That sounds right. Higher cetane fuel will ignite sooner which leads to more complete burn which means less smoke and a tad more power and efficiency. You could also try powerservice since it's available in larger quantities which lowers you cost per dose. Also the relationship between dosage and increase in cetane isn't linear. The cetane level of the fuel prior to dosing also plays a part with how much of an increase you'll get.
