More: http://archive.nnytech.net/sgroup/BIOFUELS-BIZ/835/ Blending ethanol with SVO is a different matter - IIRC the best I could get with absolute ethanol was 22% in a stable blend. The ACREVO study reports major emissions reductions by adding 9% ethanol (95%), with SVO, rapeseed oil. "The overall combustion performance of the rapeseed oil are very satisfactory in comparison with the diesel fuel while the rapeseed oil produces almost 40 % less soot than diesel fuel. The different volatility of this fuel respect to the diesel fuel is responsible of the different behaviour of the sampled gas concentrations in the base of the flames while at the end of the flames, both attain almost the same values. It has been established that an addition of 9 % of ethyl alcohol (95 %) bring a great benefit regarding the pre-heating oil temperature. In fact, the presence of alcohol allows a reduction in the inlet oil temperature from 150 ¡C to 80 ¡C. Moreover, the combustion of the emulsion produces less soot and, at the exhaust, the amount is almost one half less than that produced by the combustion of rapeseed oil." http://www.nf-2000.org/secure/Fair/F484.htm Advanced Combustion Research for Energy from Vegetable Oils (ACREVO) You should read that report in full, Edward, if you're thinking you can just mix it and chuck it in. In an old Mercedes diesel maybe. On the other hand, diesels will run on pure ethanol (no need for absolute). See: The Manual for the Home and Farm Production of Alcohol Fuel, Chapter 3 UTILIZATION OF ALCOHOL FUELS, Diesel Engines: http://journeytoforever.org/biofuel_library/ethanol_manual/manual3.html And the archives - it's apparently not without its problems.
