I really don't think that there is any benefit from using it. I don't see how it would damage the injectors or anything at all. That is all we use here and have not had a problem.as many problems as our trucks have just running #2..I personally wouldn't risk it..
what do you benefit from it?
does the benefit outweigh the possible damage to injectors and other fuel components.
One of the reasons JP-4 isn't used any more is because of the low flash point. The Navy used JP-5 in the Carriers because its flash point was higher than JP-4. If you run JP-8 stay away from an additive called JP-8+100. When it was first tested it left engines super clean, however the fuel tanks had to be squeaky clean, if not, the additive removed all dirt, water, algae, whatever was in the tank and clogged up the fuel lines.I used to use JP-4 (yeah, long time ago i know) in my diesels back in the 80's never had a problem, would run about 1 quart to 10 gals, got really good mpg, about 10 mpg better than without. couldn't do it all them time, so it was just every once in a while. really cleans out the engine. JP-8 is even cleaner than JP-4 (or so I am told) so it should be better, so I wouldnt run it straight. becuz it seems the tree huggers got to the jet fuel first, (ie used to be JP-4 and I believe there is no more of that)
