Monster Diesel fuel additive?

[Necessary Evil]

Anyone ever use this stuff? Supposed to add octane or BTU's to ordinary diesel...

nope, never heard of it. I use stanadyne or Optilube.

To what you add to your fuel. Engine's are designed to run on clean diesel fuel, not somebody's brew out of a bottle. Clean, fresh fuel has all the "cetane" your engine need's to do it's job. Frank

In a perfect world that would be true. Unfortunately diesel, much like ethanol, has water in it. It may come from the pipeline clean, but by the time it's sitting in the fuel tanks at the marina, it has water in it. That's why our engines have water separators. If it was always clean, we wouldn't need them.

Cetane in the US is rarely above 50, whereas in EU it's always above 50.

If you need a water remover then Stanadyne does the job very efficiently, because it contains no alcohol or methanol. We add five gallons on every tank at fillup. Of course my five tanks are 800 gal each and it's very expensive to fill.

What you are saying is very true. That's why onboard "quality" filtration is so important. Additive's don't cure contamination. Frank

No they don't, but the op's question wasn't about contamination. We have five filters per engine starting at 30 mic, ending at 2 mics.

Not gonna make an arguement out of it. Your filtering system sound's like it should be. With your usage, you keep fresh fuel in the tank's. Kinda make's my point. Frank
