Diesel Kleen... use it or loose it?

[gtmgooser]

Guys, I was in the local AutoZone the other day looking at fuel additives and came across this stuff called Diesel Kleen. Now I've never used any additives B4 but was wondering about this stuff. What benefits would I get from it or better yet, what are the negative effects of using it? I've got a 2000 7.3 turbo with 114,000 miles... I want to take care of my investment... Any thoughts or personal experiences would be appreciated.

I use it and have noticed marginally better fuel mileage. But it just gives me piece of mind that the injectors are getting lubed right.

ya i would like to know this also. i have used it before and didnt noticed any major differences but that was only once and i bought another bottle and was going to use it on the next fill up.

Easier starts in winter as well as fuel system cleaning. Use it about every third tank.

which diesel kleen are you using? the one in the white bottle or grey? cuz i know theres two bottles.

I was looking at the grey bottle at the store. Does this stuff make the engine run any quiet'r.... reduce that "diesel knock" noise?

I use the white bottle in the winter when its cold and the grey bottle the rest of the year.
