@Flyfish: Well now your just being silly. You want to compare the contact of a shell with a die for 2 seconds, to an engine. A complex mechanical device that produces 12,000 controlled explosions per minute (assuming 3000 rpm and 4 cyl.). I don't think the hi temp and multiple moving parts of an engine are an apples to apples comparison. Somehow I don't think my dies will ever reach 230°f.
However, if you put any petroleum based lubricant in an engine crank case, it would work. It might not be good for improving the life of the engine, but it would provide a certain amount of lubrication for a period of time.
But lubricating a brass case, so it doesn't stick in a tool steel die, Yes, even vegetable oil would work. Hell you could use butter if you wanted to.
