For those interested in SSTP results from Texas A&M university report October 7th 2009 total oil from using soy bean feedstock is 54.4% by weight. do your maths a bushel (60lbs) and you get 4.44gls of oil per bushel. Not quite 5gls got pretty close though and the figures above came from the TAMU report and they ran the tests with SSTP.
