Just try ANYTHING for spills from diesel engines... I recenty (as in
last Thursday) had a spill from the head-cracked turbodiesel Estima
(=Previa) engine I was removing... on my cousin-in-law's driveway.
Lots of carbon particles in the concrete... there's NO way to get
this out. I tried my waterblaster...

Oil is derived from plants, not animals. Ignore the disinformation
derived from certain old oil companies' ignorant ad campains...

Those were steam-turbine ships. most ships these days are diesels.
While diesels can be made to run on just about any thin flammable
liquid (or perhaps even any FLUID), such tarlike liquids might be too
much for diesel injectors?
