Filled my tank up, put some of this in. Now I read what it does, but I tried not to think about it because I didn't want to think it would make my truck run a lot better. I changed about an hour after I put in the Diesel Kleen, then I gave her a test drive. My truck just feels faster or did I let it get to me that it can boost performance somewhat. I'm also guessing changing the oil helped some, but whatever it is, my truck seems to run better.

Its the cetane boost. My truck loves the stuff too. I don't use it in every tank, but I can definitely tell the difference when I do.

yea ive started using it in every tank, and i feel a difference too. not huge but it does seem to run better.

I used it fairly regularly in my old 6.2 that I had and put it in my Cummins as well and no complaints at all, not much difference that I can tell with the Cummins but the 6.2 I had ran better.

i've just started using it before I sold my truck(i actually have 85% of the 1 gallon jug I think) free to whoever wishes to come over and pick it up. Cant ship it, seals been broken.

I love that stuff :D

you might be getting some summer blend fuel too?
I use the diesel kleen every tank and just filled up last thursday and noticed my mileage went up a little so I was thinking the summer fuel was my help.

I've never felt a difference using DC..nor with Stanadyne, or any other additive...maybe it's just that my truck runs awesome ALL the time...:D

BTW, I went back to Stanadyne..:p:

anyone try Diesel kellen or power service with b99?

I noticed the boost and smoother feel the first time I started using Stanadyne.

I use it in every tank now.
