Eating injector pumps and injectors for lunch gets expensive. As does constantly buying new fuel filters.
Refining fuel is hard. Now, you get yourself a duce and a half or a 1980 rabbit and those things were designed to run on trash fuel. The duce and a half will even burn peanut oil, Jet A or kerosene.
Anything remotely modern will eat itself on your hillbilly diesel fuel. The fuel system in a diesel is a very complex hydraulic system with all sorts of tiny high precision parts. 20 years ago they were running at 1500psi.
Now they run at 15,000 psi. And oh my would you destroy parts fast. New Ram trucks are spitting out fuel pumps for breakfast because bosch built that pump expecting german fuel quality and the north american fuel is shredding them.
Also, emissions certification. You are actually breaking the law by running that fuel on anything that carried any kind of emissions certification when it was new.
