Is there a way to run a modern diesel generator 100% on vegetable oil? I don't know if this question goes here, a little background: 

I have a 110kva diesel generator which I use to power the pumps of an irrigation system.  Here in Argentina, new soybean oil is considerably cheaper than diesel fuel. I need to know if there is a way to run it on vegetable oil, without damaging or wearing it out excessively, or if I should just give up and keep running it on diesel.

Thanks.
