But there is no need for that if you have it paired with a manual trans, then just park on a hill or push start. I am sure the mechanical inline Bosch fuel injection pump will be outlawed any day...for reasons.
