Since rapeseed oil was used to lubricate steam engines, because of its properties of clinging to cylinder walls and resisting being washed off by steam...
"The crop has undergone a great metamorphosis in quality and production since it was first grown as an emergency war measure on a few acres in 1942. At that time, rapeseed oil was considered an essential lubricant because it could cling to water- and steam-washed metal surfaces better than any other oil. Since the naval ships and trains of the time were steam-powered, and with the European and Asian rape oil supplies cut off, Canada was asked to undertake production. " http://www.hort.purdue.edu/newcrop/proceedings1990/v1-211.html and since we have evidence of how incredibly lubricating it is, "In the case of biodiesel oil made from canola, the University of Saskatchewan has shown that a 1% addition to petroleum diesel fuel would help reduce engine wear by 40%" http://www.agr.gc.ca/misb/spcrops/framework_e.phtml#3.2.1 I wonder if the potential for water corrosion is reduced by the presence of that oil, versus the fossil diesel.
