Abstract
Several encouraging statements can be made about the use of vegetable oil products as fuel as a result of the information presented in these symposium papers. Vegetable oil ester fuels have the greatest promise, but further engine endurance tests will be required. These can be carried out best by the engine manufacturers. Microemulsions appear to have promise, but more research and engine testing will be necessary before performance equivalent to the ester fuels can be developed. Such research effort can be justified because microemulsification is a rather uncomplicated physical process and might be adaptable to on‐farm operations, which would be doubtful for the more involved transesterification process. Although some answers have been provided by this symposium, others are still not available; engine testing is continuing throughout the world particularly in those countries that do not have access to petroleum.
