Apparently, there is growing interest in the use of beef fat or lard as a lubricity additive in the use of road fuels, particularly where petroleum fuels have been blended with biofuels.
Pork or beef fat has a long history of use as a fuel additive, popularly including the "mystery" ingredient of "marvel mystery oil", which was nothing more than a mixture of kerosene, lubricating oil and pork fat. Although, the formulation at the time was based on nothing but serendipity (and its use as a fuel additive, by nothing other than marketing, as it is a potent octane reducer, implicated in a number of engine failures), the use of saturated animal fats as a lubricant for common rail diesel pumps is now backed by scientific evidence.
If one wanted to avoid these "carnivorous" fuels for idealistic purposes, is there any way to find out?
