I thought they would be running around on nut juice by now. Yea, I find it funny to think of filling up the tank with 20 gallons of nut juice. I think you would need a nut juice heater in the tank to keep it from freezing to the medal parts. Maybe the nut juice puts to much emissions for a modern cat to handle. Or the rings can not hold the nut juice against the cylinders. It could be something dangerous like the nut juice causing the tank to expand under pressure until it ruptures.
