Old Fashion Moth Balls in Diesel Full

[mohok]

I know that a sucker is born every minute. Ran into a old gent today while filling up. He was driving a F350 and told me he had been putting 1 Old Fashion Moth Ball per 3 gal of fuel since he had 8k miles on his truck. The truck now has 110k miles on it with no problems. Claimed he increased his mpg by 2-3 mpg's. I did some research online and found more negative than positive comments. I did find a formula of 1 ball per 4 gals. Is anyone doing this with a Dodge Diesel ???

He's just adding naphthalene (Mothballs)... Solid form... (Mothballs) http://en.wikipedia.org/wiki/Naphthalene Liquid form... (Coleman Fuel) http://en.wikipedia.org/wiki/Naphtha Where it comes from... http://en.wikipedia.org/wiki/Benzene be aware that each has its own abilities to alter the fuels ability to either ignite, burn, etc. May make it earlier or later... Like looking at mothballs I would say its a cetane reducer because its got a really high autoignition temperature where Naptha has a really low autoigintion temperature so that would be cetane booster.
