Has anyone ever had any problems with Diesel Kleen additive? Just checking around, picked up some at Walmart and have had good success with it so far. Any long term problems that could arise from using this or other additives? Thx.

 

I use it as well (grey bottle) and have not had any problems. I would look at your fuel filter after the first few tanks of using the additive. You may find above normal "gunk" in the filter as a result of the additive being introduced to your fuel delivery system.....

 

I've been using it for about 7-8 months. Both the grey bottle and now that it's winter, the white with the anti jell. No problems thus far.

 

Alot of guys use diesel Kleen and all i hear is good stuff. I run the grey bottle most the time, but now i am running the white in the winter. I was getting an extra 2 mpg with the grey.
