Cetane (CN) isn't an ingrediant in the fuel, it is a measure of a fuel's ignition delay; the period between the start of injection and start of combustion.
In the US, diesel fuel has a CN range from 40-46 for regular diesel, if you can find premium diesel it will be around 45-50. Again, this is a measurement not a content amount.

so you did not tell me what I want to know if you add a cetane addative to a juiced up truck and fellow the directions on the bottle can it have a negitive affect like too much octane for a gas motor....

I believe somewhere in the latest issue of Diesel Power, which I read yesterday, it speaks of good cetane ratings (and Clay hit it right about dead on, as Whit said). I could look it up but alas, im too lazy.

I like this statment ...............and its true

Cetane's greatest benefit is that it promotes pre-ignition resulting in a complete "burn" of the fuel and gives the engines a huge power gain.
