Vege. OK. I remember that gag now.
A word of warning if you run Jet A1 in a normal diesel engine. Jet A1 is very "dry" in lubricants due to the refining process. You will need to add at least a liter of oil per 30 liters of Jet A1. Conversely, I find using Jet A1 in a workshop cleaner far better than kero or diesel as it doesn't leave an oily residue.
And on a similar subject, if you run an engine that required "power kerosene" (e.g. in tractors etc), power kero is 3/4 lighting kero plus 1/4 super grade leaded gasoline.
