Nitro-XD2??

I found this oxygenating cetane boosting diesel fuel additive at http://www.strokerengine.com/PowerMist.html . Anyone heard of this being used before?

[ellis93]

I've seen something like that in a jc whitney mag. It looked like a GM fuel filter.
I'm no really shure about things like this. Could be a con too. U know like the two magnets that clamped around ur fuel lines

[Remps]

Could be bull, I've never heard of an oxygenating diesel fuel additive before.

[rattlebox93]

well after my fuel and tune up class and learning about diesel fuel boosting the "cetain" will not help hp at all i need to actually lower the cetain to make power so cetain boost= BIG RIP OFF!!

[Remps]

Hmm... Could you be more specific?

[ellis93]

Uh..... Cetane in a diesel is like octane in a gas motor. What makes a gas motor run better 89 or 116. This let's a motor run more timing and compression to make more power while keeping detonation away. Side effect of this= more power. What is questionable is if any additives work.

This really only applies if you change your timing to take advantage of said octane/cetane boost. Just dumping 116 gas into a cavalier won't do a single thing. I doubt you're going to see much of a benefit to whatever boost this brings, but if it does boost Cetane enough to take advantage of through increased timing, you'd have to run it in the truck from then on, or suffer whatever foul things come from timing being too advanced.

[ellis93]

True but he said it wouldn't help anything.

Cetane is the complete opposite of octane. Cetane makes diesel burn cleaner, faster. Octane stabilizes gasoline to allow more timing, compression. Imo, the higher rpms you run, the more benefit you'll see from a higher cetane diesel fuel. A rating around 50 cetane is probably good enough for the 3500 rpm that I see. Cummins recommends a minimum of 42 cetane, 45 in cold weather(I think), and that is fine for a stock engine that isn't supposed to spin faster than 2925 rpm wot in neutral. With my driving habits, I've always noticed a reduction in smoke, and a small increase in mileage and power when using cetane boost in regular diesel fuel. Its benefits will be even more noticed if running stock timing with a turned up pump or larger injectors.

[ellis93]

Ok I looked around and found this:
ocatne number or rating is the measure of the resistance of gasoline against improper combustion or pre detonation of the engine(knocking ,spark n pinging).it is measured relative to the mixture of iso octane (2,2,4 trimetyl pentane )and n-heptane . while as cetane number or rating is the measure of combustion quality of diesel oil or it is the measure of the ignition delay.tthe higher the cetane number of diesel the lesser is the ignition delay.

So I was mostly wrong but the fact is that it helps the motor run better.

just my 2 cents but octane boost and cetain boost is a little bit of a joke if u really read the bottle u would see that it goes up in ppm parts per million the big question is how mant parts per million does it take to actually do ant good . that is where thet make the money the question does it do that to a ( tank full od fuel ) or does it only raise a certain amount to that level ie: 1 gallon of fuel or 20 gallons of fuel

How much benefit one actually sees from additives depends on the quality of the fuel you are using..for example, if I use Shell Vpower diesel, which is a synthetic blend with cetane and lubricants added,(And Shell even says you will lose a bit of low end torque, but gain power and efficency at higher rpms) I don't use any additives at all, but if I get some cheap freebie diesel from work, it makes a noticeable difference to spike the fuel.

i see your thought and agree on half if the product is only sold as a booster that is where i jump off the only additives i do use is antigel and a sulpher susbsitute for lubricity. and being from up north i am shure your fuel has a way differrent additive package than what i get in the midwest but once again that is only my opionion and everybody has one ,some just taste or smell a little different
i do pose another question since cetain only affects ignition and its delay to make more power, would you not have to actually raise the amount of btu's in the fuel to see a gain. and correct me if i am wrong but the amount of cetain in the fuel does it not pertain to how clean the fuel burns and not btu's

[Remps]

I guess it depends on the setup of the truck, and how its being used, the climate its being used in, as to what fuel and additives work best for everybody. Upon further reading up on the V Power fuel, I don't think the canadian version is a synthetic blend. Here it is: http://en.wikipedia.org/wiki/Shell_V-Power Tho none of it pertains to my original question about the OXYGENATING fuel additive!
