I know the castor oil improves cylinder piston seal against the rings, so your cylinder pressure should increase, not to mention the benifit of more lubrication. They also mention emisions are also reduced.

their testing showed a 25% increase in MPG. I think I will have to order some Castor oil and a quart of Klotz race oil, and try this for an experiment
