You can cut vegetable oil with ethanol for use in an old diesel engine just fine, 10-20% is fine. Old diesels will run on anything that doesn’t self-ignite too quickly.
I once met a guy who had a old Portuguese tractor. I joked ‘you probably can run it on sunflower oil easily, right?’ - he looked at me and said ‘I could throw in a piece of butter and that thing would burn it.’
