This Jaguar as well as my MGB leak no oil or other fluids. Well... except for the gasoline spraying out of the fuel return line onto the exhaust the other day but that was my fault. Cost me 60 bucks to get it towed home which was a bargain and about 30 mins to fix. With the new jack it will take about 5 minutes, if it ever happens again. (And assuming it doesn't explode next time).
