Not trying to burst anyone's bubble here here, but just so everyone knows, diesel smoke is unburned fuel. If the cetane rating is low it will smoke more. If it's a higher cetane rating it will smoke less. Didn't know if you knew that or not Gary, you might have just mis-typed what you really meant. If your engine is smoking a lot, then it's not the fuel its your fuel system, pump or injectors.
