Monster Diesel Additive
Comments?
"One quart contains the energy equivalent of 25 gallons of diesel fuel"
Physics disagree on that. If that were the case then an engine that gets 25mpg on Diesel should be able to run 25 miles on a gallon of it. I'd bet it can't.
"Reduces diesel consumption by as much as 15%
Boosts diesel fuel’s energy by 10% for increased power and mileage per gallon"
Contradicting themselves.
"Reduces metal to metal engine wear and friction by as much as 40%, to reduce down time"
Impossible. Fuel does not come in contact with any engine parts. The only items it could potentially work on are the fuel pump and injectors, and they don't have any issues with straight ULSD.
"Winterizes diesel fuel to allow low temperature operation, preventing gelling and eliminating the need for expensive #1 diesel fuel"
What additive doesn't? If you buy winterized Diesel in the first place, adding anti-gel is completely unnecessary.
"Boosts the cetane number by 12.5%--twice the boost of premium gas over regular"
Only 5 points? Pretty much every additive claims that and there are cetane boosting specific ones that claim 8-10 points.
"Eliminates engine knock"
No such thing in a diesel engine in the first place!
"Provides corrosion control in the fuel system"
Water dispersant. Buying good fuel without water in the first place solves that.
"Supplements fuel to make up for the loss in lubricity that occurs when using ultra low sulfur diesel fuel"
Completely unnecessary.
"Changes black exhaust to white by establishing and maintaining the engine’s original fuel injection pattern to burn the fuel more completely"
White smoke is worse. Black is partially combusted fuel, white is non-combusted.
Its clear these guys are not diesel engineers or enthusiasts, just salesmen.

Want additives that actually work?
Look here at this recent test:
http://www.dieselpowermag.com/tech/f...est/index.html
I have used the listed additives in the test and can vouch for their effectiveness.

I stopped reading after your comment about lubrication. I don’t even look to see how old this post is, but I just wanted to reply and say I can’t back up any of their claims but if you’re gonna reply at least know what you’re talking about when they say lubricate they’re talking about injectors nothing at the oil touches know what you’re talking about before you reply. Other people read this that are clueless not trying to be a dick at all, but this is how bad Information get started

They had Nitro-methane in it FFS. That sh it has no place anywhere near any street engine, especially diesel.
"Stop buying all those other additives such as Power Service, Amsoil, FPPF, Howes, Etc...
MONSTER DIESEL! The ONLY All In One Diesel Treatment!
Say goodbye to all the others. This is the one.
THIS ACTUALLY INCREASES POWER AND MILEAGE!
We are on American Chopper January 28th on TLC unveiling the Orange County Choppers built Monster Diesel "Turbo Diesel Powered" Chopper."
So before replying, try to have some understanding of the subject. M'kay?
Beyond that, ULSD doesn't need additives. 20 years of it on the market has proven that.
