As far as I know it is pure methyl alcohol. I was told it was used in the old style printers that schools had back in the day. The kind that made the purple ink. So that gives you an idea of how old it is.
I work for a environmental cleanup and disposal company so if I can't use it I will have it disposed of properly. I just figured It is worth a try to see if I could make some cheap fuel. I bought some more castor oil and it mixed great with the fresh can. I am going to run some through an old engine I have to see if it causes any problems.
