It depends on what fuel it’s supposed to run on. Gasoline can be cut with alcohol and diesel can be cut with vegetable oil, but never [usually not] the other way around. This can affect performance very little or a lot, depending on the particular details of the engine and what percent was substituted. Some diesel engines can run with no issues on pure vegetable oil, but most engines need some amount of modifications to run purely on a fuel other than the one they were designed to use.
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.’
