Extra cetane will NOT help mileage.
Just like using more octane in a gas motor does nothing to help mileage and could do just the opposite.
Cetane and octane refer to the ability to light off.
On a gas motor, really high octane does slow the burn too. Do you want the gas to burn slow or to ignite at a controlled rate, and push on the piston while it is still at the top of the stroke? It does little if it is burning while the piston is down 1/2 way.
The energy is best used at the top of the stroke.
